Technical Field

The present invention relates to a vehicle searching navigation technology, and in particular, to a vehicle searching guidance method, a vehicle searching guidance device, a vehicle searching guidance system, and a computer-readable storage medium.

Background

With the increasing popularity of vehicles, more and more large parking lots are produced. These large parking lots are usually installed in places with dense traffic flows, such as commercial centers, large office buildings, public transportation centers, and high-density residential areas, and are used for solving the problem of shortage of parking spaces in these places. However, for such large-sized parking lots having a large coverage area, even including a multi-story structure, it is often difficult for users to clearly remember and find the parking positions of their vehicles, thereby causing inconvenience to the users in parking and finding the vehicles. Therefore, there is a need in the art for a car-finding navigation technology for helping a user quickly and conveniently find a parking position of his vehicle.

Conventional position location navigation techniques are commonly implemented based on GPS positioning signals. However, because the parking spaces in the parking lot are dense, a meter-level positioning accuracy requirement within one meter is provided for the positioning accuracy of the vehicle searching and navigating technology, and common large parking lots such as a three-dimensional parking lot and an underground parking lot are often arranged in an indoor environment shielded by a roof, and the general accuracy of a GPS positioning signal is poor. Therefore, the traditional GPS positioning and navigation technology can not meet the positioning precision requirement of the vehicle searching and navigation technology generally.

In order to solve the problem that it is difficult to find a car in a large parking lot, the prior art provides some indoor car-finding schemes, and the Bluetooth or WiFi signals are comprehensively covered in the large parking lot, and the effect of meter-level positioning is achieved by a way of generating a fingerprint map by sweeping a field in advance, so that the function of indoor navigation car-finding is provided for a user. However, the economic cost of fully covering bluetooth or WiFi signals and generating a fingerprint map by scanning the field in advance is too high, which is not favorable for the wide popularization of indoor navigation vehicle-searching schemes.

In order to overcome the above defects in the prior art, a vehicle searching navigation technology is urgently needed in the field, and the economic cost needs to be reduced while the vehicle searching navigation requirement of a user is met, so that the vehicle searching navigation technology is beneficial to wide popularization.

As described above, for such large-sized parking lots having a large coverage area, even including a multi-story structure, it is often difficult for users to clearly remember and find the parking positions of their vehicles, thereby causing inconvenience to the users in parking and finding the vehicles. Therefore, there is a need in the art for a car-finding navigation technology for helping a user quickly and conveniently find a parking position of his vehicle. However, because the parking spaces in the parking lot are dense, a meter-level positioning accuracy requirement within one meter is provided for the positioning accuracy of the vehicle searching and navigating technology, and common large parking lots such as a three-dimensional parking lot and an underground parking lot are often arranged in an indoor environment shielded by a roof, and the general accuracy of a GPS positioning signal is poor. Therefore, the traditional GPS positioning and navigation technology can not meet the positioning precision requirement of the vehicle searching and navigation technology generally. The scheme that the comprehensive bluetooth or wiFi signal of covering and sweep the place in advance and generate the fingerprint map that prior art provided can reach the effect of meter level location, but its economic cost is too high, is unfavorable for the extensive popularization of indoor navigation car searching scheme.

In some non-limiting embodiments, the car-seeking guidance method provided by the first aspect of the present invention may be implemented by the car-seeking guidance system provided by the third aspect of the present invention. Specifically, the car-finding guiding system comprises a plurality of guiding terminals and the car-finding guiding device provided by the second aspect of the invention. The vehicle searching guiding device comprises a memory and a processor. The memory includes, but is not limited to, the above-described computer-readable storage medium provided by the fourth aspect of the invention having computer instructions stored thereon. The processor is connected to the memory and configured to execute the computer instructions stored in the memory to implement the above-mentioned car-finding guiding method provided by the first aspect of the present invention.

The working principle of the car-finding guiding system will be described below with reference to some embodiments of car-finding guiding methods. It will be appreciated by those skilled in the art that the embodiments of the car-searching guiding method are only some non-limiting embodiments provided by the present invention, and are intended to clearly illustrate the main concepts of the present invention and provide some specific solutions convenient for the public to implement, rather than to limit the whole operation mode or the whole function of the car-searching guiding system. Similarly, the car-searching guidance system is only a non-limiting embodiment provided by the present invention, and does not limit the main implementation of each step in these car-searching guidance methods.

Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a car-finding guiding method according to some embodiments of the present invention.

As shown in fig. 1, in some embodiments of the present invention, when a user needs to take a car and leave a parking lot, he or she may first input license plate information of a target vehicle and pay a parking fee through a payment code electronic scanning terminal or a payment code electronic display terminal at an entrance of the parking lot, or a paper payment two-dimensional code posted at an arbitrary position of the parking lot. In response to the operation of paying the parking fee, the vehicle searching guiding device can judge that the user has the intention of searching for the vehicle, so that the operation instruction of paying the parking fee is used as a vehicle searching request with the license plate information of the target vehicle. Then, in response to the vehicle searching request provided by the vehicle searching user to the guiding terminals such as the payment code electronic scanning terminal, the collection code electronic display terminal and the paper collection two-dimensional code, the vehicle searching guiding device can analyze the vehicle searching request to obtain the license plate information recorded in the vehicle searching request, determine a target vehicle required to be searched by the vehicle searching user according to the license plate information, and determine the current position of the vehicle searching user according to the position of the guiding terminal obtaining the vehicle searching request.

