Description

Technical Field

[0001] The present invention relates to the field of intelligent vehicle search, and in particular to a patrol identification system and a vehicle search method. Background Art

[0002] Currently, if a parking lot wants to provide users with reverse car search services, it needs to install parking space cameras and related cables in the parking lot, and identify and record the license plate numbers and photos of vehicles entering and leaving each parking space, so as to provide users with a car search service that allows them to check the location of the vehicle based on the license plate number.

[0003] Usually, customers who need to find their cars have their cars parked for too long, which leads to memory errors and the need to use the photos and locations retrieved from the parking system to confirm the parking location. The time customers spend looking for their cars is much later than the time the car enters the parking space and is identified. Even if the parking camera can quickly identify the license plate number for evidence after the vehicle enters the parking space, there is no urgent need for the rapid identification function in the process of finding the car. At the same time, although parking cameras can solve the problem of recording every vehicle entering and leaving the parking space, since parking cameras are one-to-one observation and evidence collection, their investment and construction costs are high, and parking cameras are only activated when there is a change in the vehicle in the parking space. They are idle most of the time, resulting in low utilization and efficiency of parking cameras.

[0004] At present, there is no technical solution that can solve the above-mentioned technical problems, and there is no inspection and recognition system and vehicle finding method. Summary of the invention

[0057] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] In order to solve the above technical problems, the present invention provides a patrol inspection and identification system. Figure 1 It is a structural diagram of the inspection and identification system provided by the present invention, comprising an inspection vehicle 1 and a remote server 2, wherein the inspection vehicle 1 is used to obtain parking space information from a target inspection area.

[0059] Optionally, the inspection vehicle 1 can be a manned vehicle or an unmanned vehicle, which will travel at a constant speed to the target inspection area along a preset path. The remote server 2 is communicatively connected to the inspection vehicle 1, and the inspection vehicle 1 can transmit the berth parking information obtained from the target inspection area to the remote server 2.

[0060] The inspection vehicle 1 includes an electronic tag reader 11, a vehicle identification camera 12, and a network transmission device 13. The electronic tag reader 11 is used to read an electronic tag on any berth side in the target inspection area. Each electronic tag corresponds to a berth number, such as Figure 1 As shown, it includes "berth number 99", "berth number 100" and "berth number 101", and in specific application scenarios, the berth numbers can be specifically set according to the actual numbering sequence, such as "berth number 001", "berth number A09", "berth number 99B", etc., which does not affect the specific implementation of the present invention and will not be elaborated here.

[0061] Optionally, the electronic tag reader 11 adopts a radio frequency identification (RFID) system and is installed and deployed in accordance with the general security technical requirements of the radio frequency identification system in "GB / T 35290-2017 Information Security Technology".

[0062] Optionally, the present invention can set a physical shielding cover for the electronic tag reader 11 and adjust the transmission power so that the radio frequency transmission and reflection radius between the electronic tag reader 11 and the electronic tag is limited to the width of the berth, thereby ensuring that only the electronic tags of the berths passed by the reader in the planned driving route are identified, and the electronic tags on the berths not in the planned driving route are not identified, thereby avoiding the occurrence of the situation where the license plate recognition result corresponds to other electronic tags. The present invention determines the set of electronic tags identified in sequence as the electronic tag flow information.

[0063] Optionally, the vehicle identification camera 12 is used to obtain original photos on any berth, and identify vehicle photos with license plate information from the original photos. The network transmission device 3 is used to transmit each tag identification time corresponding to all electronic tags and each berth number, all vehicle photos and the vehicle identification time corresponding to each vehicle photo to the remote server 2.

[0064] Optionally, the vehicle recognition camera 12 is used to photograph a vehicle on any berth, thereby obtaining an original photo of the berth. The present invention recognizes vehicle photos with license plate information from the original photos through a preset image recognition algorithm, thereby determining a set of sequentially recognized vehicle photos as vehicle photo stream information.

[0065] Optionally, the network transmission device 3 is used to transmit the electronic tag flow information and the vehicle photo flow information to the remote server 2, wherein the electronic tag flow information includes each tag identification time and each berth number corresponding to all electronic tags, and the vehicle photo flow information includes all vehicle photos and the vehicle identification time corresponding to each vehicle photo.

