[0002] License plate recognition is an application of computer video image recognition technology in vehicle identification; in parking lot management, license plate recognition technology is also the main means of identifying vehicle identity, which can realize automatic identification of vehicle identity.

[0003] When the current parking lot entrances and exits recognize license plate information, there may sometimes be a deviation between the license plate information recognized at the entrance and the actual license plate information due to dust, mud and other debris adhering to the license plate; and when the vehicle leaves the parking lot from the exit, due to external factors such as rain during parking, if the dust and mud on the license plate are brushed off, it may cause the license plate information recognized at the exit to be difficult to match the license plate information recognized at the entrance, and the vehicle may be unable to pay and drive out normally. Summary of the invention

[0004] In order to help improve the problem that parking lot exit license plate information is difficult to match with entrance license plate information, the present application provides a license plate information processing method and system.

[0005] In a first aspect, the present application provides a license plate information processing method, which adopts the following technical solution: the method comprises: obtaining entry license plate information, the entry license plate information comprising graphic data of the license plate;

[0006] Processing the graphic data of the entry license plate information according to a preset equivalent correspondence relationship and generating an entry identification data packet, wherein the entry identification data packet includes a plurality of entry similar license plate information corresponding to the entry license plate information;

[0008] Processing the graphic data of the exit license plate information according to a preset equivalent correspondence relationship and generating an exit identification data packet, wherein the exit identification data packet includes a plurality of exit similar license plate information corresponding to the exit license plate information;

[0009] The exit identification data packet corresponding to the current exit license plate information is compared with all the entry identification data packets. If a certain entry identification data packet is associated with the current exit identification data packet, the payment information is queried and sent according to the associated entry identification data packet and exit identification data packet.

[0010] Through the above technical scheme, after the entry license plate and exit license plate are obtained, a number of similar license plate information corresponding to the entry or exit license plates are generated through a preset equivalent correspondence relationship. When a vehicle requests to exit, the specific acquired license plate information is not compared, but the generated several exit similar license plate information and several entry similar license plate information are compared; thereby reducing the possibility that the entrance and exit license plate information is difficult to match due to errors such as mud and sand obstruction between entry and exit; and improving the success rate of the parking lot in identifying and comparing license plate information.

[0011] Preferably, after obtaining the entry license plate information, the method further includes:

[0012] Acquire color information of the entry license plate, the color information including a plurality of pre-divided recognition areas and color data corresponding to different recognition areas;

[0013] Comparing the acquired color information of the entry license plate with the preset color information of the standard license plate to obtain an identification area with color data difference;

[0014] The processing of the graphic data of the entry license plate information according to the preset equivalent correspondence relationship and generating an entry identification data packet includes:

[0015] According to the preset equivalent correspondence relationship, the graphic data corresponding to the identification area with color data difference is processed to generate an entry identification data packet.

[0016] Through the above technical solution, the license plate color is identified in advance, so that when the entry license plate information is processed according to the preset equivalent relationship, only the graphic data of the license plate information corresponding to the identification area with color data difference can be processed, thereby reducing the amount of data in the entry identification data packet and improving the recognition efficiency when the vehicle exits.

[0017] Preferably, if a certain entry identification data packet is associated with a current exit identification data packet, it includes:

[0018] If a plurality of similar entry license plate information in a certain entry identification data packet and a plurality of similar exit license plate information in a current exit identification data packet have at least one identical license plate information, then it is determined that the entry identification data packet is associated with the current exit identification data packet;

[0019] Otherwise, it is determined that all of the entry identification data packets are not associated with the current exit identification data packet.

[0020] Through the above technical solution, as long as there is at least one identical license plate information between the entry identification data packet and the exit identification data packet, it is determined that the entry identification data packet and the exit identification data packet are generated based on the same license plate information, further improving the success rate of the parking lot in identifying and comparing the license plate information.