For example, in response to a car-finding request generated by a car-finding user through a payment code image provided by the payment code scanning terminal, the car-finding guiding device can analyze the car-finding request to determine a target vehicle which the car-finding user needs to find, and determine the current position of the car-finding user according to the position of the payment code scanning terminal.

For another example, in response to a collection code image provided by a vehicle seeking user to a payment background of a collection code display terminal such as the collection code electronic display terminal and a paper collection two-dimensional code, the vehicle seeking guidance device may obtain a vehicle seeking request generated by the collection code image from the payment background, and then analyze the vehicle seeking request to determine a target vehicle that the vehicle seeking user needs to seek. In addition, the car searching guiding device can also determine the current position of the car searching user according to the position of the collection code display terminal.

It will be appreciated by those skilled in the art that the above-mentioned solution for generating a vehicle-finding request according to an operation command of a user for paying a parking fee and determining a target vehicle according to license plate information input by the user is only a non-limiting example, which is intended to clearly illustrate the main concept of the present invention and provide a specific solution for facilitating public implementation, and is not intended to limit the scope of the present invention.

Optionally, in other embodiments, the vehicle searching user may also provide the number information of the parking space where the target vehicle is parked to the guidance terminal such as the payment code electronic scanning terminal, the collection code electronic display terminal, the paper collection two-dimensional code, and the like (for example, C100), so that the vehicle searching guidance device determines the target vehicle parked in the corresponding parking space according to the parking space number information.

Optionally, in other embodiments, the vehicle searching user may also input the license plate information and/or the parking space information of the target vehicle through a guidance direction display terminal, a vehicle searching code electronic display terminal and/or a paper vehicle searching code arranged at any position of the parking lot to provide the vehicle searching request. An example of the guidance direction display terminal is shown in fig. 2. Fig. 2 illustrates a schematic diagram of a guidance direction display terminal provided according to some embodiments of the present invention. In the embodiment shown in fig. 2, the guidance direction display terminal may be an LED display screen formed by a plurality of LED units. Then, the vehicle searching guiding device can also determine the target vehicle according to the vehicle searching request and determine the current position of the vehicle searching user according to the position of the guiding terminal obtaining the vehicle searching request.

For example, in response to a car searching request generated by the car searching user through license plate information and/or parking space information provided by the guidance terminal such as a manual input and/or voice input manner, the car searching code electronic display terminal and/or a paper car searching code, the car searching guidance device may parse the car searching request to determine a target vehicle that the car searching user needs to search for, and determine the current position of the car searching user according to the position of the guidance direction display terminal where the input data is obtained.

Further, in some preferred embodiments, the car-searching guiding device may also associate at least one user and a corresponding vehicle in advance, bind the license plate information of the corresponding vehicle to an account of the at least one user, and automatically determine a target vehicle that the car-searching user needs to search for according to the binding relationship between the car-searching user and the target vehicle, thereby avoiding the trouble that the car-searching user needs to manually input the license plate information and/or the parking space information.

Referring to fig. 3A to 3C, fig. 3A to 3C are schematic diagrams illustrating a process of performing association binding between a user and a vehicle according to some embodiments of the present invention.

In the embodiment shown in fig. 3A, a user may create an individual user account through an APP, a public number, a wechat applet, or an official website of a parking lot and input license plate information of one or more vehicles that the user owns or drives frequently into the user account. In response to the license plate information of the one or more vehicles input by the user, the vehicle searching guiding device can associate the user and the corresponding one or more vehicles, and bind the license plate information of each vehicle input by the user to the account of the user.

In the embodiment shown in fig. 3B, the car-searching guidance device may control the monitoring camera in the parking lot to shoot the monitoring image of each parking space, and analyze each monitoring image to screen the getting-off image including the getting-off behavior of the user. And then, the vehicle searching guide device can analyze the get-off images to acquire the face images of the user and the license plate information of the corresponding vehicle. And then, the vehicle searching guiding device can determine the account corresponding to the get-off user according to the face image. In some embodiments, if an account corresponding to the get-off user already exists in the car searching guidance system, the car searching guidance device may directly bind the license plate information obtained through analysis to the account corresponding to the user. On the contrary, if the account corresponding to the get-off user does not exist in the car searching guidance system, the car searching guidance device may create the account corresponding to the get-off user first, and then bind the facial image of the get-off user and the license plate information obtained through analysis to the created account.

In the embodiment shown in fig. 3C, after parking a vehicle in a parking space of the parking lot, a user may attach his/her mobile phone or physical membership card to a Near Field Communication (NFC) identification terminal disposed in the parking space, and/or provide fingerprint information to a NFC identification terminal disposed in the parking space, and/or provide a facial image to a facial identification terminal disposed in the parking space, so as to perform parking registration of the vehicle in the parking lot. The vehicle searching guiding device can acquire fingerprint information, face images and/or card information provided by a user through the NFC identification terminal, the fingerprint identification terminal, the face identification terminal and other verification terminals arranged on the parking space. Then, in response to the fingerprint information, the face image and/or the card information provided by the user, the vehicle searching guiding device can control the monitoring camera at the corresponding position to shoot the license plate image of the corresponding vehicle, and analyze the license plate image to acquire the license plate information of the corresponding vehicle. And then, the vehicle searching guiding device can determine the account corresponding to the user according to the fingerprint information, the face image and/or the card information. In some embodiments, if an account corresponding to the get-off user already exists in the car searching guidance system, the car searching guidance device may directly bind the license plate information obtained through analysis to the account corresponding to the user. On the contrary, if the account corresponding to the get-off user does not exist in the car searching guidance system, the car searching guidance device may create the account corresponding to the get-off user first, and then bind the fingerprint information, the face image and/or the card information provided by the user and the license plate information obtained by analysis to the created account.