[0066] Optionally, the inspection vehicle 1 can take a one-way driving mode and periodically inspect the target inspection area, so as to obtain the parking records of different vehicles in the same berth, thereby realizing the update of the berth information. The present invention sets the inspection route and drives in one direction according to the route planning, which ensures the comprehensiveness of data collection. At the same time, the user can narrow the search range and save time when looking for a vehicle in an uninspected area. Furthermore, in order to ensure the integrity of data collection during inspection, the system sets related inspection items according to the preset berth point map. If omissions occur during the inspection process, the back-end server will discover them in time and display them as uninspected berths or uninspected areas.

[0067] The remote server 2 is used for:

[0068] For each tag identification time, determine all target differences between the tag identification time and all vehicle identification times, determine any vehicle identification time with a target difference less than a preset difference as the target identification time, determine the berth number corresponding to the tag identification time and the vehicle photo corresponding to the target identification time as the target berth parking information, and traverse all tag identification times until all berth parking information is determined.

[0069] Optionally, the present invention can pre-acquire the preset difference before the actual inspection operation according to the different sites of each inspection area, observe the time interval between the license plate recognition result generation time and the electronic tag reading time in the state of the parked vehicle in each berth in the target inspection area, and obtain a reference value, which is the preset difference. Using the preset difference, the present invention links the two flow streams with the time interval that meets the preset difference in the electronic tag flow information and vehicle photo flow information provided by the inspection vehicle, and merges them into the target berth parking information, which includes the license plate number, berth number, recognition time, and vehicle photo, and then traverses all tag recognition times until all berth parking information is determined.

[0070] Optionally, the remote server 2 is further used for:

[0071] For each parking space information, according to the parking space number corresponding to the parking space information, a correction difference is determined from a correspondence between a preset parking space number and a preset correction difference;

[0072] When the target difference corresponding to the parking space information is greater than the correction difference, generating an abnormal instruction, the abnormal instruction is used to indicate that the parking space number in the parking space information does not match the vehicle photo;

[0073] Sending the abnormal instruction to the mobile terminal to process the abnormal instruction;

[0074] The correspondence between the preset berth number and the preset correction difference is determined after averaging multiple historical differences obtained for each berth when multiple inspections are performed at a preset speed according to a preset driving route.

[0075] Optionally, after determining the parking information of all parking spaces, the present invention can further verify the accuracy of the parking information of all parking spaces. Specifically, due to the differences in the driving slope, driving speed, and distance between the inspection vehicle and the electronic tag and the parked vehicle during the inspection process, for each parking space, there may be a certain difference in the difference between the corresponding tag recognition time and the vehicle recognition time. The present invention can determine the corresponding relationship between the preset berth number and the preset correction difference after averaging the multiple historical differences obtained for each berth when performing multiple inspections according to the preset driving route and at a preset speed, and then determine the correction difference for different berths from the corresponding relationship between the preset berth number and the preset correction difference. , and then for different target differences, a comparison is performed in combination with different correction differences to check whether the verification requirements are met. Specifically, when the target difference corresponding to the parking space information is less than or equal to the correction difference, it is considered that the parking space number in the parking space information matches the vehicle photo, and the verification requirements are met. When the target difference corresponding to the parking space information is greater than the correction difference, an abnormal instruction is generated, indicating that the parking space number in the parking space information does not match the vehicle photo. At this time, the abnormal instruction needs to be sent to the mobile terminal to process the abnormal instruction, for example, the electronic tag flow information and the vehicle photo flow information are obtained again, or the accuracy of all parking space information is further verified again.

[0076] Optionally, the remote server 2 is further used for:

[0077] For each tag identification time, the berth number corresponding to the tag identification time having all target differences greater than or equal to the preset difference is determined as the berth number of the free berth;

[0078] For any original photo, if the license plate information cannot be identified from the original photo and it is determined that the vehicle has no license plate, the original photo is determined to be a photo without a license plate, and the parking space number of the vehicle without a license plate corresponding to the photo without a license plate is determined according to the vehicle identification time and all tag identification times of the photo without a license plate, and the parking space number of the vehicle without a license plate and the photo without a license plate are determined as parking information without a license plate;

[0079] The parking information of all parking spaces, the parking space numbers of vacant parking spaces and the parking information without license plates are stored in the remote server.

