The basis that this scheme was realized needs real-time networking, gets on or off the bus and all need brush the face, and installed relevant APP on passenger's the mobile client.
However, when the prior art is applied, the riding mode of the bus is changed, so that some passengers, especially old passengers, are not suitable for the charging mode, and further a certain degree of confusion may exist in the process of switching from the full fee deduction system to the mileage payment system, and further poor experience is caused.
Disclosure of Invention
The invention aims to solve the technical problem of realizing the sectional payment on the basis of realizing the noninductive fee deduction system switching of a user, avoiding the confusion generated during the system switching and further improving the user experience.
The invention solves the technical problems through the following technical means:
in a first aspect, the invention provides a non-inductive interaction method based on Internet of vehicles and edge computing, which is applied to a vehicle-mounted terminal and comprises the following steps:
obtain the information of punching the card that current passenger got on the bus to obtain the first facial data when current passenger got on the bus, wherein, facial data includes: one or a combination of a facial optical image, a depth map;
binding the card swiping information with first face data information;
obtain the second facial data when current passenger gets off the vehicle-hour, compare second facial data and first facial data, under the condition that the two matches, generate corresponding first deduction information to with first deduction information and current passenger's facial data send to the receiving terminal, so that the receiving terminal sends first deduction information and goes out the next equipment of punching the card that is used for current passenger to punch the card and receive, wherein, facial data include: one or a combination of the first face data and the second face data.
Optionally, before the step of obtaining the card swiping information of the current passenger getting on the vehicle, the method further includes:
acquiring second fee deduction information of the transfer passenger when the vehicle-mounted terminal enters a signal range;
the obtaining of the card swiping information of the current passenger getting on the bus comprises the following steps:
obtaining card swiping information of the current passenger getting on the bus, and matching the card swiping information with card information in the second fee deduction information;
if the two are matched, the amount of money in the corresponding card is changed according to the second fee deduction information; then executing the step of binding the card swiping information with the first face data information;
and if the two are not matched, directly executing the step of binding the card swiping information and the first face data information.
Optionally, the obtaining of the first facial data of the current passenger when boarding includes:
comparing the first facial data with first facial data of other passengers stored in the vehicle-mounted terminal to obtain similarity;
acquiring additional features for the first face data when the similarity is greater than a preset threshold, wherein the additional features include: one or a combination of other facial features, clothing features, and posture features.
The inventor finds that in the prior art, when the face of the vehicle is brushed during getting on and off the vehicle, the vehicle-mounted terminals are required to be connected with the server in real time, so that the vehicle-mounted terminals are kept connected with the central data server in real time, and great pressure is applied to a reading interface of the central data server; even if the vehicle-mounted terminal is wirelessly connected with the central data server only when the vehicle-mounted terminal is close to a station, thousands of buses in each city, various management terminals and mobile phone terminals can cause little pressure on a wireless port of the central data server. In the embodiment of the invention, the vehicle-mounted terminal is mainly communicated with the receiving end of the platform, and the receiving end can be connected with the central data server by using wired communication, so that the excessive pressure caused by the excessive number of the terminals on the wireless port of the central data server can be avoided, the wired connection delay is lower, and the transmission capacity is larger.
Furthermore, the server in the prior art needs to store the face data and account data of the public transportation owner, which requires perfect and accurate data collection work in the early stage of the operation of the system, and it is known that 100 ten thousand all-purpose cards of public transportation are cumulatively issued only in 2008 in the public city, and 1000 ten thousand of public transportation cards are broken through by the current issued public transportation cards, so that the corresponding face data amount of the public transportation cards is very huge. In general, in order to meet the face recognition requirement, a minimum 256-gray-level picture is required for a picture to be put in storage of data in a face recognition database; the size of the image data is larger than 70 × 80 pixels, so that each person needs several images with different sizes from tens to hundreds of K, if each person needs 1M of capacity, nearly ten million people in the market need 10P bytes, sometimes living body detection samples need to be included, the data volume of the required samples is larger, meanwhile, for high reliability of the data, data backup needs to be carried out, the required storage space is larger, and the problem of data consistency is also generated. Therefore, the prior art puts high demands on data storage, reading, reliability and consistency. In the embodiment of the invention, the human face data is only used as a unique identifier in most processes, and the human face data does not need to be stored. Furthermore, a camera can be arranged at the bus stop, the shot face data are sent to the vehicle-mounted terminal, and the vehicle-mounted terminal shoots when a user gets on the bus, so that more face data can be obtained on one hand, and on the other hand, the camera part arranged at the bus stop can replace the function of the vehicle-mounted camera, so that the number of face images shot by the vehicle-mounted terminal is reduced, and the getting-on speed of passengers is further improved; in addition, time is sufficient, uploading and online recognition of a large number of faces in a short time of getting on or off the bus are not needed, and concurrency pressure of the central data server is further reduced.
