The functions that can be implemented by each device in the application scenario shown in fig. 1 will be described in the following method embodiments, and will not be described in detail herein.

To further illustrate the technical solutions provided by the embodiments of the present application, the following detailed description is made with reference to the accompanying drawings and the detailed description. Although the embodiments of the present application provide the method operation steps as shown in the following embodiments or figures, more or less operation steps may be included in the method based on the conventional or non-inventive labor. In steps where no necessary causal relationship exists logically, the order of execution of the steps is not limited to that provided by the embodiments of the present application.

The following describes the technical solution provided in the embodiment of the present application with reference to the application scenario shown in fig. 1.

Referring to fig. 2, an embodiment of the present application provides an intelligent parking management system 20, which includes a first image acquisition device 201, a parking space monitoring device 202, and a data processing device 203.

The first image acquisition devices 201 are arranged at each entrance and exit of the monitoring area, the number of the first image acquisition devices 201 included in the intelligent parking management system 20 can be determined according to the number of the entrances and exits included in the monitoring area, and one or more first image acquisition devices 201 can be installed at each entrance and exit. For example, in the case of a one-way road, i.e. a vehicle can only enter the monitoring area through an entrance or leave the monitoring area through an exit, a first image capturing device 201 may be disposed at the entrance to capture an image of the vehicle entering the monitoring area, and a first image capturing device 201 may be disposed at the exit to capture an image of the vehicle entering the monitoring area; for the case of bidirectional driving, that is, the vehicle can enter and leave the detection area from the entrance and exit at the same time, at this time, at least two first image capturing devices 201 may be disposed at the entrance and exit, some first image capturing devices 201 are used to capture the image of the vehicle entering the monitoring area, and other first image capturing devices 201 are used to capture the image of the vehicle leaving the monitoring area, although only one first image capturing device 201 may be disposed at one entrance and exit, that is, the first image capturing device 201 both captures the image of the vehicle entering and the image of the vehicle leaving the monitoring area. Of course, if one inlet/outlet has N channels, at least one first image acquisition device 201 may be provided for each channel, so as to improve the image acquisition efficiency and prevent missing acquisition.

The first image capturing device 201 may capture image information of a vehicle when it is detected that the vehicle passes through an entrance or an exit, the image information including a vehicle image including a license plate and an image capturing time, and may determine an entry time when the corresponding vehicle enters a monitoring area or an exit time when the corresponding vehicle exits the monitoring area based on the image capturing time included in the image information. Each first image acquisition device 201 has a unique number, the system can determine the position of each first image acquisition device 201 according to the number, and whether the first image acquisition device 201 is used for acquiring the vehicle image entering the monitoring area or the vehicle image leaving the monitoring area, if the first image acquisition device 201 is used for acquiring the image of the entering vehicle, the corresponding image acquisition time is the entering time; if the first image acquisition device 201 is used for acquiring an image of a departing vehicle, the corresponding image acquisition time is the departing time; if the first image capturing device 201 is used to capture an image of an entering vehicle and an image of an exiting vehicle at the same time, it may be determined whether the corresponding image capturing time is the exiting time or the entering time by combining the capturing direction of the first image capturing device 201 and the head portion or the tail portion captured in the image of the vehicle, for example, if the capturing direction of the first image capturing device 201 points to the monitoring area and captures the head portion, it indicates that the vehicle is exiting from the monitoring area, and the corresponding image capturing time is the exiting time, if the capturing direction of the first image capturing device 201 points to the monitoring area and captures the tail portion, it indicates that the vehicle is entering into the monitoring area, and the corresponding image capturing time is the entering time, and if the capturing direction of the first image capturing device 201 points to the outside of the monitoring area and captures the head portion, it indicates that the vehicle is entering into the monitoring area, the corresponding image capturing time is the entering time, if the shooting direction of the first image capturing device 201 points outside the monitoring area and shoots the tail part of the vehicle, it indicates that the vehicle is leaving the monitoring area, and the corresponding image capturing time is the leaving time.