After the association and binding of each user and one or more corresponding vehicles are completed, the user only needs to provide face images, fingerprint information, voiceprint information and card information, and/or identity verification code images such as member code images and payment code images to a guide direction display terminal, a vehicle searching code electronic display terminal and/or a paper vehicle searching code and other guide terminals, and the requirement of the vehicle searching guide device for determining a target vehicle can be met.

For example, in response to a car-finding request generated by a car-finding user to a payment code image provided by the payment code scanning terminal, the car-finding guiding device may parse the car-finding request to obtain account information recorded in the payment code image. And then, the vehicle searching guiding device can determine the target account of the vehicle searching user according to the account information, and then determine the target vehicle which the vehicle searching user needs to search according to the target license plate information bound in the target account.

For another example, in response to a car-searching request generated by a car-searching user to a member code image in a parking lot provided by a guidance terminal such as the guidance direction display terminal, the car-searching code electronic display terminal and/or a paper car-searching code, the car-searching guidance device may analyze the car-searching request to obtain account information recorded in the member code image. And then, the vehicle searching guiding device can determine a target account of the vehicle searching user according to the account information, and then determine a target vehicle which needs to be searched by the vehicle searching user according to the target license plate information bound in the target account.

For another example, in response to a vehicle searching request generated by a vehicle searching user to a face image provided by a face recognition module of the guidance direction display terminal and/or the vehicle searching code display terminal, the vehicle searching guidance device may analyze the vehicle searching request to determine a target account corresponding to the face image, and then determine a target vehicle that the vehicle searching user needs to search according to target license plate information bound in the target account.

For another example, in response to a vehicle searching request generated by a vehicle searching user based on fingerprint information provided by the fingerprint identification module of the guidance direction display terminal and/or the vehicle searching code display terminal, the vehicle searching guidance device may analyze the vehicle searching request to determine a target account corresponding to the fingerprint information, and then determine a target vehicle that the vehicle searching user needs to search for according to target license plate information bound in the target account.

For another example, in response to a vehicle searching request generated by a vehicle searching user from card information such as bank card information, stored value card information, or membership card information provided by a card recognition module of the guidance direction display terminal and/or the vehicle searching code display terminal, the vehicle searching guidance device may parse the vehicle searching request to determine a target account corresponding to the card information, and then determine a target vehicle that the vehicle searching user needs to search for according to target license plate information bound in the target account.

Further, in some preferred embodiments, the steps of generating the vehicle searching request, determining the target vehicle and determining the current position of the vehicle searching user can be automatically performed by controlling a monitoring camera of the parking lot by the vehicle searching guiding device. Specifically, the car searching guiding device can control each monitoring camera of the parking lot to shoot monitoring images of each position respectively, and analyze each monitoring image to screen a face image containing face information of a registered user. Further, the vehicle finding guiding device can preferably further perform behavior recognition on the facial images by using a pre-trained behavior recognition model to screen the facial images related to the finding behavior. And then, the vehicle searching guiding device can analyze the vehicle searching requests generated according to the face images to determine target accounts corresponding to the face images, and respectively determine target vehicles required to be searched by each vehicle searching user according to target license plate information bound in the target accounts. In addition, the vehicle searching guiding device can also determine the current position of each vehicle searching user according to the corresponding position of the monitoring images containing the face images. Therefore, the scheme can fully utilize the monitoring cameras distributed all over the parking lot to automatically generate and acquire the vehicle searching request of the user so as to determine the target vehicle searched by the user and determine the current position of the vehicle searching user, thereby further avoiding the trouble that the vehicle searching user needs to manually initiate a vehicle searching function.

As shown in fig. 1, after determining a target vehicle sought by a vehicle seeking user, the vehicle seeking guidance device determines a parking position of the target vehicle according to target license plate information of the target vehicle to determine a guidance direction required to be provided to the vehicle seeking user.

Specifically, in some embodiments of the present invention, the storage device of the car-finding guidance system may store therein the position information of each monitoring camera. In response to a vehicle searching request provided by a vehicle searching user, the vehicle searching guiding device can firstly acquire at least one monitoring image acquired by each monitoring camera of the parking lot and analyze each monitoring image to respectively extract at least one piece of license plate information. Then, the vehicle searching guiding device can compare each extracted license plate information with the target license plate information indicated by the vehicle searching request respectively, and determine the monitoring image containing the target vehicle according to the matched license plate information. Then, the vehicle-finding guiding device can call the position information of the monitoring camera shooting the monitoring image containing the target vehicle from the storage device of the vehicle-finding guiding system, and roughly determine the approximate parking position of the target vehicle according to the position of the monitoring camera. The approximate parking position can be a parking position with parking space marking lines and parking space numbers, and can also be a non-parking position such as a corridor, a corner and the like. Since the position of the camera is not exactly equal to the specific parking position of the vehicle, the approximate parking position can only indicate the approximate region where the target vehicle is parked. At this time, the user can easily recognize his/her own vehicle from a few vehicles in the same area by means of visual recognition after following the guidance of the guidance terminal to the approximate area where the target vehicle is parked.