[0080] Optionally, if only the record of the electronic tag is read in the electronic tag flow information and the vehicle photo flow information, there is a separate electronic tag, and there is no license plate camera recognition result, then the berth number corresponding to the electronic tag is determined to be a berth without a vehicle. For each tag recognition time, the present invention determines the berth number corresponding to the tag recognition time with all target differences greater than or equal to the preset difference as a separate electronic tag, and the separate electronic tag corresponds to the berth number of the vacant berth.

[0081] During the specific implementation process, a millimeter-wave radar can also be installed on the side of the unmanned vehicle facing the direction of the parking space. If the electronic tag reader reads the parking space tag and the millimeter-wave radar does not feedback an obstacle, it can be considered that there is currently no car in the parking space and it is an empty parking space. When the customer is looking for a car, the route map corresponding to such parking spaces will be automatically excluded.

[0082] Optionally, the present invention takes into account the situation that there are vehicles without license plates, and centrally processes all vehicle photos in this situation, so that when performing relevant vehicle searches, users can quickly query the parking space number corresponding to the vehicle without license plates in all photos without license plates. Specifically, if the license plate information cannot be identified from the original photo, and it is determined that the vehicle has no license plate, it is considered that the license plate in the original photo cannot be identified not because it is not clear enough, but because the vehicle has no license plate. At this time, the original photo is determined to be a photo without license plates. According to the vehicle recognition time and all tag recognition times of the photo without license plates, the relevant target difference is determined, and these target differences are compared with the preset difference to determine the parking space number of the vehicle without license plates corresponding to the photo without license plates, and the parking space number of the vehicle without license plates and the photo without license plates are associated to determine the parking information of the vehicle without license plates; then, the present invention stores all parking space parking information, the parking space numbers of vacant parking spaces, and the parking information of the vehicle without license plates to the remote server for subsequent vehicle search needs.

[0083] Optionally, the remote server 2 is further used for:

[0084] For any original photo, if the license plate information cannot be identified from the original photo and the vehicle license plate is determined to be unclear, the original photo is determined to be the photo to be determined, and the parking space number of the license plate to be determined corresponding to the photo to be determined is determined according to the vehicle identification time and all tag identification times of the photo to be determined;

[0085] Generate a return inspection instruction, the return inspection instruction is used to instruct the inspection vehicle to take a photo of the vehicle in the parking space number of the to-be-determined license plate again, obtain a re-photographed photo, replace the to-be-determined photo with the re-photographed photo, and determine the parking space number of the to-be-determined license plate and the re-photographed photo as the parking information of the re-photographed license plate;

[0086] The re-photographed license plate parking information is stored in the remote server.

[0087] Optionally, when the license plate information cannot be identified from the original photo and it is determined that the vehicle license plate is not clear, it is considered that the license plate in the original photo cannot be identified not because the vehicle has no license plate, but because the license plate is not photographed clearly enough. During the inspection process, the vehicle may not be able to clearly identify the license plate due to obstacles, light, lens moisture, etc. At this time, the original photo is determined to be the photo to be determined, and the photo to be determined needs to be re-photographed. Specifically, the present invention determines the relevant target difference based on the vehicle recognition time and all label recognition times of the photo to be determined, and compares these target differences with the preset differences to determine the parking space number of the license plate to be determined corresponding to the photo to be determined.

[0088] Furthermore, after determining the parking space number of the to-be-determined license plate corresponding to the to-be-determined photo, a return inspection instruction is generated, instructing the inspection vehicle to photograph the vehicle on the parking space number of the to-be-determined license plate again to obtain a re-photographed photo, transmit the re-photographed photo to the remote server, replace the to-be-determined photo with the re-photographed photo, and perform license plate recognition on the re-photographed photo again to determine the vehicle license plate. After the present invention merges the parking space number of the to-be-determined license plate and the re-photographed photo into the re-photographed license plate parking information, the re-photographed license plate parking information is stored to the remote server.