In addition, the vehicle-mounted terminal can send the face data to the server after acquiring the face data, and the server returns a fee deduction signal to the vehicle-mounted terminal, so that the process requires low delay. Moreover, the public transport system transports millions of passengers every day, and mainly focuses on the peak period of morning and evening, so that the face image database is required to have the characteristics of high concurrency and low delay; and the traffic of people is great when getting on the bus, if delay is very high, influence efficiency easily, moreover, according to knowing that present face identification technique will be used in the small range scene of like attendance, entrance guard with miniature database local deployment, will be used in APP authentication etc. and to delaying relatively insensitive scene, above two kinds of scenes do not involve high concurrency condition. Moreover, the failure rate of APP remote face authentication is high, if the APP remote face authentication is successful, the APP remote face authentication can be identified again, and on a bus, the passing efficiency is influenced once the APP remote face authentication fails; especially, the face recognition of the old people is always a technical problem of face recognition, and the failure risk is further increased, so that the low-delay accurate response of a face image remote database under a high concurrency condition cannot be realized under the prior art, and the embodiment of the invention mainly performs face recognition and fee deduction calculation locally and is easy to realize from software and hardware.
In addition, in the prior art, when the face is brushed during the process of getting on or off the bus, the vehicle-mounted terminal needs to be connected with the server in real time, and the face and the account number of all people need to be stored in the server, so that the requirement on complete and accurate data collection in the early stage is required, and in addition, many buses belong to third-party operation and do not have privacy information management quality, so that the face recognition technology is relatively difficult to apply, and the account number needs to be registered and bound with a user; the operation is complicated. At present, most solutions are completed by depending on a smart phone in order to promote the sectional payment. However, it is reported that "in our country, the number of elderly people over 60 years old is 2.49 hundred million, and the internet penetration rate is less than 2, that is, the ratio of the elderly people in China using smart phones is less than 20%. Furthermore, designers of intelligent equipment are mostly middle-aged and young people with normal perceptibility, which looks like an intelligent screen with simple interaction, and many old people can encounter obstacles in various aspects such as vision, operation, flow and the like. In addition, for the old people who are used to the visible paper money, the money is not safe when being placed in the mobile phone, and the acceptance of the old people to virtual matters such as the internet is generally low due to phishing and the safety frequency of the mobile phone. Therefore, most of the old people have great distrust on the internet, and further the penetration rate to the smart phone is influenced. However, in the prior art, the old needs to be equipped with a smart phone and perform a series of operations on the smart phone, and for the reasons mentioned above, it is a great challenge for the old to take a bus based on the prior art, and therefore, the application of the prior art is not friendly to the old. By applying the embodiment of the invention, the old people can swipe the card once, but the current one-time swiping of the card is rated to deduct the fee, and the one-time swiping of the card is realized by using a series of software and hardware deployment on the basis of not changing the conventional payment mode which is already used by the old people, so that the method is more friendly to the old people.
Furthermore, some public transport cards are provided with a plurality of public transport cards, some public transport cards are used by family members randomly, and if face matching or family member relation matching is not performed in time, the problem that the public transport cards cannot be paid is caused when face payment in the prior art is used in the using mode. In the embodiment of the invention, the face data of the cardholder is only used as the unique identifier, the APP does not need to be downloaded, the card does not need to be transacted, the registration in the server is not needed in advance, and the problems can not be caused, so the stability is better.