It can be understood that the target license plate information used in the embodiment may be license plate information manually input by a user, or license plate information automatically acquired from a user account by the vehicle searching guiding device according to the binding relationship between the user and the vehicle. By providing the input interface according to the manually input license plate information and/or parking space information, the invention can normally provide the vehicle searching guide service for the non-member users, so that the temporary users who temporarily stop the vehicle, the old users who are not good at using the electronic equipment, and even the users who do not have intelligent electronic equipment such as a mobile phone can normally use the vehicle. By providing the function of automatically acquiring the target license plate information, the invention can further provide more convenient vehicle searching navigation service for the member users registered with the account, thereby further avoiding the trouble of manually inputting the license plate information and/or parking space information by the member users and improving the efficiency and convenience of vehicle searching guidance.

Further, in some embodiments, the storage device of the car-finding guiding system may preferably store therein monitoring position information of each monitoring camera. In response to a vehicle searching request provided by a vehicle searching user, the vehicle searching guiding device can firstly acquire at least one monitoring image acquired by each monitoring camera in the parking lot and analyze each monitoring image to respectively extract at least one piece of license plate information. And then, the vehicle searching guiding device can compare the extracted license plate information with the target license plate information indicated by the vehicle searching request respectively, and determine the monitoring image containing the target vehicle according to the matched license plate information. Then, the vehicle-searching guiding device can retrieve the monitoring position information of the monitoring image containing the target vehicle from the storage device of the vehicle-searching guiding system, and determine the specific parking position of the target vehicle according to the monitoring position information. In some embodiments, the specific parking location may be characterized by parking space number information. Thus, even if the vehicle searching user does not know the vehicle to be searched, the vehicle searching user can reach the approximate parking area of the target vehicle along with the guidance of the guide terminal, and the target vehicle to be searched can be determined according to the parking space number information provided by the guide terminal.

Optionally, in other embodiments, for a monitoring camera that does not store monitoring position information in advance nor stores camera position information, the car-finding guiding device may further obtain and analyze at least one monitoring image collected by the monitoring camera after determining that the monitoring camera containing the target license plate information is shot, so as to obtain the position information recorded in the monitoring images. Then, the vehicle finding guiding device can determine the approximate parking position of the target vehicle according to the position information obtained by analysis. For example, if the at least one monitoring image collected by the monitoring camera relates to the parking space number information of "C100", the vehicle searching guidance device may roughly determine that the parking position of the target vehicle is near the parking space C100, so as to provide the vehicle searching user with a guidance direction to the parking space C100 by using the parking space C100 as an approximate parking position. Since the parking space C100 and the actual parking space of the target vehicle can be photographed by the same monitoring camera, the distance therebetween is usually short. Therefore, the user can easily recognize his/her own vehicle from a few vehicles in the same area by means of visual recognition after reaching the parking space C100 following the guidance of the guidance terminal.

Further, in some embodiments of the present invention, the vehicle searching guidance device may preferably gradually acquire the monitoring images collected by the monitoring cameras in each parking area of the parking lot based on the monitoring cameras at each fork of the parking lot, so as to reduce the monitoring image data required to be analyzed and improve the speed of determining the parking position of the target vehicle. Specifically, the vehicle-searching guiding device may first acquire fork monitoring images acquired by monitoring cameras disposed at forks between adjacent floors of the parking lot, and analyze the fork monitoring images to determine one or more inter-floor forks through which the target vehicle passes. Then, the vehicle-finding guidance device may determine the parking floor of the target vehicle based on the distance from the inter-floor branch point through which the target vehicle passes to the entrance of the parking lot, or the time when the target vehicle passes through the inter-floor branch point.

For example, if the parking lot entrance is located at one floor, and the inter-floor branch point through which the target vehicle enters the parking lot includes an inter-floor branch point between the one floor and the next floor and an inter-floor branch point between the next floor and the next floor, the vehicle-finding guiding device may determine the parking floor of the target vehicle as the next floor according to the distance from the inter-floor branch point through which the target vehicle passes to the parking lot entrance.

For another example, if the target vehicle is at 11:00 and 11, the vehicle searching guide device can determine the parking floor of the target vehicle to be the underground second floor according to the time when the target vehicle passes through the interlayer fork between the first floor and the underground second floor.

After determining the parking floor of the target vehicle, the vehicle-searching guidance device may further obtain the fork monitoring images collected by the monitoring cameras disposed at the forks between the adjacent parking areas on the parking floor, and analyze the fork monitoring images to determine one or more section forks which the target vehicle passes through. Then, the vehicle finding guidance device may determine the parking area of the target vehicle based on the distance from each section branch point through which the target vehicle passes to the entrance of the floor, or the time when the target vehicle passes through each section branch point, as described above.