[0089] Optionally, the remote server 2 is further used for:

[0090] Eliminate all vehicle photos, all photos without license plates and all re-shot photos from all original photos, and determine all vehicle photos to be added;

[0091] Generate a supplementary recording instruction based on all the vehicle photos to be supplemented, wherein the supplementary recording instruction is used to instruct to read the electronic tag of the berth number corresponding to each supplementary vehicle photo again to obtain the berth number after supplementation;

[0092] All the parking information after supplementary recording is determined according to all the vehicle photos to be supplemented and the supplementary parking space number corresponding to each vehicle photo to be supplemented, and all the parking information after supplementary recording is stored in the remote server.

[0093] Optionally, the present invention provides a solution for identifying the situation where there are vehicle photos in the flow but no electronic tags. Specifically, it is first necessary to determine all vehicle photos that exist but do not correspond to electronic tags to be supplemented. Those skilled in the art understand that among all the original photos, all photos except all vehicle photos, all photos without license plates and all re-shot photos are vehicle photos to be supplemented that need to have electronic tags supplemented.

[0094] Optionally, after determining all the vehicle photos to be supplemented, the present invention can adopt manual confirmation or automatic system supplementation for each vehicle photo to be supplemented to realize the supplementary reading of the electronic tag. Specifically, the present invention generates a supplementary instruction based on all the vehicle photos to be supplemented, instructing to read the electronic tag again for the berth number corresponding to each supplemented vehicle photo to obtain the berth number after supplementation, and then traverses all the vehicle photos to be supplemented to determine the berth number after supplementation corresponding to each vehicle photo to be supplemented, determines all the parking information after supplementation based on all the vehicle photos to be supplemented and the berth number after supplementation corresponding to each vehicle photo to be supplemented, and stores all the parking information after supplementation to the remote server.

[0095] Optionally, the present invention changes the license plate recognition camera in traditional vehicle identification into a mobile patrol vehicle, and conducts mobile patrol and evidence collection on parking lots or road parking sections within a preset period. At the same time, utilizing the characteristic that the parking space location is a fixed attribute, an electronic tag is installed on the parking space, and an electronic tag reader is added to the patrol vehicle. The time when the mobile device reads the electronic tag is associated with the time when the vehicle identification camera takes the photo, and the associated information between the parking space and the vehicle can be obtained. At the same time, some fixed car search points are set in parking lots or road parking sections, and the walking route between each parking space and the car search point is determined by a route map to form a picture library for easy retrieval and viewing on a mobile phone. The above technical solution can meet all the user's needs for car search services. The present invention will greatly enhance the utilization rate of a single device and greatly reduce the construction investment of the operator.

[0096] The present invention provides a patrol identification system and a vehicle finding method. The patrol vehicle is used to patrol in a target patrol area to continuously obtain electronic tag flow information and vehicle photo flow information, and the flow information is compared by a preset difference, and the tag identification time and vehicle identification time with similar acquisition time are associated, so as to associate the parking space number and the license plate number. The present invention combines an image recognition method and an identification method for reading electronic tags to jointly identify the license plate number on the parking space, and draws an electronic map according to the parking space location where the electronic tag is located, providing data support for subsequent users to find the vehicle, so that users who are looking for the vehicle can quickly know the location of the vehicle, avoiding the need for traditional technology to install a fixed license plate recognition camera on the parking space to achieve reverse vehicle finding service, reducing related investment costs, and can supplement evidence collection for imported vehicles that are not identified, improve parking lot business data, and enhance customer experience. It is suitable for large-scale application and promotion in the field of parking operation management.

[0097] Figure 2 This is one of the flow charts of the inspection and identification system provided by the present invention. The vehicle search method includes:

[0098] Step 101, receiving a first vehicle search instruction from any vehicle search point, wherein the first vehicle search instruction at least includes target license plate information;

[0099] Step 102: In response to the first vehicle search instruction, a target parking space number is determined from a remote server according to the target license plate information;

[0100] Step 103: determining a target route map from a preset route database according to the target berth number and the vehicle search point;

[0101] Step 104: Display the target route map in a preset display terminal.