[0021] Preferably, after determining that all the entry identification data packets are not associated with the current exit identification data packet, the method further includes:

[0022] Acquire the exit license plate information again, wherein the exit license plate information includes the graphic data of the license plate;

[0023] According to the preset equivalent correspondence relationship, the graphic data of the exit license plate information acquired again is processed and a secondary confirmation data packet is generated, wherein the secondary confirmation data packet includes a plurality of exit similar license plate information corresponding to the exit license plate information;

[0024] Compare the secondary confirmation data packet with all the admission identification data packets, and if a certain admission identification data packet is associated with the secondary confirmation data packet, query and send payment information according to the associated admission identification data packet and secondary confirmation data packet;

[0025] Otherwise, it is determined that all the entry identification data packets are not associated with the secondary confirmation data packet.

[0026] Through the above technical solution, the license plate information that failed to be associated is recognized and compared again, which reduces the possibility of association failure caused by light influence or errors in equivalent processing during the identification process, thereby further improving the success rate of the parking lot in recognizing and comparing the license plate information; if the association still fails, the staff will be notified in time to handle it so that the vehicle can leave the parking lot in time.

[0027] Preferably, before obtaining the entry license plate information, the method further includes:

[0028] Acquire entry vehicle picture information, wherein the entry vehicle picture information includes an entry photo taken when the vehicle enters the venue;

[0029] storing the acquired entry photo in an entry image database;

[0030] After determining that all the entry identification data packets are not associated with the secondary confirmation data packet, the method further includes:

[0031] Acquire exit vehicle picture information, wherein the exit vehicle picture information includes an exit photo taken when the vehicle exits;

[0032] If the exit photo matches an entry photo in the entry image database, the payment information is queried and sent according to the matching entry photo and exit photo; otherwise, a prompt message related to the matching failure is sent to the staff's smart device.

[0033] Through the above technical solution, when the license plate information association fails, the vehicle is identified by comparing the vehicle entry photo and exit photo, which further reduces the possibility of vehicle identification failure, thereby further improving the parking lot's success rate in identifying and comparing license plate information.

[0034] Preferably, after sending the prompt information related to the matching failure to the smart device of the staff, it also includes:

[0035] The exit license plate information obtained twice, the exit identification data packet generated according to the preset equivalent correspondence relationship, and the secondary confirmation data packet are recorded and packaged to generate an abnormal identification data packet;

[0036] Adjusting the anomaly identification data packet to the anomaly database;

[0037] Regularly send the anomaly identification data packets in the anomaly database to the smart devices of the backend operation and maintenance personnel.

[0038] Through the above technical solution, when the association still fails after the second identification and comparison, the exit license plate information obtained during the comparison process, the exit identification data packet generated according to the preset equivalent correspondence relationship, and the secondary confirmation data packet are sent to the backend operation and maintenance personnel, so that the backend operation and maintenance personnel can update and optimize the preset equivalent correspondence relationship based on the information related to the association failure.

[0039] Preferably, after querying and sending the payment information according to the mutually associated entry identification data packet and exit identification data packet, the method further includes:

[0040] Adjusting the associated entry identification data packet to a temporary database and no longer participating in subsequent comparisons;

[0041] The admission identification data packets in the temporary database are deleted regularly.

[0042] Through the above technical solution, the associated entry identification data packet is removed, so that when the license plate information of the subsequent vehicles leaving the venue is compared, one entry identification data packet comparison step can be reduced, thereby further improving the recognition efficiency when the vehicle leaves the venue.

[0048] The exit data comparison module is used to compare the exit identification data packet corresponding to the current exit license plate information with all the entry identification data packets. If a certain entry identification data packet is associated with the current exit identification data packet, the payment information is queried and sent according to the associated entry identification data packet and exit identification data packet.

[0049] Through the above technical scheme, after the entry license plate and exit license plate are obtained, a number of similar license plate information corresponding to the entry or exit license plates are generated through a preset equivalent correspondence relationship.