After the parking area of the target vehicle is determined, the vehicle searching guiding device can quickly and efficiently determine the specific parking position of the target vehicle in the parking area only by further acquiring and analyzing at least one monitoring image acquired by each monitoring camera in the parking area. According to the scheme, the parking area of the target vehicle is determined according to the fork monitoring image, and then the monitoring images acquired by the monitoring cameras are acquired and analyzed in the parking area, so that the data volume of the monitoring images required to be acquired and analyzed can be greatly reduced, and the speed for determining the position of the vehicle can be greatly increased.

Alternatively, in other embodiments, if the vehicle-finding guiding device cannot further determine the specific parking position of the target vehicle by analyzing the monitoring image after determining the parking area of the target vehicle, it may use the midpoint position of the parking area as the approximate parking position of the target vehicle, and guide the vehicle-finding user to reach the approximate parking position first, and then the vehicle-finding user may simply recognize the own vehicle from a few vehicles in the same area by means of visual recognition.

Optionally, in another embodiment of the present invention, before acquiring and analyzing the monitoring images acquired by the monitoring cameras in the parking lot, the vehicle searching guidance device may preferentially acquire, from a target account of the vehicle searching user, user information related to member information, service information, and the like, and vehicle information such as a type, a brand, and the like of the target vehicle, and then presume a parking area of the target vehicle according to the acquired user information and/or vehicle information, so as to preferentially acquire and analyze the monitoring images acquired by the monitoring cameras in the presumed parking area.

For example, in a parking lot of a membership-based store such as a samm (Sams) supermarket, if a vehicle seeking user is a high-level member of the membership-based store, the vehicle seeking guidance device may acquire member information from a user account thereof, and preferentially acquire and analyze monitoring images acquired by monitoring cameras in a free vehicle washing service area according to the member information to determine a parking position of a target vehicle.

For another example, if the target vehicle is an electric vehicle, the vehicle-finding guiding device may obtain type information of the target vehicle from a user account thereof, and preferentially obtain and analyze monitoring images collected by monitoring cameras in an electric vehicle parking area with a charging pile according to the vehicle type information to determine a parking position of the target vehicle.

For another example, for a parking lot of a large office building, if the car-searching user is an employee of a company in the office building, the car-searching guiding device may obtain its hiring information from its user account, and preferentially obtain and analyze monitoring images collected by monitoring cameras in a free parking area of the company according to the hiring information to determine a parking location of the target vehicle.

The method and the system have the advantages that the user information and/or the vehicle information are acquired from the target account of the vehicle searching user to estimate the parking area of the target vehicle, and then the target vehicle is preferentially searched from the estimated parking area.

It will be appreciated by those skilled in the art that the above-described solution for determining the parking position of the target vehicle based on the monitoring image collected by the monitoring camera is only a non-limiting embodiment provided by the present invention, and is intended to clearly demonstrate the main concept of the present invention and provide a specific solution for the public to conveniently carry out real-time operation, and is not intended to limit the scope of the present invention.

Optionally, in other embodiments, the car-finding guiding device may also determine the parking position of the target vehicle based on a remote start technology and a microwave detection technology. Specifically, in response to a car searching request provided by a car searching user, the car searching guiding device may first remotely start the car by using the car-in-car account authority of the car searching user. In response to the ignition start of the vehicle, the engine of the vehicle vibrates, and the vehicle searching guiding device can monitor the vehicle start condition of the parking area by using the microwave detection devices distributed in the parking areas of the parking lot and determine the approximate parking position of the target vehicle according to the central position of the parking area where the starting vehicle is located. Further, in order to avoid the situation that a plurality of vehicles in the parking lot are ignited and started simultaneously or in a simultaneous period, the vehicles can be started and stopped for a plurality of times according to a predetermined frequency, for example, the vehicles are started for 20 seconds, then are turned off for 20 seconds and then are started for 10 seconds, so that the microwave detection device informs the vehicle searching guide device of the parking area where the vehicles are located. After that, the vehicle searching guiding device can guide the vehicle searching user to arrive at the approximate parking position, and then the vehicle searching user can simply recognize own vehicle from a few vehicles in the same area in a mode of visual identification.

It will be further understood by those skilled in the art that the above solution for determining the position of the target vehicle according to the vehicle-finding request is only a non-limiting embodiment provided by the present invention, and is intended to clearly demonstrate the main concept of the present invention and provide a preferred solution for reducing the data storage amount and the calculation amount, but not to limit the protection scope of the present invention.

Optionally, in other embodiments, the vehicle searching guidance device may also obtain and store parking positions of all incoming vehicles, and extract corresponding position information according to the target vehicle indicated by the vehicle searching request, so as to increase the speed for determining the parking position of the vehicle.

For example, as described above, after parking a vehicle in a parking space of the parking lot, a user may attach his/her mobile phone or physical membership card to the NFC recognition terminal disposed in the parking space, and/or provide fingerprint information to the fingerprint recognition terminal disposed in the parking space, and/or provide a facial image to the facial recognition terminal disposed in the parking space, so as to perform parking registration of the vehicle in the parking lot. In response to the fingerprint information, the face image and/or the card information provided by the user to the authentication terminal, the car-finding guiding device may determine an account of the user according to the fingerprint information, the face image and/or the card information, and add the location information of the authentication terminal to the account of the user. Then, in response to a vehicle searching request provided by the user through the guiding terminal, the vehicle searching guiding device can determine a corresponding target account according to target license plate information indicated by the vehicle searching request, acquire position information of the verification terminal from the target account, and quickly determine a parking position of the vehicle according to the position of the verification terminal.