During specific implementation, the installation position of the first image acquisition device 201 needs to ensure that a clear image of the vehicle can be shot, and most importantly, a clear license plate number can be shot. For example, for a larger intersection, the first image capturing device 201 may be mounted on a bracket for fixing a traffic camera at the intersection, so as to maximize the utilization of the existing facilities and reduce the mounting cost; a support for installing the first image capturing device 201 may be separately provided for an entrance or exit of a residential area or a parking lot. Or if the first image capturing device 201 is allowed, the first image capturing device may be a traffic camera at an intersection, or a camera already installed at an entrance or exit of a place such as a residential area or a parking lot, and the cost is reduced by multiplexing existing hardware devices.

Parking stall monitoring devices 202 set up each parking stall department in the monitoring area, and a parking stall monitoring devices 202 can be used to monitor the condition that at least one parking stall is occupied, and each parking stall monitoring devices 202 is used for generating the parking stall state information whether the corresponding parking stall of sign is occupied respectively.

During specific implementation, parking space monitoring device 202 may select a sensor having a small size, a low cost, and a high reliability, such as a proximity sensor, an ultrasonic distance measuring device, an optical distance measuring device, a magnetic sensing device, or a pressure sensing device, and once the parking space is parked in the vehicle, i.e., the vehicle approaches the sensor, the sensor may generate a signal change, and the signal change may be used as parking space state information for determining whether the parking space is occupied.

The specific installation method of the parking space monitoring device 202 needs to be determined according to the selected sensor type, the environment around the parking space, the road condition and other factors.

For example, when parking space monitoring device 202 is a proximity sensor, an ultrasonic distance measuring device, or an optical distance measuring device, parking space monitoring device 202 may be disposed on the ground in or around the area where the parking space is located, wherein parking space monitoring device 202 is configured to generate parking space status information indicative of the occupied parking space when the vehicle approaches parking space monitoring device 202.

Specifically, parking stall monitoring devices 202 can be installed on the ground in the middle of the parking stall, in order to prevent the vehicle from rolling parking stall monitoring devices 202, the space for placing parking stall monitoring devices 202 can be dug out downwards from the ground of the parking stall, so that parking stall monitoring devices 202 sink to the ground, when the vehicle is parked in the parking stall, the vehicle is just located right above parking stall monitoring devices 202, namely, the vehicle enters the monitoring range of parking stall monitoring devices 202, and the sensor inside parking stall monitoring devices 202 can generate signal changes at this moment. Taking the ultrasonic ranging device as an example, when there is no vehicle in the parking space, the ultrasonic wave sent by the ultrasonic ranging device does not encounter the object or the object is far away from the ultrasonic ranging device, so the ultrasonic ranging device does not detect the echo signal or detects that the callback signal is weak, and after the vehicle stops in the parking space, the ultrasonic wave sent by the ultrasonic ranging device encounters the vehicle and then is reflected, so the ultrasonic ranging device can detect the strong echo signal. The detection principle of the optical distance measuring device is similar to that of the ultrasonic distance measuring device. Alternatively, a bracket may be provided beside the parking space, and a sensor such as a proximity sensor, an ultrasonic distance measuring device or an optical distance measuring device may be mounted on the bracket, but the mounting position of the bracket needs to ensure that the vehicle is within the detection range of the sensor after the vehicle is parked in the parking space.

When the parking space monitoring device 202 is a pressure sensing device, the parking space monitoring device 202 may be laid on the ground in the area where the parking space is located, wherein the parking space monitoring device 202 is configured to generate the parking space state information representing that the corresponding parking space is occupied when the vehicle presses the parking space monitoring device 202. The pressure sensing device comprises a pressure sensor, namely, the pressure sensor is used for converting pressure into an electric signal through the piezoelectric effect of a material (such as PVDF (polyvinylidene fluoride)), when a vehicle is parked in a parking space, the pressure sensing device outputs the electric signal under the heavy pressure of the vehicle to indicate that the parking space is occupied, and when the vehicle is not parked in the parking space, the pressure sensing device does not receive pressure and does not output the electric signal. The pressure sensing device is not afraid of vehicle rolling and is not easy to lose, the maintenance cost of the parking space monitoring device 202 can be reduced, and the pressure sensing device has the advantage of being convenient and fast to install.