Detailed implementation manners

[0065] The following further describes the present application in detail with reference to the Figure 1-7 accompanying drawings.

[0066] An embodiment of the present application discloses a license plate information processing method, which is based on a parking lot intelligent control system. The parking lot intelligent control system can identify and process the license plate information of vehicles entering and exiting the parking lot. After the information of the exiting vehicle and the entering vehicle is associated and matched, the parking lot intelligent control system correspondingly queries the payment information of the current exiting vehicle and displays the amount to be paid and the payment method. The payment method can be a payment QR code or manual payment, etc.; and after the vehicle owner completes the payment, the gate is opened for release.

[0067] As Figure 1 shown, the method includes the following steps:

[0068] S10, acquiring picture information of the entering vehicle.

[0069] Among them, the picture information of the vehicle includes the entrance photo taken when the vehicle enters the parking lot. Specifically, a camera is used to take a photo of the vehicle requesting to enter the parking lot to obtain the photo when the vehicle enters the parking lot.

[0070] S11, storing the entrance photo in the entrance image database.

[0071] Specifically, the acquired entrance picture is stored in the entrance image database, and at the same time, the entrance pictures in the entrance image database that reach the storage period are regularly deleted; for example, the entrance pictures with a storage period reaching one week are deleted.

[0072] S12, acquiring entrance license plate information.

[0073] Specifically, license plate recognition technology is used to recognize the license plate information of the vehicle requesting to enter the parking lot. The acquired entrance license plate information includes the graphic data of the license plate. The graphic data of the license plate is information such as the characters, letters, and numbers on the license plate. For example: "Yue B·630I1".

[0074] S13, acquiring the color information of the entrance license plate.

[0075] Among them, the color information includes several pre-divided recognition regions and the color data corresponding to each recognition region; for example, in combination with Figure 2 , the license plate information is pre-divided into seven recognition regions, region 1 to region 7. Each recognition region corresponds to a piece of graphic data and color data. For example, region 6 corresponds to the graphic data "I", and the color data corresponding to region 6 is that the place of the graphic data "I" is white, and the area outside the graphic data "I" is blue.

[0076] S14. Compare to obtain the recognition regions with color differences.

[0077] Specifically, compare the color information of the incoming license plate obtained with the preset standard license plate color information to obtain the recognition regions with different color data; for example, if a part of region 6 in the incoming license plate information is blocked by sediment, the blocked area will be recognized as gray or black, then the recognition region with different color data obtained after comparison is region 6.

[0078] S15. Generate an incoming recognition data packet.

[0079] Specifically, according to the preset equivalent correspondence relationship, process the graphic data corresponding to the recognition regions with different color data in the incoming license plate information, and generate an incoming recognition data packet. The incoming recognition data packet includes several incoming similar license plate information corresponding to the incoming license plate information; the corresponding preset equivalent relationship is the equivalent relationship of graphic data that are similar in shape, such as the three of "1, I, and T" constitute the equivalent relationship of graphic data. Based on the foregoing example, if the license plate information is "Yue B·630I1" and the recognition region with different color data is region 6, then after processing, similar license plate information such as "Yue B·63011", "Yue B·630I1", or "Yue B·630T1" will be formed;

[0080] If the color information of the incoming license plate obtained is consistent with the preset standard license plate color information, then according to the preset equivalent correspondence relationship, process all the image data in the incoming license plate and generate an incoming recognition data packet.

[0081] S16. Obtain the outgoing license plate information.

[0082] Specifically, use license plate recognition technology to recognize the license plate information of the vehicle requesting to leave the parking lot. The recognized outgoing license plate information obtained includes the graphic data of the license plate.

[0083] S17. Generate an outgoing recognition data packet.