[0102] In step 101, the preset display terminal is a car search display screen corresponding to the car search point, or a mobile terminal; when the preset display terminal is a car search display screen corresponding to the car search point, before receiving the first car search instruction from any car search point, the target license plate information is input into the car search display screen, so as to query the parking space where the target vehicle is located through the target license plate; when the preset display terminal is a mobile terminal, before receiving the first car search instruction from any car search point, the mobile terminal scans the corresponding QR code information on the car search point, and according to the QR code information, a web page jump is realized or a preset car search interface is called in the mobile terminal, and the target license plate information is input into the preset car search interface, so as to query the parking space where the target vehicle is located through the target license plate; further, the remote server receives the first car search instruction from any car search point, and the first car search instruction at least includes the target license plate information.

[0103] In step 102, in response to the first vehicle search instruction, the target parking space number is determined from the remote server according to the target license plate information. Because before executing the vehicle search step, all parking space parking information, parking space numbers of vacant parking spaces and parking information without license plates are pre-stored in the remote server, the re-photographed license plate parking information is also stored in the remote server, and all supplemented parking information is also stored in the remote server, so that when the target license plate information is used to query the parking space, the target parking space number can be determined from the remote server.

[0104] In step 103, the present invention pre-constructs a preset route database, which can determine multiple optional routes according to the target parking space number and the vehicle search point, determine the route with the best path and the shortest distance as the target route, and display the target route on a preset map to construct a target route map. It can also construct a correspondence between all parking space numbers and vehicle search points and all route maps in the preset route database, so that when the target parking space number and the vehicle search point are determined, the target route map can be directly determined.

[0105] In step 104, the target route map is displayed on a preset display terminal, which may be a mobile phone screen, a tablet screen, a display screen provided on a roadside vehicle search device, etc., to provide vehicle search guidance to the user.

[0106] Optionally, the present invention can also set a car search sign at the car search point in the parking lot or road berth, and display the page link of the car search system in a way that can be accessed by mobile phone. The mobile phone access method can be a method of scanning a QR code to open a web page or calling a small program to query, or guiding the user to click on the relevant menu through the official account, wherein a parameter is added to the link of each query page, and the corresponding information of the parameter is the current car search point number. When the user accesses the system backend through the link, the back-end server obtains the target car search point according to the preset parameters.

[0107] Furthermore, users can also open the car search website or mini program through their mobile phones and enter the license plate number they need to find. The car search service system of the back-end server retrieves the identification record of the license plate number in the records of the inspection data analysis system. If the license plate number exists, the berth information corresponding to the electronic tag in the inspection record is retrieved, and the car search point where the user is located is obtained according to the parameter characteristics of the car search point website. Then, the target route map between the berth number and the car search point is searched in the preset route database and sent to the user's mobile phone. On the target route map, the user can continue to scan the QR code of other car search points on the route to retrieve the new target route map and realize real-time car search navigation.

[0108] Figure 3 This is a second flow chart of the inspection and identification system provided by the present invention. Before determining the target route map from the preset route database according to the target berth number and the vehicle search point, the method further includes:

[0109] Step 301, determining the point coordinates of each vehicle search point and the berth coordinates of each berth number;

[0110] Step 302: for each car search point, determine a route map from the point coordinates corresponding to the car search point to the berth coordinates corresponding to any berth number;

[0111] Step 303, traverse all the car search points, determine all the route maps from all the car search points to any berth number, and store all the route maps from different car search points to different berth numbers in the preset route database.

[0112] In step 301, before determining the target route map, the present invention can pre-construct a preset route database, specifically, draw a plan view of the building or road parking section, compile coordinates of the parking spaces by number, construct a preset three-dimensional coordinate system, set multiple car search points in the building or road parking section, compile coordinates of the car search points on the plan view of the building or road parking section, and then determine the point coordinates of each car search point and the berth coordinates of each berth number according to the preset three-dimensional coordinate system.

[0113] Optionally, an electronic tag is placed outside each berth, and the correspondence between the electronic tag and the berth number coordinates is recorded, thereby realizing the association between the electronic tag and the berth information.

[0114] In step 302, for each car search point, a route map from the point coordinates corresponding to the car search point to the berth coordinates corresponding to any berth number is determined and drawn into a fixed screen, and in step 303, all car search points are traversed, each fixed screen is numbered, all route maps from all car search points to any berth number are determined, and all route maps from different car search points to different berth numbers are stored in the preset route database, which is a picture database. In this way, the present invention does not rely on the installation of other positioning and navigation devices in the parking lot to interact with the mobile phone. By continuously scanning different car search points, the mobile phone page can continuously update the departure information of the car search point, thereby retrieving different target route maps in the picture database, and the user can navigate to the target parking space on foot.