For another example, the vehicle searching guiding device may obtain a license plate image of an approaching vehicle collected by the vehicle searching guiding device from an approach camera at an entrance of the parking lot, analyze the license plate image to extract license plate information therein, and determine an approach time of the vehicle according to a collection time of the license plate image. And then, the vehicle searching guide device can monitor the running state of the vehicle by utilizing the microwave detection devices distributed in each area of the parking lot, and determine the parking time of the vehicle according to the vehicle flameout signals collected by the microwave detection devices. Then, the vehicle-finding guiding device can determine the driving distance of the vehicle according to the approach time and the parking time of the vehicle, and presume and determine the parking position of the vehicle according to the driving distance. Further, in order to avoid the situation that a plurality of vehicles stop and shut down in the same area of the parking lot at the same time or at the same time, the vehicles can be started and stopped for a plurality of times according to a predetermined frequency, for example, the vehicles are started for 20 seconds, shut down for 20 seconds and then started for 10 seconds, so as to inform the vehicle searching guiding device that the vehicle has reached the parking position through the microwave detecting device. And then, the vehicle searching guiding device can determine an account corresponding to the vehicle according to the acquired and analyzed license plate information, and adds the presumed parking position to the account corresponding to the vehicle. Then, in response to a vehicle searching request provided by a vehicle searching user through a guiding terminal, the vehicle searching guiding device can determine a corresponding target account according to target license plate information indicated by the vehicle searching request, and quickly acquire the presumably determined parking position from the target account to serve as an approximate parking position of the target vehicle.

As shown in fig. 1, after determining the parking position of the target vehicle, the vehicle finding guiding device determines a guiding direction according to the current position of the vehicle finding user and the parking position of the target vehicle, and provides the guiding direction to the vehicle finding user to guide the user to the parking position of the target vehicle. The guiding direction includes, but is not limited to, front, rear, left, right, up, and down, wherein an upward guiding direction indicates guiding information of an upper floor and a downward guiding direction indicates guiding information of a next floor.

In some embodiments of the present invention, the step of determining the guidance direction according to the current position of the vehicle seeking user and the parking position of the target vehicle may be implemented based on a plurality of guidance devices which are previously installed and store installation position information. Please refer to fig. 4 and fig. 5 in combination. Figure 4 illustrates a flow diagram for installing and configuring a boot terminal provided according to some embodiments of the invention. Fig. 5 illustrates a schematic view of a parking lot with a guidance terminal installed provided according to some embodiments of the present invention.

As shown in fig. 4 and 5, before providing the vehicle seeking user with the vehicle seeking guidance service, a constructor of the vehicle seeking guidance system may first install guidance terminals 51 to 54 at a plurality of locations of a parking lot, including but not limited to installing a payment code electronic scanning terminal and/or a payment code electronic display terminal for a parking fee at an entrance of the parking lot, posting a paper payment two-dimensional code at a plurality of locations of the parking lot, installing a guidance direction display terminal shown in fig. 2 at a plurality of locations of the parking lot, installing a vehicle seeking code electronic display terminal at a plurality of locations of the parking lot, posting a paper electronic vehicle seeking code at a plurality of locations of the parking lot, and/or installing a monitoring camera at a plurality of locations of the parking lot. Then, the constructor can input and determine the adjacent guide terminal of each guide terminal to the car-searching guide device according to the position of each guide terminal and the passing state between the guide terminals, and respectively determine the guide direction from each guide terminal to each adjacent guide terminal according to the relative position between each adjacent guide terminal and each guide terminal and the observation direction of each guide terminal observed by the user.

For example, for the guidance terminal 51 mounted on the pillar between the parking space C073 and the parking space C074, the construction worker may first specify the plurality of guidance terminals 52 to 54 closest to the guidance terminal 51, based on the distance from the position of the other guidance terminal to the position of the guidance terminal 51. Then, the construction worker can screen out the guidance terminals 52 that are obstructed by walls or parking spaces and cannot pass through the guidance terminals 51 according to the passing state between the guidance terminals 52 to 54 and the guidance terminal 51, and can determine the plurality of guidance terminals 53 to 54 of the guidance terminals 51 that can pass through as the adjacent guidance terminals of the guidance terminals 51. After that, the constructor can determine the guiding direction from the guiding terminal 51 to the adjacent guiding terminal 53 to be backward and the guiding direction from the guiding terminal 51 to the adjacent guiding terminal 54 to be leftward according to the relative position between each adjacent guiding terminal 53 to 54 and the guiding terminal 51 and the observing direction of the user observing the guiding terminal 51, thereby completing the configuration of the guiding terminal 51 and performing the configuration operation of the next guiding terminal (for example, the guiding terminal 53).

The scheme of configuring the next guidance terminal 53 to determine its neighboring guidance terminals and determine the guidance directions from the guidance terminal 53 to its neighboring guidance terminals is similar to the above embodiment and will not be described herein again.

In some embodiments, after completing the configuration operation of all guidance terminals in the parking lot, the construction personnel may input and store guidance direction information of each guidance terminal to its adjacent guidance terminals in the storage device of the vehicle finding guidance system for the vehicle finding guidance device to call.