In practical application, the pressure sensing device can output an electric signal when being pressed to provide electric energy for the whole pressure sensing device, so that an additional power supply device is not required to be provided for the pressure sensing device, and the installation cost and the installation difficulty are further reduced.

When the parking space monitoring device 202 is a magnetic sensing device, the magnetic sensing device may be buried under the ground of the parking space region, so that the magnetic sensing device is invisible to the pedestrians, thereby reducing the risk of equipment loss and reducing the overhead of system maintenance. Of course, the magnetic sensing device can also be directly laid on the ground in the area of the parking space, so that the construction difficulty can be reduced. Or a bracket may be arranged on the ground around the parking space, and the magnetic sensing device may be mounted on the bracket, but the mounting position of the bracket needs to ensure that the vehicle is within the detection range of the magnetic sensing device after the vehicle is parked in the parking space. The magnetic sensing device is used for generating parking space state information representing that a corresponding parking space is occupied when a vehicle is close to the parking space monitoring device 202, when the vehicle is parked in the parking space, the vehicle is close to the magnetic sensing device, the magnetic sensing device can output an electric signal to indicate that the parking space is occupied, and when the vehicle is not parked in the parking space, the magnetic sensing device cannot output the electric signal.

During specific implementation, parking stall monitoring devices 202 also can integrate multiple sensors, improve the monitoring degree of accuracy to the parking stall. The parking space detection device can be powered by a solar battery, and can also obtain electric energy through a power supply cable circuit laid underground.

The sensor such as a proximity sensor, an ultrasonic distance measuring device, an optical distance measuring device, a magnetic sensing device or a pressure sensing device is adopted, the system cost can be reduced, the sensor is small in size and convenient to install, the sensor does not occupy a ground road, and some sensors can even be buried under the ground and cannot be perceived by a pedestrian, so that the equipment loss risk can be reduced, and the system maintenance expense can be reduced.

In specific implementation, the parking space monitoring device 202 may send the parking space state information generated by the parking space monitoring device 202 to the data processing device 203 through a communication device, which may be a wireless communication device or a wired communication device. In practical applications, one communication device may be configured for each parking space monitoring device 202; in order to save resources, a plurality of parking space monitoring devices 202 may share one communication device, and generally a plurality of adjacent parking space monitoring devices 202 may be connected to the same communication device. The parking space monitoring device 202 and the communication device can be electrically connected through a circuit, and the circuit can be embedded below the ground.

The data processing device 203 is configured to determine a vehicle using a parking space based on a matching result of the image information acquired by each first image acquisition device 201 and the parking space state information generated by each parking space monitoring device 202.

Specifically, the data processing device 203 may determine the staying time period of each vehicle in the monitored area based on the image information acquired by each first image acquisition device 201, and screen out candidate vehicles whose staying time period in the monitored area exceeds a preset time period.

For example, the number plate of a vehicle entering the monitoring area, the entering time and the leaving time can be recorded through a first list, and one row in the first list records the information of one number plate. Specifically, the data processing device 203 identifies the license plate number in the vehicle image, determines the entry time when the vehicle enters the monitoring area based on the image acquisition time corresponding to the vehicle image, and stores the license plate number and the entry time of the vehicle into a first list; and when the vehicle is identified to leave the monitoring area, storing the leaving time of the vehicle to the row of the license plate number of the vehicle in the first list. The data processing device 203 can determine the stay time and the stay time of each vehicle in the monitored area based on the entering time and the leaving time of each vehicle recorded in the first list, and if the entering time of the license plate number of 'Jing AXXXXXX' is 10:20 and the leaving time is 11:20, the stay time of the vehicle in the monitored area is 10: 20-11: 20 and the stay time is 1 hour. The license plate number included in the image can be identified by adopting the existing image identification mode, and the specific process is not repeated.