Finally, the first fee deduction data in the embodiment of the invention are all synchronized with the central data server, and the structured face data of the passenger can be written into the first fee deduction data, so that the central data server can have consumption records of who, when and where the card is consumed, thereby being more beneficial to fund safety and being beneficial to flow regulation of epidemic situation prevention and control to a certain extent.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
Fig. 1 is a schematic flowchart of a non-sensory interaction method based on the internet of vehicles and edge computing according to an embodiment of the present invention, and as shown in fig. 1, the method is preferably applied to a vehicle-mounted terminal, and the method includes:
s101: obtain the information of punching the card that current passenger got on the bus to obtain the first facial data when current passenger got on the bus, wherein, facial data includes: one or a combination of a facial optical image, a depth map.
In the first embodiment of this step, when the current passenger a gets on the vehicle, a facial picture of the current passenger may be taken by using a vehicle-mounted camera provided at the boarding door, and the facial picture may be used as the first facial data of the current passenger; or the infrared laser radar is used for scanning the face of the current passenger, and the scanned point cloud data is also added into the first face data, so that the face recognition accuracy is improved. Or the point cloud data of the face of the current passenger A is acquired by using equipment with depth information acquisition, such as a structured light camera, a flight time camera and the like, so as to acquire the depth information of the face of the current passenger A and improve the capability of the system for resisting attack of a color printing simulation mask. Furthermore, the high-precision point cloud data of the face of the current passenger A can be acquired by using a multi-line laser radar or a structured light camera, the facial photo obtained by matching the multi-line laser radar or the structured light camera acquires the detail data of the face of the current passenger A, and therefore the face identification precision of the current passenger A is improved, and the capability of the system for resisting the attack of a 3D mask is improved. Then after the current passenger A gets on the bus, the card swiping action is required to be executed when the current passenger A passes through the card swiping machine, and the card swiping machine can read the card swiping information of the current passenger A; then, the step S102 is executed to perform binding processing on the photographed first face data of the current passenger a and the card swiping information of the current passenger a.
In the second embodiment of this step, or an on-board camera is installed on the card swiping machine, when the current passenger a swipes the card, the first face data of the current passenger a is photographed, and then the step S102 is executed to bind the card swiping information of the current passenger a with the first face data thereof.
In a third embodiment of this step, after the current passenger a enters the shooting range of the vehicle-mounted camera, the face data of the current passenger a and/or the point cloud data of the face of the current passenger a may be shot multiple times to obtain multiple images, and then the set of the multiple images is used as the first face data corresponding to the current passenger a.
S102: and binding the card swiping information with the first face data information.
In practical application, the face feature data may be extracted from the first face data, the card number swiped by the card swiping information is used as a key, and the face feature data, the balance data, the train number data, the timestamp and the like are used as values to generate the structured key value pair.
It can be understood that the more types of values included in the structured key value pair are more beneficial to the operation of the system, and certainly, the types of data can be configured by system operation and maintenance personnel according to actual requirements, so that the system of the embodiment of the invention has higher expandability and flexibility.
S103: the method comprises the steps of obtaining second face data of a current passenger when the passenger gets off the vehicle, comparing the second face data with the first face data, generating corresponding first deduction information under the condition that the second face data and the first face data are matched, and sending the first deduction information and the face data of the current passenger to a receiving end, so that the receiving end sends the first deduction information to a next card swiping device used for the current passenger to swipe the card to receive the first deduction information.
