[0049] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0050] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0052] The main solution of the embodiment of the present application is: perform image recognition on the vehicle image captured by the camera device to obtain the current position and target reservation information of the vehicle; determine the device position of the target device in the guide path of the target parking space according to the target reservation information; when the path distance between the current position and the device position is less than a preset distance, control the target device to perform a preset action.

[0053] Since parking lot gates, parking locks and other management devices will authenticate users through license plate recognition or ETC sensing, during the actual parking process, users who have reserved parking spaces in advance still need to wait in front of the relevant management devices to complete identity authentication and open the passage before they can continue to communicate. This will cause users to wait for a long time and low parking efficiency.

[0054] The present application collects vehicle images through camera equipment in the parking lot, performs image recognition on the vehicle images, obtains the current position and target reservation information of the user's vehicle, and determines the device position of the target device in the guidance path and the path distance between the device position and the current position according to the guidance path corresponding to the target reservation information. When the path distance between the current position and the device position is less than a preset distance, the target device is controlled to perform a preset action. When the user parks in the garage based on the reservation information, the target devices such as gates, parking locks, and charging piles can be controlled in advance to perform corresponding actions, thereby reducing the user's waiting time and improving the user's parking efficiency.

[0055] In order to better understand the above technical solution, exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0056] It should be noted that the execution subject of this embodiment can be a parking lot management system, or a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a control device of a parking lot management system, etc., and this embodiment does not specifically limit this. The parking lot management system is taken as an example to illustrate this embodiment and the following embodiments.

[0057] Based on this, the present application embodiment provides a control method for a parking lot management system, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the control method of the parking lot management system of the present application.

[0058] In this embodiment, the control method of the parking lot management system includes steps S10 to S30:

[0059] Step S10: performing image processing on the vehicle image captured by the camera device to obtain the current position and target reservation information of the vehicle;

[0060] In this embodiment, the parking lot is equipped with camera equipment at various key locations such as the parking lot entrance, corners, and sentry booths to collect real-time vehicle positioning images in the parking lot. The key locations can be determined based on the specific spatial structure of the parking lot. The camera equipment can be a monitoring device in the parking lot, or it can be an additionally deployed high-speed camera. The camera equipment can collect vehicle images after the ground circle sensing device senses the vehicle passing by, or it can recognize the collected images in real time, collect vehicle images after detecting an object in the shape of a vehicle, and transmit the collected images to the parking lot management system.

[0061] Furthermore, the parking lot management system is configured with an image processing model, which can identify the vehicle positioning image captured by the camera device. After receiving the vehicle positioning image captured and transmitted by the camera device, the parking lot management system will input the vehicle positioning image into the image processing model, and obtain the vehicle image and the positioning identification image in the vehicle positioning image, as well as the vehicle features of the vehicle image according to the image processing result. By matching the vehicle features with the reservation information, and according to the image distance between the positioning identification image and the vehicle image, the parking lot management system can determine the target reservation information and current position of the vehicle respectively.

[0062] It should be noted that the parking lot management system has preset positioning marks according to the actual scene of the parking lot to determine the current position of the vehicle. The preset marks can be fixed objects such as guardhouses and signboards in the parking lot. Since the shooting angle and shooting position of the camera equipment in the parking lot are fixed, each camera equipment will use the corresponding object as a positioning mark within the shooting range to ensure that the captured vehicle positioning image contains the positioning mark image. The actual distance and relative position of the positioning mark and the vehicle can be calculated based on the image distance and relative position of the positioning mark image and the vehicle image in the vehicle positioning image to determine the current position of the vehicle.

[0063] As an optional implementation of vehicle image recognition, Figure 2 As shown, Figure 2 This is a flow chart of the warehousing guidance involved in this application. The image processing model will perform edge detection, target detection and image segmentation on the vehicle positioning image to determine the vehicle image and positioning identification image in the vehicle positioning image. In the specific image processing process, the image processing model will first identify the edges of each part of the vehicle positioning image through edge detection, thereby dividing the image into different areas, and then through target detection, according to the edge contours of each divided area, match them with preset information, determine the objects corresponding to each segmented area, and determine the vehicle image and positioning identification image corresponding to the vehicle contour and positioning identification contour. The image processing model further performs image segmentation on the vehicle image, segments the feature areas of the vehicle image, identifies the feature information corresponding to each feature area, and determines the vehicle features based on the feature information.

[0064] Specifically, vehicle features may include vehicle color, license plate information, vehicle outline, window outline, and other information. Among them, through edge detection, the image processing model can determine the license plate area and window outline in the vehicle image. By removing the border of the license plate area and through vertical projection, the image processing model can segment the license plate area into a character image, and match the character image with the preset characters to determine the vehicle's license plate information.