[0084] Specifically, according to the preset equivalent correspondence, the graphic data of the outgoing license plate information is processed to generate an outgoing recognition data packet, and the outgoing recognition data packet includes several outgoing similar license plate information corresponding to the outgoing license plate information; for example, for the license plate information "Yue B·630I1", the preset equivalent relationship may include: "1 and I" and "0 and C", and after processing, similar license plate information such as "Yue B·63011", "Yue B·630I1", or "Yue B·63CI1" will be formed.

[0085] S18. Determine whether the current outgoing recognition data packet is associated with the incoming recognition data packet.

[0086] Specifically, compare the outgoing recognition data packet corresponding to the current outgoing license plate information with all the incoming recognition data packets. The current outgoing license plate information is the vehicle information corresponding to the vehicle currently applying to drive out of the parking lot; if there is at least one identical license plate information between several incoming similar license plate information in a certain incoming recognition data packet and several outgoing similar license plate information in the current outgoing recognition data packet, it is determined that the incoming recognition data packet is associated with the current outgoing recognition data packet and S20 is executed, otherwise it is determined that all the incoming recognition data packets are not associated with the current outgoing recognition data packet and S19 is executed; for example, the similar license plate information in a certain incoming recognition data packet is: "Yue B·63011", "Yue B·630I1", and "Yue B·630T1", and the similar license plate information in the outgoing recognition data packet is: "Yue B·63011", "Yue B·630I1", and "Yue B·63CI1"; since both have the identical license plate information "Yue B·63011" and "Yue B·630I1", it is determined that this incoming recognition data packet is associated with the current outgoing recognition data packet.

[0087] S19. Perform a secondary confirmation on the outgoing license plate information.

[0088] As Figure 3 shown, where S19 includes the following four sub-steps:

[0089] S191. Obtain the outgoing license plate information again.

[0090] Specifically, use the license plate recognition technology again to recognize the license plate information of the vehicle requesting to drive out of the parking lot, and the recognized outgoing license plate information obtained includes the graphic data of the license plate.

[0091] S192. Generate a secondary confirmation data packet.

[0092] Specifically, according to the preset equivalent correspondence relationship again, the graphic data of the license plate information for departure is processed to generate a secondary confirmation data packet, and the secondary confirmation data packet includes a number of departure similar license plate information corresponding to the license plate information for departure; for example, due to factors such as light, the license plate information "Yue B·630I1" may form "Yue B·83011" after being photographed again, resulting in differences in the similar license plate information generated again.

[0093] S193, determine whether the secondary confirmation data packet is associated with the entry recognition data packet.

[0094] Specifically, compare the secondary confirmation data packet with all the entry recognition data packets. If there is at least one identical license plate information between a number of entry similar license plate information in a certain entry recognition data packet and a number of departure similar license plate information in the secondary confirmation data packet, it is determined that the entry recognition data packet is associated with the secondary confirmation data packet and S194 is executed; otherwise, it is determined that all the entry recognition data packets are not associated with the secondary confirmation data packet, and S30, S31, and S32 are executed synchronously.

[0095] S194, query and send payment information according to the secondary confirmation data packet.

[0096] Specifically, according to the associated entry recognition data packet and secondary confirmation data packet, query the corresponding payment information between the entry recognition data packet and the secondary confirmation data packet, and send the payment information and payment method to a display area such as an exit display screen for display, so that the vehicle owner can pay and leave the venue.

[0097] S20, query and send payment information according to the departure recognition data packet.

[0098] Specifically, according to the associated entry recognition data packet and departure recognition data packet, query the corresponding payment information between the entry recognition data packet and the departure recognition data packet, and send the payment information and payment method to a display area such as an exit display screen for display, so that the vehicle owner can pay and leave the venue.

[0099] S21, process the associated data packets.

[0100] Specifically, adjust the associated entry recognition data packet to the temporary database and no longer participate in subsequent comparisons, so that when subsequent vehicles leaving the venue are compared, the already associated entry recognition data packets can be skipped, thereby improving the comparison efficiency of subsequent vehicles leaving the venue; at the same time, regularly delete the entry recognition data packets adjusted to the temporary database. For example, delete the entry recognition data packets stored in the temporary database for 7 days.