Illustratively, when the vehicle reaches the destination of the current passenger a, the door is opened, the passenger starts to get off the vehicle, and when the current passenger a passes through the photographing range of the camera provided at the place where the door is got off, the camera photographs the second face data of the current passenger a. It is understood that the arrangement, type and number of the cameras provided at the lower door may be equal to the arrangement, type and number of the on-vehicle cameras at the upper door, so that the number, type and shooting angle of the images included in the second face data shot at the lower door are similar to the number, type and shooting angle of the images included in the first face data shot at the upper door as much as possible. This provides two advantages, firstly, the data of the current passenger a is captured from three dimensions of the number and the type of the images and the capturing angle, so that the accuracy of identifying the current passenger a is improved, especially for the elderly. The facial skin wrinkles of the elderly are accumulated due to the reduction of facial fat, so that part of facial features are covered, the similarity degree between the old faces is high, and if the face of the elderly is compared by using an image at one shooting angle, misjudgment is easily caused, so that the face images of the elderly are compared from multiple dimensions. Secondly, the dimensionality of the images shot at the two positions is the same, so that the image mapping conversion operation can be avoided in the comparison process, the calculated amount is reduced, the comparison speed is increased, and the phenomenon of congestion during getting off the vehicle is avoided.
After the second face data of the current passenger a is acquired, the vehicle-mounted terminal-1 compares the second face data with the first face data, and if the second face data and the first face data are the same or the similarity degree reaches a preset threshold value, it is determined that the passenger corresponding to the first face data and the passenger corresponding to the second face data are the same person, and it is determined that the current passenger a gets off the vehicle. Then, fee deduction processing is carried out on the card corresponding to the first face data: and acquiring the number of stations taken by the current passenger A or the mileage taken by the current passenger A according to the station on which the current passenger A gets on and the station on which the current passenger A gets off, and further calculating first deduction information corresponding to the current passenger A.
Because the card that current passenger A carried can not be when getting off the car the card of punching the card, simultaneously the camera of door department of getting off can not network in real time and carry out the linkage and deduct the expense yet, consequently, can not carry out the processing of deducting the expense to current passenger A's card when current passenger A gets off the car. In order to realize fee deduction for the card of the current passenger A, the vehicle-mounted terminal-1 transmits the first fee deduction information, the first face data of the current passenger A and/or the second face data of the current passenger A to a receiving end, or transmits the first fee deduction information, the first face data of the current passenger A and/or the second face data of the current passenger A to a relay device, and the relay device transmits the first fee deduction information, the first face data of the current passenger A and/or the second face data of the current passenger A to the receiving end. In practical applications, the receiving end is usually a wireless transceiver device disposed on the platform, and data intercommunication is realized between the receiving end and the vehicle-mounted terminal in a secure and trusted manner.
In order to further reduce the calculation amount of face recognition, the face features respectively contained in the first face data and the second face data are not recognized; and only comparing the image similarity of the first face data and the second face data. Because the number of passengers in the same vehicle is not more than 200, the number of images of the first face data and the second face data is limited, the probability that the similarity degree of the first face data and the second face data is higher is lower, and the set comparison rule can also ensure higher accuracy. In the prior art, two face recognitions are needed, namely, the shot images are respectively compared with the images in the database, so that the calculation amount of the embodiment of the invention is smaller. In addition, the embodiment of the invention locally compares a smaller number of images, so that the similarity probability is reduced more, and the number of processed objects is smaller, thereby having higher speed.
It is understood that, for passengers other than the current passenger a, such as the passenger B, are processed according to the above-mentioned flow, and the embodiment of the present invention is not described herein again.
Example 2
Based on embodiment 1, after the task of the vehicle-mounted terminal-1 in the interactive system is completed, the specific process for updating the first deduction information for the receiving end is as follows:
after receiving the first deduction information sent by the vehicle-mounted terminal-1 and the first face data of the current passenger A and/or the second face data of the current passenger A, the receiving end firstly judges that the current passenger A cannot be transferred after getting off the vehicle. When the current passenger A changes the passenger A at the same station, the fee deduction updating is realized by the card swiping equipment contained in the vehicle-mounted terminals of other vehicles entering the station; when the current passenger A changes the passenger from the different station, after the receiving end of the get-off platform synchronizes the first deduction information to other receiving ends of the platform changed by the current passenger A, the deduction updating is realized by the card swiping equipment contained in the vehicle-mounted terminals on the vehicles of other platforms; if the passenger does not transfer the card, the card swiping device when the current passenger A uses the card next time can request the first fee deduction information from the central data server to realize fee deduction updating.