In specific implementation, the charging is not performed for the vehicle whose staying time does not exceed the preset time, so that the vehicle information whose staying time does not exceed the preset time in the first list can be deleted. When the vehicle has left the monitoring area and the vehicle has paid for parking, the information for the vehicle in the first list may be deleted.

The preset time period in the embodiment of the present application may be set according to actual requirements, for example, the preset time period may be 20 minutes or 30 minutes, and is not particularly limited.

Specifically, the data processing device 203 may determine the occupied time period corresponding to each parking space based on the parking space state information generated by each parking space monitoring device 202, and screen out candidate parking spaces with occupied time length exceeding the preset time length.

For example, the occupied situation of each parking space in the monitoring area can be recorded through the second list, and one line in the second list records information of one parking space, including the parking space number, the occupied starting time and the occupied ending time of the parking space. Specifically, the data processing device 203 determines the occupied starting time and the occupied ending time of each parking space based on the parking space state information generated by each parking space monitoring device 202, and can determine the occupied time period and the occupied duration corresponding to each parking space based on the occupied starting time and the occupied ending time of each parking space, if the starting time corresponding to the No. 1 parking space is 10:30 and the ending time is 11:15, the occupied time period of the No. 1 parking space is 10: 30-11: 15, and the occupied duration is 45 minutes.

In specific implementation, if the time length that the vehicle stays in the parking space does not exceed the preset time length, the charging is not performed, and therefore, if the occupied time length corresponding to a certain parking space in the second list does not exceed the preset time length, the information such as the occupied starting time and the occupied ending time of the parking space corresponding to the parking space in the second list is deleted.

Wherein the data in the first list and the second list are dynamically updated in real time.

The data processing device 203 may screen out candidate vehicles having a stay time length exceeding a preset time length in the monitoring area based on the data in the first list, screen out candidate parking spaces having an occupied time length exceeding the preset time length based on the data in the second list, then match the stay time period of each candidate vehicle with the occupied time period of each candidate parking space, and determine the vehicle using the parking space and the number of the parking space used by the vehicle based on the matching result.

The matching method executed by the data processing device 203 includes: for any candidate parking space, if the staying time period of only one candidate vehicle is matched with the occupied time period of the candidate parking space, determining that the candidate vehicle is the vehicle using the candidate parking space; if the stay time periods of at least two candidate vehicles are matched with the occupied time periods of the candidate parking spaces, determining that the candidate parking spaces are not used by the at least two candidate vehicles; and if the stay time period of no candidate vehicle is matched with the occupied time period of the candidate parking space, determining that no candidate vehicle uses the candidate parking space.

Specifically, when the occupied period of the candidate parking space is included in the stay period of the candidate vehicle and the difference between the occupied period of the candidate parking space and the stay period of the candidate vehicle is smaller than a preset value, it may be determined that the occupied period of the candidate parking space and the stay period of the candidate vehicle match. For example, the parking time period of the candidate vehicle A is 10: 20-11: 20, the occupied time period of the parking space No. 1 is 10: 30-11: 15, the preset value is 20 minutes, it can be determined that the parking time period of the candidate vehicle A is matched with the occupied time period of the parking space No. 1, and the parking time period of the candidate vehicle B is 10: 25-11: 10, so that the parking time period of the candidate vehicle B is not matched with the occupied time period of the parking space No. 1.

For example, when it is detected that a vehicle is parked in the parking space No. 1, the start time of the parking space No. 1 is recorded, when it is detected that the vehicle leaves the parking space No. 1, the end time corresponding to the parking space No. 1 is recorded, and the vehicle whose entry time is before the start time and whose exit time is after the end time is inquired in the first list, if the difference between the entry time and the start time is not less than the first preset value and the difference between the exit time and the end time is not less than the second preset value, the vehicle may be tentatively set to use the parking space No. 1, and if no other vehicle meets the above conditions, the vehicle may be finally determined to use the parking space No. 1.

In specific implementation, the data processing device 203 may further execute the following method: and for any candidate vehicle, if the stay time period of the candidate vehicle is not matched with the occupied time period of each candidate parking space, determining that the candidate vehicle does not use the parking space. That is, when the vehicle leaves the monitoring area, there is no matching parking space, which means that the vehicle does not use the parking space in the monitoring area, then the vehicle is not charged.