As shown in fig. 5, when providing the car seeking guidance service to the car seeking user, in response to the car seeking user performing an operation of paying the parking fee through the parking fee collection two-dimensional code 55 attached to the parking space a043, the car seeking guidance device may obtain a car seeking request generated by a collection code image provided by the car seeking user from a payment background of the parking fee. Then, the vehicle searching guiding device can analyze the vehicle searching request to obtain the cash register image and determine the target account of the vehicle searching user. Then, the vehicle-searching guiding device may call the posting position of the parking fee collection two-dimensional code 55 from a storage device of the vehicle-searching guiding system to determine the current position of the user, and obtain the target license plate information of the target vehicle bound by the vehicle-searching user from the target account of the vehicle-searching user to determine the parking position of the target vehicle.

In response to the result that the (approximate) parking position of the target vehicle is in the space C071, the car-finding guidance device may first invoke guidance directions from the parking fee collection two-dimensional code 55 to its respective adjacent guidance terminals from the storage device of the car-finding guidance system. Then, the car-searching guidance device may determine a next guidance terminal 56 from each adjacent guidance terminal of the parking fee collection two-dimensional code 55 according to the current position of the car-searching user and the parking position of the target vehicle, and acquire a guidance direction from the parking fee collection two-dimensional code 55 to the next guidance terminal 56 from a storage device of the car-searching guidance system as a right direction. Then, the car-searching guidance apparatus may display a guidance arrow pointing to the next guidance terminal 56 to the right on the ground or the wall surface by using a projection device according to the viewing direction of the car-searching user facing the two-dimensional code 55, and/or play a guidance voice to the right by using a speaker to guide the car-searching user to move forward to the next guidance terminal 56.

In some embodiments, the guidance terminal 56 may be selected from the guidance direction display terminals shown in FIG. 2. The guidance direction display terminal 56 can be integrated with a monitoring camera of a parking lot, and shares the same power supply line and communication line with the monitoring camera, so as to save the construction cost of the vehicle searching guidance system. In response to the car-finding request provided by the car-finding user to the guidance direction display terminal 56, the car-finding guidance apparatus may call the installation location of the guidance direction display terminal 56 from the storage device of the car-finding guidance system to determine the current location of the user as described above, and obtain the target license plate information of the target vehicle bound thereto from the target account of the car-finding user to determine the parking location of the target vehicle. Thereafter, the vehicle seeking guide apparatus may further determine a next guidance terminal 57 from the adjacent guidance terminals of the guidance direction display terminal 56 according to the current position of the vehicle seeking user and the parking position of the target vehicle as described above, and determine that the guidance direction of the vehicle seeking user at the guidance direction display terminal 56 is leftward according to the next guidance terminal 57. Then, the car-finding guidance device may light a guidance arrow pointing to the left toward the next guidance terminal 57 on the guidance direction display terminal 56 and/or play a guidance voice to the left using a speaker according to the viewing direction of the car-finding user toward the display terminal 56 to guide the car-finding user to move forward toward the next guidance terminal 57. Further, the color of the guide direction indicating arrow is preferably a color other than green, such as yellow or red, to be distinguished from the green arrow of the security exit.

In this way, the car-searching guidance device can gradually calculate the guidance direction according to the car-searching request provided by the car-searching user to each guidance terminal, so that the car-searching user is gradually guided to go to the parking position of the target vehicle through a simple algorithm. The subsequent guiding manner is similar to the above embodiment, and is not described herein again.

By adopting the scheme of gradually calculating the guide direction, the method can simplify the algorithm for calculating the guide direction to reduce the processing load of the processor on one hand, and can support the application scene that a plurality of people find the vehicle at the same time on the other hand. Specifically, when a plurality of car searching users simultaneously provide car searching requests to different guiding terminals, each guiding terminal respectively provides the current guiding direction for the corresponding car searching user, and the situation that the car searching users go wrong due to mistaken looking at the guiding directions of other people is avoided.

It will be appreciated by those skilled in the art that the above-described solution for calculating the guidance direction step by step is only a non-limiting embodiment provided by the present invention, and is intended to clearly demonstrate the main concept of the present invention and to provide a concrete solution which is convenient for the public to implement, and is not intended to limit the scope of protection of the present invention.

Optionally, in another embodiment, the car-finding guiding device may also determine a plurality of guiding terminals adjacent in sequence at one time according to the current position of the car-finding user and the parking position of the target vehicle, and determine the guiding direction that each guiding terminal needs to display according to the direction from each guiding terminal to the next adjacent guiding terminal. Referring further to fig. 6, fig. 6 is a schematic flow chart illustrating a process of determining a guiding direction according to the current position of the vehicle seeking user and the parking position of the target vehicle according to some embodiments of the present invention.

As shown in fig. 5 and 6, when providing the car seeking guidance service to the car seeking user, in response to the car seeking user performing an operation of paying the parking fee through the parking fee collection two-dimensional code 55 attached to the parking space a043, the car seeking guidance device may obtain a car seeking request generated by a collection code image provided by the car seeking user from a background of the payment of the parking fee. Then, the vehicle searching guiding device can analyze the vehicle searching request to obtain the cash register image and determine the target account of the vehicle searching user. Then, the vehicle-searching guiding device may retrieve the posting position information of the parking fee collection two-dimensional code 55 from the storage device of the vehicle-searching guiding system to determine the current position of the user, and obtain the target license plate information of the target vehicle bound by the vehicle-searching user from the target account of the vehicle-searching user to determine the parking position of the target vehicle.