In a first aspect, a specific method flow for identifying the co-stop transfer and updating the deduction fee is as follows: after the current passenger A gets off the train, if the current passenger A is transferred from the same station, the current passenger A can stay at the station until the target vehicle arrives, and the stay time is longer. Based on this, the platform camera included in the receiving end can shoot the face data of all people on the platform, then the first face data and/or the second face data of the current passenger A are compared with the face data, and if the comparison result is positive, the current passenger A is on the platform. After the preset time length, if the current passenger A is still on the platform, the current passenger A is judged to be the passenger who transfers from the same station. At this time, when other vehicles enter the radiation range of the signal transmitted by the receiving end arranged on the platform, the receiving end transmits the first fee deduction information to the vehicle-mounted terminals of the other vehicles. In consideration of the possibility that the current passenger a gets off the vehicle and then immediately transfers the vehicle to another vehicle in the actual situation, in the embodiment of the present invention, the receiving end may synchronize the first deduction information to another vehicle in the station immediately after receiving the first deduction information. In practical applications, a plurality of wireless data exchange interfaces may be disposed on one station platform to provide for data interaction operations of a plurality of vehicles. The wireless data exchange interfaces, the cameras on the platform and the central processing unit form a receiving end together.
After the current passenger a gets off the train, the current passenger a does not transfer other vehicles immediately, or does not stay at the platform for a time period longer than a preset time period, so the current passenger a may transfer the current passenger a from the different station or does not need to transfer the current passenger a. In order to judge whether the current passenger A is a transfer or does not need to be transferred, the embodiment of the invention is additionally provided with the following steps:
and the central data server reads the corresponding transfer interval in the card riding record or the corresponding transfer interval in the riding record matched by the first face data of the current passenger A. Determining the geographical range of passenger transfer according to the distance; then, the stations within the geographic range are determined, and the receiving ends on the stations where the current passenger A gets off are synchronized to other receiving ends. When other receiving terminals in the geographic range recognize the arrival behavior of the current passenger A, the passenger is judged to be transferred from different stations, the first fee deduction information of the current passenger A is synchronized to other vehicles entering the station by the other receiving terminals, and when the other vehicles swipe the card on the current passenger A, the information of the card is recognized, and then the actual balance of the card is updated according to the first fee deduction information. The other vehicle then executes step S101 in the embodiment of the present invention. The data synchronization between the receiving ends is carried out, and compared with the situation that all the receiving ends send and request data to the central data server, the data synchronization method can reduce the reading and writing pressure of the central data server, and further can free up bandwidth for other tasks with higher requirements on real-time performance.
After the receiving end on the platform where the current passenger a gets off is synchronized to the other receiving ends for a set time interval, the current passenger a does not enter the station, which indicates that the current passenger a does not need to transfer. At this time, the fee deduction is not realized for the current passenger A, and the receiving end synchronizes the corresponding first face data and the first fee deduction information to the central data server. So that the central data server generates second fee deduction information of the card. The first deduction information and the second deduction information may be structured text data including: the card number, the face feature data, the last deduction amount, the actual balance information and the like, and text data are easier to transmit compared with image data, and the requirement on bandwidth is lower. When the card used by the current passenger A is swiped by other card swiping equipment, the card swiping equipment firstly requests the actual balance information of the card from the central data server, the central data server returns second fee deduction information, and the second fee deduction information comprises the actual balance information of the card, so that the card swiping equipment updates the card according to the second fee deduction information. It should be emphasized that the card swiping device in the embodiment of the present invention may be a card swiping device installed at a vehicle door of a vehicle, or may be a card swiping device installed in a convenience store, a supermarket, a door access, or other places supporting the card.