For the condition that the vehicle needs to be charged, the data processing device 203 can identify the license plate number based on the image information of the vehicle using the parking space, determine the occupied time of the parking space based on the parking space state information of the parking space used by the vehicle, namely the parking time of the vehicle, determine the parking fee to be paid according to the preset charging mode and the parking time, acquire the vehicle owner information corresponding to the vehicle based on the license plate number, and push the parking payment information to the vehicle owner, so that the vehicle owner completes the payment of the parking fee, or can directly deduct the parking fee from the payment account number bound by the vehicle owner.

In addition, based on two kinds of information, namely image information acquired by the cameras at the inlet and the outlet and parking space state information generated by each parking space monitoring device 202, whether a vehicle passing through the road uses a parking space beside the road is judged, and the identification accuracy is improved.

In one possible embodiment, the parking space monitoring device 202 may be a second image capturing device suspended above the parking space, and the second image capturing device is used for capturing the license plate image of the vehicle when the vehicle is parked in the parking space.

During the concrete implementation, can erect track or rope above a plurality of parking stalls, install mobilizable pulley truck on track or the rope, second image acquisition device can fix on the pulley, the pulley can be along track or rope at a plurality of parking stalls top round trip movement, and gather the license plate image of the vehicle that each parking stall was berthhed, a plurality of parking stalls can be monitored simultaneously to such second image acquisition device, and the cost is reduced, and the mode of hoist and mount can reduce the occupation to ground passageway, prevent that second image acquisition device from suffering destruction. The track or the rope may pass through the branches, so as to streamline the housing for accommodating the trolley and the second image acquisition device and reduce the volume and the weight of the trolley and the second image acquisition device as much as possible.

Specifically, the second image capturing device may first detect whether there is a newly parked vehicle, and if there is a newly parked vehicle, control the scooter to move to a parking space of the newly parked vehicle, capture a license plate image of the vehicle, and send the license plate image to the data processing device 203.

Based on this, the data processing device 203 may be configured to: determining the stay time of each vehicle in the monitoring area based on the image information acquired by each first image acquisition device 201, and screening out candidate vehicles of which the stay time in the monitoring area exceeds the preset time; identifying license plate numbers of vehicles occupying corresponding parking spaces based on the license plate images acquired by the second image acquisition devices; and for any parking space, if the license plate number of the vehicle occupying the parking space is consistent with that of any candidate vehicle, determining that the candidate vehicle is the vehicle using the parking space.

Accordingly, the data processing device 203 may determine the length of time each vehicle has stayed in the monitored area based on the entry time of each vehicle stored in the first list. And when the vehicle is identified to leave the monitoring area, storing the leaving time of the vehicle to the row of the license plate number of the vehicle in the first list. The data processing device 203 can determine the stay time of each vehicle in the monitored area based on the entering time and the leaving time of each vehicle recorded in the first list, and delete the information of the vehicles in the first list, wherein the stay time does not exceed the preset time.

When the vehicle is parked in a certain parking space, the second image capturing device corresponding to the parking space captures the license plate image of the vehicle parked in the parking space, and sends the license plate image to the data processing device 203. The data processing device 203 identifies the license plate number of the vehicle occupying the parking space based on the license plate image acquired by the second image acquisition device, compares the license plate number with the license plate numbers in the first list, and determines that the vehicle corresponding to the license plate number is parked at the parking space if the same license plate number exists. When it is detected that the vehicle leaves the parking space or the monitoring area, the data processing device 203 may determine the occupied time of the parking space, that is, the parking time of the vehicle, based on the ending time when the vehicle leaves the parking space and the starting time when the vehicle parks in the parking space, determine the parking fee to be paid according to a preset charging mode and the parking time, acquire vehicle owner information corresponding to the vehicle based on the license plate number, and push the parking payment information to the vehicle owner, so that the vehicle owner completes payment of the parking fee, or may directly deduct the parking fee from the payment account number bound by the vehicle owner.