As shown in fig. 6, after determining the guidance direction of the vehicle seeking user at the parking fee collection two-dimensional code 55, the vehicle seeking guidance apparatus may retrieve the installation location information of the next guidance terminal 56 from the storage device of the vehicle seeking guidance system, and compare the location of the next guidance terminal 56 with the parking location of the target vehicle to determine whether the next guidance terminal 56 is located at the parking location of the target vehicle. If the distance between the position of the next guidance terminal 56 and the parking position of the target vehicle is greater than a preset distance threshold (e.g., 1-5 m), the vehicle-seeking guidance device may determine that the vehicle-seeking guidance task is not completed, so as to use the guidance terminal 56 as a new current guidance terminal and repeat the above operation of determining the guidance direction until the distance between the position of the corresponding next guidance terminal 54 and the parking position of the target vehicle is less than or equal to the preset distance threshold. In response to a comparison result that the distance between the position of the next guidance terminal 54 and the parking position of the target vehicle is less than or equal to the preset distance threshold, the vehicle finding guidance device may determine that the vehicle finding guidance task has been completed, thereby ending the above-described operation of determining the guidance direction.

By adopting the scheme of calculating the plurality of guide directions at one time, the invention can form a complete guide route by lightening the guide terminals arranged at all positions of the guide route, thereby clearly and intuitively guiding the vehicle searching user to the parking position of the target vehicle and avoiding the trouble of repeatedly inquiring the guide directions by the vehicle searching user. Meanwhile, the repeated work of image processing or camera query and the like aiming at the same user or the same vehicle is avoided.

It will be understood by those skilled in the art that the car-searching guidance process based on the parking fee collection two-dimensional code 55 and the guidance direction display terminal 56 is only a non-limiting embodiment provided by the present invention, and is intended to clearly demonstrate the main concept of the present invention and provide a specific solution for the public to implement, but not to limit the scope of the present invention. Optionally, in other embodiments, the car-searching guidance process may also be implemented based on any one or more of a guidance terminal such as a guidance direction display terminal, a car-searching code display terminal, a payment code scanning terminal, a collection code display terminal, and a monitoring camera, and the principle of the car-searching guidance process is similar to that of the above embodiments, and is not described herein again.

It can be further understood by those skilled in the art that the above-mentioned scheme for displaying the guidance direction through the guidance terminal at each position of the parking lot is only a non-limiting embodiment provided by the present invention, and is intended to clearly show the main concept of the present invention, and provide a scheme for providing a car-finding guidance service without an intelligent mobile terminal such as a mobile phone, so that the old user who is not good at using the electronic device, even a user who does not have an intelligent electronic device such as a mobile phone, can use the car-finding guidance service normally, rather than limiting the protection scope of the present invention.

Optionally, in other embodiments, the car-finding guiding device may also send the calculated one or more guiding directions to the mobile phone mobile terminal of the car-finding user, and display the guiding directions corresponding to the traveling direction of the car-finding user on the display interface of the mobile phone mobile terminal simultaneously or one by one according to the current position of the car-finding user, and/or play the guiding directions corresponding to the traveling direction of the car-finding user by using a speaker of the mobile phone mobile terminal. In some embodiments, the mobile terminal of the mobile phone can display the guiding direction corresponding to the traveling direction of the car searching user in the form of text messages and/or arrow icons.

Specifically, with the above car-finding guidance scheme for gradually calculating the guidance direction, the car-finding guidance device may determine the current position of the car-finding user according to the position of the guidance terminal that obtained the car-finding request, as described above, and control the display interface of the mobile phone mobile terminal to display the guidance direction that corresponds to the traveling direction of the car-finding user according to the direction in which the car-finding user observes the guidance terminal, and/or play the guidance direction that corresponds to the traveling direction of the car-finding user using the speaker of the mobile phone mobile terminal.

For the vehicle searching guidance scheme for calculating multiple guidance directions at one time, the vehicle searching guidance device can determine the current position of a vehicle searching user according to the position of the guidance terminal for obtaining the vehicle searching request, then the mobile phone mobile terminal estimates the traveling distance of the user through the step counting function of the mobile phone mobile terminal, monitors the steering behavior of the user through a gyroscope, and then combines one or more guidance directions provided by the vehicle searching guidance device to estimate the current position of the vehicle searching user, so that the guidance directions conforming to the traveling directions of the vehicle searching user are displayed on the display interface of the mobile phone mobile terminal simultaneously or one by one, and/or the guidance directions conforming to the traveling directions of the vehicle searching user are played by using a loudspeaker of the mobile phone mobile terminal.

Based on the description above, the invention realizes the function of vehicle searching and guiding through the two-dimensional code, the monitoring camera and the guiding direction display terminal distributed at each position of the parking lot without laying Bluetooth and/or WiFi equipment in the parking lot or constructing the fingerprint map of the parking lot in advance, can meet the vehicle searching and guiding requirements of users in indoor environments such as a three-dimensional parking lot and an underground parking lot, can be realized by conveniently and low-cost transforming the existing parking lot, and is beneficial to the wide popularization of the vehicle searching and guiding technology.