Example 3
Based on embodiment 2 of the present invention, in order to enable the receiving end of the platform to obtain the second fee deduction information for the passenger in advance, the loophole caused by the corresponding second fee deduction information does not exist in the receiving end when the passenger gets on the bus and swipes the card, and the passenger does not write the actual balance last time and rides for the first time in the day is avoided. When a passenger enters a shooting range of a camera of a platform, a receiving end shoots face data of the passenger by using the camera, the face data is uploaded to a central data server, the central data server matches the face data with the face data stored in a database in advance, then inquires cards used by the passenger, second fee deduction information corresponding to all the cards and containing actual balance information is returned to the receiving end, the receiving end synchronizes the second fee deduction information to an incoming vehicle, when the passenger gets on the vehicle, the actual balance is written into the cards, and then the cards are bound with the first face data. Therefore, on one hand, the missed deduction can be avoided, on the other hand, the actual balance information in the card can be updated timely, and malicious riding of the current passenger A when the balance in the card is insufficient can also be avoided.
It is emphasized that the actual balance is the balance of the card calculated by the central data server after the last ride of the user after deducting the last fare. The actual balance may be different from the actual balance stored in the card, and the difference is the deduction amount in the first deduction information of the last bus taking. However, as long as the card holder, that is, the current passenger a swipes the card, the card swipe will write the actual balance obtained by obtaining the second fee deduction information of the card from the receiving end or the central data server into the card, and therefore, although there is a difference between the two data, the loophole that the current passenger a can utilize will not be caused.
Further, in order to further avoid the loophole and realize double insurance, when the central data server detects that the balance in the card of the current passenger A is lower than the set limit, the central data server sends out a balance shortage reminder to the corresponding mobile phone number. Or, the central data server can also obtain corresponding travel data according to the card information, further obtain a historical maximum deduction value corresponding to the card information, judge whether the historical maximum deduction value is less than or equal to the actual balance, and if the historical maximum deduction value is less than the actual balance, show that the card holder can continue to take the bus; if the balance is larger than the actual balance, the card holder can not continue to take the bus, and a balance shortage reminder is sent to the corresponding mobile phone number. And adding the judgment result into the second fee deduction information and sending the second fee deduction information to a receiving end arranged on the platform, wherein the receiving end sends the judgment result to the vehicle-mounted terminal when the vehicle enters a signal radiation range at the vehicle-mounted terminal, so that after the information of the card is identified when the current passenger A gets on the vehicle for swiping the card, the actual balance of the card can be updated according to the second fee deduction information, and a reminder of insufficient balance is sent. In practical applications, the historical maximum deduction value may be replaced by the whole road vehicle fee, or the historical maximum deduction value may be replaced by the maximum deduction value of the card in the last year, or the historical maximum deduction value may be replaced by the mode of all the deduction values of the card, or the historical maximum deduction value may be replaced by the historical maximum deduction value of the card for the road vehicle, or the historical maximum deduction value may be replaced by the maximum deduction value of the card in the last year for the road vehicle. In the embodiment of the invention, the setting mode of the specific numerical value is not limited, and the vehicle operator can set the numerical value according to the actual requirement. By applying the embodiment of the invention, the insurance margin is preset in the fee deduction rule, so that double insurance of malicious card swiping or malicious riding of passengers by utilizing the loophole of the fee difference can be realized.
Furthermore, the receiving terminals need to synchronize the received first face data and the first fee deduction information to the central data server, so that the central data server becomes second fee deduction information for the next card swiping of the card, although the synchronization process can be performed in real time, the read-write load of the central data server is increased, and therefore flexible configuration of the load can be performed according to actual conditions. When the read-write bandwidth of the central data server is enough, the data interaction between the receiving ends is not carried out any more, and the second fee deduction information is directly obtained from the central data server instead, so that the embodiment of the invention can flexibly adapt to the read-write bandwidth of the central data server, and the robustness of the system is improved. Furthermore, two central data servers can be deployed, wherein one central data server is used for data synchronization, the other central data server is used for high-real-time task communication, and the two central data servers realize rapid data comparison through a high-speed broadband so as to ensure the consistency of data. In addition, the second fee deduction information can be structured data consisting of card identification information, actual balance information and first face data; it is also possible to have structured data consisting of only card identification information and actual balance information.