[0115] Figure 4 This is the third flow chart of the inspection and identification system provided by the present invention. Before or after receiving the first vehicle search instruction from any vehicle search point, the method further includes:

[0116] Step 401, receiving a second vehicle search instruction from any vehicle search point, wherein the second vehicle search instruction includes searching for a photo without a license plate;

[0117] Step 402: In response to the second vehicle search instruction, display all parking information without license plates on the preset display terminal;

[0118] Step 403: receiving a third vehicle search instruction from the vehicle search point, wherein the third vehicle search instruction is used to determine target vehicle-no-license plate parking information from all vehicle-no-license plate parking information;

[0119] Step 404: In response to the third vehicle search instruction, determine a target parking space number according to the target parking space without a license plate information, so as to determine the target route map according to the target parking space number.

[0120] In step 401, when the vehicle queried by the user is a vehicle without a license plate, the vehicle search method of the present invention can also provide it with a reliable vehicle search service. Specifically, the user clicks a vehicle search button without a license plate on the vehicle search point or the smart terminal to generate a second vehicle search instruction, receives the second vehicle search instruction from the vehicle search point, and searches for photos of vehicles without license plates.

[0121] In step 402, the second vehicle search instruction is responded to, a query is performed using a remote server to obtain a query result in the current state, and all corresponding parking information without license plates in the current query state is displayed in the preset display terminal.

[0122] In step 403, all the parking information without license plates is displayed in the preset display terminal. The user determines the target vehicle corresponding to the target parking information without license plates during the browsing process, and clicks on the vehicle photo corresponding to the target vehicle to generate the third vehicle search instruction. The remote server receives the third vehicle search instruction from the vehicle search point.

[0123] In step 404, the parking information without a license plate includes the parking space number of the vehicle without a license plate and the photo of the vehicle without a license plate. The remote server responds to the third vehicle search instruction, determines the target parking space number according to the target parking space number, and determines the target route map from the preset route database according to the target parking space number.

[0124] Figure 5 This is a fourth flow chart of the inspection and identification system provided by the present invention. After responding to the first vehicle search instruction, the method further includes:

[0125] Step 501: when it is determined that the parking space number corresponding to the target license plate information cannot be found, determining the inspection status of the inspection vehicle;

[0126] Step 502: when it is determined that the inspection vehicle is currently inspecting, determine an uninspected area based on the target inspection area and the inspected area;

[0127] Step 503: Display the uninspected area in the preset display terminal.

[0128] In step 501, the present invention also provides a solution for providing a user with vehicle search suggestions and a vehicle search range for the situation where the target parking space number or the target route map cannot be determined after searching for the vehicle using the vehicle search method provided by the present invention. Specifically, since the inspection of the patrol vehicle takes time, if the user searches for the vehicle during the inspection of the patrol vehicle, it may result in the vehicle that the user is looking for being in an area that has not been inspected. At this time, the present invention first needs to determine the inspection status of the current patrol vehicle after the user has failed to find the vehicle.

[0129] In step 502, when it is determined that the inspection vehicle is currently inspecting, the inspected area is determined based on the starting position, current position and inspected route of the inspection vehicle, and the remaining area in the target inspection area except the inspected area is determined as the uninspected area, and the uninspected area is then displayed to the user to instruct the user to continue searching for the target vehicle in the uninspected area, or to continue waiting for the inspection vehicle to inspect and then query again after a preset time. The present invention can not only significantly reduce the user's vehicle search range, but also save the user's vehicle search time and improve the user's vehicle search experience.

[0130] Optionally, if the inspection vehicle has completed all inspection work in the target inspection area, but the user still cannot query the target license plate, the back-end server can display photos of parking spaces adjacent to all unrecognizable vehicle identification records during the inspection. If the user sees the target vehicle in the photo, he or she can click on the nearby parking space for confirmation. After the user confirms the nearby parking space of the target vehicle based on the picture, the system determines the nearby parking space number as the target parking space number based on the parameter characteristics of the car search point website, and determines the target route map from the preset route database based on the target parking space number and sends it to the user's mobile phone.