[0065] Exemplarily, the image processing model may be composed of an image target detection algorithm and an image segmentation algorithm. Among them, the image target detection algorithm may be a YOLO (You Only Look Once) algorithm, which performs edge detection and target detection of the vehicle positioning image. By recognizing the image captured by the camera device through the target detection algorithm, the vehicle in the image can be determined more quickly and the vehicle image can be quickly extracted. And by further recognizing the feature information of the vehicle image through the image segmentation model, the accuracy of feature information extraction can be improved.

[0066] As another optional implementation of vehicle image recognition, the image recognition model can be a neural network model composed of a convolution layer and a maximum pooling layer. The convolution layer can extract features from the image, and the maximum pooling layer can compress features and remove unnecessary information from the image. The image recognition model can sample the image step by step based on the combination of the convolution layer and the maximum pooling layer to extract feature information of the image.

[0067] Step S20: determining a device position of a target device in a guide path of the target parking space according to the target reservation information;

[0068] In this embodiment, the target parking space is a parking space reserved by the user. After the user reserves the target parking space through the reservation platform, the parking lot management system generates and saves the target reservation information according to the target parking space, user information and user vehicle information.

[0069] Optionally, the parking lot management system can pre-store corresponding guidance paths based on different parking lot entrances and different target parking spaces, or generate corresponding guidance paths based on the real-time traffic conditions in the parking lot. In addition, since it is inconvenient for users to check their mobile phones while driving, or in underground parking lots, the information of the parking lot is poor, and users may not be able to receive guidance paths, the parking lot can also display the user's license plate number and guidance information at intervals through a preset prompt screen, combined with the display of the guidance path, to guide users to park, such as Guangdong Bxxxx, please go straight to the next intersection and turn right.

[0070] Furthermore, there may be devices such as gates and parking locks on the guidance path of the parking lot. The parking lot guidance system will use the devices in the guidance path as target devices and determine the device positions of these target devices in the guidance path.

[0071] Step S30: When the path distance between the current position and the device position is less than a preset distance, controlling the target device to execute a preset action.

[0072] In this embodiment, by controlling the target device to perform a preset action in advance, the user's waiting events can be reduced and parking efficiency can be improved. The preset action can be an action such as lifting a barrier, unlocking a parking lock, lowering an automatic door, etc. After obtaining the guide path of the target parking space based on the target reservation information, the parking lot control system can calculate the path distance between the current position and the position of each device on the guide path, and control the target device to perform the preset action when the path distance is less than the preset distance.

[0073] Optionally, under normal circumstances, since the driving speed of vehicles in the parking lot is low, the system can perform corresponding control actions based on the preset distance. However, in some cases, the system can also determine the driving speed of the vehicle and the real-time traffic conditions in the parking lot based on the captured images, and further determine the time when the vehicle arrives at the target device based on the driving speed and traffic conditions. Based on the time when the vehicle arrives at the target device, the parking lot management system can determine the time when the target device performs the preset action, and when the system time is the time to perform the preset action, control the target device to perform the preset action.

[0074] For example, when the camera at the entrance determines that the vehicle has entered the parking lot and is less than a preset distance from the barrier, it sends a lifting command to the barrier. After determining that the distance between the vehicle and the parking lock is less than a preset distance, an unlocking command will be sent to the parking lock. In addition, some devices in the parking lot will perform associated actions based on the actions of other devices. After the parking lock is unlocked, the charging pile on the target parking space will also be unlocked synchronously. After determining that the user has completed parking, the parking lot management system will also execute an elevator call action based on the current location.

[0075] The embodiment of the present application captures vehicle images through a camera in a parking lot, performs image recognition on the vehicle images, obtains the current position and target reservation information of the user's vehicle, and determines the device position of the target device in the guide path and the path distance between the device position and the current position according to the guide path corresponding to the target reservation information. When the path distance between the current position and the device position is less than a preset distance, the target device is controlled to perform a preset action. When the user parks in the garage based on the reservation information, target devices such as barriers, parking locks, and charging piles can be controlled in advance to perform corresponding actions, thereby reducing the user's waiting time and improving the user's parking efficiency.

[0076] Based on the same inventive concept, the present application also provides a second embodiment, referring to Figure 3 , Figure 3 This is a flow chart of a second embodiment of a control method for a parking lot management system of the present application.

[0077] In this embodiment, after determining the device position of the target device in the guide path of the target parking space according to the target reservation information as described in step S20, steps S21 to S23 are also included:

[0078] Step S21: determining the deviation of the vehicle path according to the current position;

[0079] Step S22: when the deviation is greater than a preset deviation threshold, determining that the vehicle path is deviated;

[0080] Step S23: displaying a prompt message of the path deviation on a display device according to the license plate information of the vehicle.