By applying the embodiment 2 of the invention, the current passenger A can be transferred on the same station, transferred on different stations and updated in the actual balance without the transfer condition, thereby avoiding the situation of inconsistent data.
Example 4
In embodiment 4 of the present invention, on the basis of embodiment 1, before the step S101, the following steps are added:
s104 (not shown in the figure): and acquiring second fee deduction information of the transfer passenger within the signal entering range of the vehicle-mounted terminal.
When the vehicle to be taken by the current passenger A enters the station, the vehicle enters a signal radiation range of a receiving end arranged on the station along with the advance of the vehicle, and then the receiving end sends second fee deduction information of the transfer passenger to a vehicle-mounted terminal of the vehicle.
The second fee deduction information may be obtained by the receiving end from other receiving ends, or may be obtained by the receiving end from the central data server.
After the current passenger A gets on the bus, card swiping equipment on the bus can acquire card swiping information of the current passenger getting on the bus and match the card swiping information with card information in the second fee deduction information; if the two are matched, the current passenger A is a transfer passenger or a passenger who has not written the actual balance last time and takes a bus for the first time on the same day, and then the amount of money in the corresponding card is changed according to the second fee deduction information; then, the step S102 in embodiment 1 is executed to perform binding processing on the card swiping information and the first face data information. If the two are not matched, the current passenger A is not a transfer passenger, and the step of binding the card swiping information and the first face data information is directly executed.
It should be emphasized that the second deduction information may be formed corresponding to the riding behavior of the current day, or may be formed corresponding to the deduction behavior that is generated when the passenger does not take the ride after taking the ride of the previous day, that is, the transfer referred to in the embodiment of the present invention is to replace a ride of a vehicle, and is not limited to the ride of the same day.
In addition, under the condition that the receiving end cannot acquire the second fee deduction information, the card used by the current passenger a may be used for the first time, so that the central data server does not have corresponding actual credit information, or the receiving end, which is caused by short card swiping time, cannot acquire the real-time balance from the receiving end or the central data server until the receiving end recognizes the card number. The embodiment of the invention prompts that the card is not successfully swiped to please swipe the card again after the card is swiped for the first time, meanwhile, the vehicle-mounted terminal sends the serial number of the card to the central data server with the highest priority, the central data server directly realizes the return of the second fee deduction information by the communication with the highest priority, and the process is finished in the process of twice swiping the card by passengers. Therefore, data interaction with the central data server is greatly reduced, and the functions can be easily realized by matching with a 5G communication technology. If the balance in the card is larger than the maximum deduction amount of the line after the second deduction information is deducted from the passenger card, the card swiping success is judged, and the step S101 is executed.
In practical application, by applying the embodiment of the invention, the real balance of the card can be timely and synchronously avoided from loopholes.
Further, the acquiring the first facial data of the current passenger when getting on the vehicle includes:
comparing the first facial data with first facial data of other passengers stored in the vehicle-mounted terminal to obtain similarity;
acquiring additional features for the first face data when the similarity is greater than a preset threshold, wherein the additional features include: one or a combination of other facial features, clothing features, and posture features.
In order to improve the recognition degree of the current passenger A, the half-length picture of the passenger is also shot, the half-length picture of the passenger is added into the first face data, so that more features are provided when the face data information is matched, and the matching accuracy of the face data when the current passenger A gets off the vehicle is improved. In practical application, the bust photos of the passengers can be taken firstly, then the comparison is carried out, if the similarity is larger than or equal to the preset threshold value, the bust photos are reserved, if the similarity is smaller than the preset threshold value, only the face area is compared when the first face data is compared with the second face data, and the non-face area is also reserved for comparison of other passengers getting on the bus at the next station.
By applying the embodiment of the invention, because part of passengers can change the facial structure due to factors such as age, diseases, injuries, makeup, beauty and the like, especially for the elderly, the facial recognition of the old faces is always a difficult problem in the technical field of facial recognition, and the embodiment of the invention supplements more data aiming at the face data, so that the accuracy of passenger recognition can be improved.