[0101] S30, compare the vehicle departure photos.

[0102] like Figure 4 As shown, S30 specifically includes the following three sub-steps:

[0103] S301, obtaining the image information of the vehicle leaving the site.

[0104] The exit vehicle picture information includes an exit photo taken when the vehicle exits the parking lot; specifically, a camera is used to take a photo of the vehicle requesting to exit the parking lot to obtain the photo of the vehicle when it exits the parking lot.

[0105] S302, determining whether the exit photo is associated with the entrance photo.

[0106] Specifically, the captured vehicle exit photo is compared with all the entry photos in the entry image database. If the similarity between the vehicle exit photo and a certain entry photo in the entry database reaches a preset similarity value, for example, the similarity reaches more than 90%, it is determined that the entry photo is associated with the exit photo and step S303 is executed. Otherwise, it is determined that all the entry photos are not associated with the exit photo, and a prompt message related to the association failure is sent to the staff's mobile phone or computer or other smart devices, for example, "Vehicle photo association failed, please handle it in time" is sent to remind the staff to manually handle the exit vehicle that failed to associate in time.

[0107] S303, query and send payment information based on the appearance photo.

[0108] Specifically, based on the interrelated exit photos and entry photos, the corresponding payment information between the entry photo and the exit photo is queried, and the payment information and payment method are sent to the exit display screen and other display areas for display, so that the car owner can pay and exit.

[0109] S31, processing abnormal data.

[0110] like Figure 5 As shown, S31 includes the following two sub-steps:

[0111] S311, record abnormal data.

[0112] Specifically, the exit license plate information obtained twice, the exit identification data packet generated according to the preset equivalent correspondence relationship, and the secondary confirmation data packet are recorded and packaged to generate an abnormal identification data packet.

[0113] S312, sending the abnormal data packet to the smart device of the backend operation and maintenance personnel.

[0114] Specifically, the generated abnormal data identification package is adjusted to the abnormal database, and the abnormal data packets in the abnormal database are automatically and regularly sent to smart devices such as mobile phones or computers of back-end operation and maintenance personnel, so that the back-end operation and maintenance personnel can optimize and update the preset equivalent relationship based on the received abnormal data packets; for example, based on the analysis results of the abnormal data packets, the equivalent relationship is expanded from "1 and I" to "1, I and T".

[0115] S32, alarming for abnormal correlation situations.

[0116] like Figure 6 As shown, S32 includes the following two sub-steps:

[0117] S321, recording unrelated events.

[0118] Specifically, when all the entry identification data packets are not associated with the secondary confirmation data packets, this unrelated situation is accumulated and recorded in the form of a message event.

[0119] S322, determining whether the association situation is abnormal.

[0120] Specifically, determine whether the number of events accumulated and recorded within the preset period is greater than a preset reasonable value; if greater, send alarm information related to multiple occurrences of unrelated events to the smart device of the backend operation and maintenance personnel; for example, send "abnormality in the association of the exit license plate" to the backend operation and maintenance personnel's mobile phone or computer and other smart terminals, so that the backend operation and maintenance personnel can deal with the abnormal situation in time; otherwise, continue to accumulate and record the number of events.

[0121] The implementation principle of the embodiment of the present application is as follows: when a vehicle requests to enter or exit a parking lot, the vehicle's license plate information is similarly processed to form an entry identification data packet and an exit identification data packet, and then the relevance of the vehicle entering or exiting the parking lot is determined by comparing the entry identification data packet and the exit identification data packet; thereby reducing the possibility that the license plate information at the entrance and exit is difficult to match due to errors such as mud and sand obstruction between entry and exit; and improving the success rate of the parking lot in identifying and comparing the license plate information.