[0081] In this embodiment, the parking lot management system can also determine whether the vehicle has deviated from the path based on the current position of the vehicle, and promptly remind the user to return to the correct path. The parking lot management system can determine the deviation of the vehicle path based on the channel where the user is currently located and the vertical distance between the current position and the guide path. When the deviation is greater than the preset deviation threshold, the parking lot management system determines that the vehicle path is deviated, and displays a prompt message of the path deviation on the display device based on the vehicle's license plate information, and / or sends the prompt message to the user terminal. Among them, the user terminal can be the user's mobile terminal or vehicle-mounted terminal.

[0082] Furthermore, based on the current position of the vehicle and the guidance path, the parking lot management system can guide the vehicle to return to the route of the guidance path, or regenerate the guidance path to the target parking space.

[0083] In an embodiment of the present application, the parking lot management system can determine whether the user's parking path is deviated based on the current position of the vehicle, and promptly remind the user to return to the correct recording when it is deviated, thereby improving the user's parking efficiency.

[0084] Since the system introduced in the second embodiment of the present application is a system used to implement the method of the first embodiment of the present application, based on the method introduced in the first embodiment of the present application, the person skilled in the art can understand the specific structure and deformation of the system, so it is not repeated here. All systems used in the method of the first embodiment of the present application belong to the scope of protection of this application.

[0085] Based on the same inventive concept, the present application also provides a third embodiment, referring to Figure 4 , Figure 4 This is a flow chart of a third embodiment of a control method for a parking lot management system of the present application.

[0086] In this embodiment, the control of the parking lot management system includes steps S11 to S13:

[0087] Step S11: determining the parking status of the parking space according to the parking lock status of the parking space, and displaying the parking status on the reservation interface;

[0088] Step S12: after receiving the reservation information of the target parking space, obtaining the user information and vehicle information of the reservation information;

[0089] Step S13: updating the parking space status and parking space lock status of the target parking space.

[0090] In this embodiment, the parking lot management system is also associated with a reservation platform. Users can make reservations for available parking spaces on the reservation platform. After confirming the user's reservation, the parking lot will determine the target parking space and lock the target parking space through a parking space lock.

[0091] It should be noted that the parking space lock status includes locked and unlocked, and the parking space status includes parked, reserved, and free. The parking lot management system can determine whether the parking space status is free according to whether the parking space lock is locked, and display the corresponding parking space status on the reservation interface.

[0092] Specifically, after receiving the reservation information of the target parking space, the parking lot management system may obtain the user information and vehicle information of the reservation information, and update the parking space status and parking space lock status of the target parking space after completing the reservation.

[0093] The embodiment of the present application can determine the vacant parking spaces that can be reserved by the user according to the status of each parking space, and display the vacant parking spaces on the reservation interface to facilitate the user to make a reservation.

[0094] Since the system introduced in the third embodiment of the present application is a system used to implement the method of the first embodiment of the present application, based on the method introduced in the first embodiment of the present application, the person skilled in the art can understand the specific structure and deformation of the system, so it is not repeated here. All systems used in the method of the first embodiment of the present application belong to the scope of protection of the present application.

[0095] Based on the same inventive concept, the present application also provides a fourth embodiment, referring to Figure 5 , Figure 5 This is a flow chart of a fourth embodiment of a control method for a parking lot management system of the present application.

[0096] In this embodiment, the control of the parking lot management system includes steps S14 to S16:

[0097] Step S14: acquiring the video stream captured by the camera device in real time, and determining the image frames in the video stream;

[0098] Step S15: performing edge detection on the image frame to determine a boundary box in the image frame;

[0099] Step S16: Calculate the confidence of the bounding box, and when the confidence is greater than a preset threshold, use the image frame as the vehicle positioning image.

[0100] In this embodiment, in order to reduce the amount of data required for image processing and improve image processing efficiency, the parking lot management system may also use the image as a vehicle positioning image for image recognition when it is detected that the image captured by the camera device contains a vehicle.

[0101] Specifically, the parking lot control system obtains an image frame in a video stream captured by a camera device, performs edge detection on the image frame, and determines a bounding box in the image frame. The bounding box divides the image frame into different areas based on different objects, and determines the bounding box of each area. The parking lot management system can calculate the confidence of the bounding box according to a preset algorithm, and when the confidence is greater than a preset threshold, the image frame is used as a vehicle positioning image.

[0102] In an embodiment of the present application, the parking lot management system can first identify whether there is a vehicle image in the image captured by the camera device, and only when there is a vehicle image, use the captured image as a vehicle positioning image for image processing, thereby reducing the amount of data required for image processing, reducing resource occupation costs, and improving image processing efficiency.

[0103] Since the system introduced in the fourth embodiment of the present application is a system used to implement the method of the first embodiment of the present application, based on the method introduced in the first embodiment of the present application, the person skilled in the art can understand the specific structure and deformation of the system, so it is not repeated here. All systems used in the method of the first embodiment of the present application belong to the scope of protection of this application.
