Description

Technical Field

[0001] The present invention belongs to the technical field of parking space planning, and in particular relates to a method, device, equipment and medium for planning the number of parking spaces based on vehicle size data. Background Art

[0002] As the number and types of cars increase, the size of vehicles also shows a diversified development. In order to meet the demand for parking, it is generally necessary to set up parking lots in areas where vehicles are concentrated.

[0003] When planning parking spaces, parking space dimensions are often fixed and cannot effectively accommodate vehicles of varying sizes, especially large SUVs and MPVs. This can make these vehicles difficult to park or occupy excessive space after parking, reducing parking space utilization. Furthermore, parking space layouts are often made without considering the actual size of the vehicle, and the lack of size-based parking space markings makes it difficult for drivers to quickly find a space suitable for their vehicle, increasing parking time and difficulty. Summary of the Invention

[0004] The present invention provides a method for planning the number of parking spaces based on vehicle size data, which can optimize the layout and identification of parking spaces and improve the utilization rate of parking spaces in a parking lot.

[0005] Methods include:

[0006] S101, defining a parking space division strategy library having multiple parking space division strategies, where each parking space division strategy corresponds to a parking space length and width information;

[0007] S102: Calling a parking space division strategy from a parking space division strategy library and setting it as the current parking space division strategy;

[0008] S103, scanning the vehicle shape and obtaining the length, width, and coordinates of the vertices corresponding to the four corners;

[0009] S104: Calculate the size information of the vehicle shape based on the length and width obtained by scanning and the coordinates of the vertices corresponding to the four corners, and compare it with the length and width information of the parking space corresponding to the current parking space division strategy;

[0010] S105 : When the size information matches the parking space length and width information corresponding to the current parking space division strategy, the parking space length and width information corresponding to the vehicle shape is planned according to the current parking space division strategy.

[0011] It should be further explained that the method further includes:

[0012] Preset parking space threshold range;

[0013] When the size information of the vehicle shape is smaller than the length and width information of the parking space corresponding to the current parking space division strategy, determine whether the size information is smaller than the actual margin value of the length and width information of the parking space according to the current parking space division strategy;

[0014] When the actual margin value is not greater than the parking space threshold range, the vehicle shape is planned according to the current parking space division strategy;

[0015] When the actual margin value is greater than the parking space threshold range, a prompt is triggered to ask whether to continue planning.

[0016] It should be further explained that the method further includes: scanning the shape of the vehicle and obtaining its length, width and the coordinates of the vertices corresponding to the four corners of its four sides.

[0017] It should be further explained that the first scanning starting point coordinates are preset, and the vehicle shape is scanned for the first time based on the first scanning starting point coordinates to obtain the length and width of the vehicle shape and the coordinates of the vertices corresponding to the four corners of a length side and a width side;

[0018] Perform a second scan on the vehicle shape to obtain the coordinates of the four corners corresponding to the other length side and the other width side;

[0019] The actual width value is calculated based on the coordinates of the four corners of the two length sides obtained by two scans and the length and width of the vehicle; and the actual length value is calculated based on the coordinates of the four corners of the two width sides obtained by two scans and the length and width of the vehicle.

[0020] It should be further explained that, in the method, the second scanning starting point coordinates of the second scanning are obtained based on the coordinates of the vertices corresponding to the four corners of the length side and the width side obtained by the first scanning; and the vehicle shape is scanned a second time based on the second scanning starting point coordinates;

[0021] The scanning starting point of the second scan is obtained by translating the coordinates of the four corners corresponding to the vertices obtained in the first scan. The coordinates of the four corners corresponding to the vertices of the other length side obtained in the second scan are in the same X-axis direction or the same Y-axis direction as the coordinates of the four corners corresponding to the vertices of the previous length side obtained in the previous scan.

[0022] It should be further explained that, in the method, a geometric calculation method is used to calculate the actual length and width of the vehicle.

[0023] It should be further explained that, assuming that the length of a vehicle is carLength, the width is carWidth, the width of the parking lot is width, and the length is length, and the length of the two-way aisle is at least twice the width of the vehicle, that is, 2carWidth, then the number of parking spaces in the current area is calculated as:

[0024] The number of rows y + (y - 1)2carWidth < length, and the number of each row x*carWidth < width.

[0029] An information comparison module, which is used to calculate the size information of the vehicle shape according to the length, width and the corresponding vertex coordinates of the four corners obtained by scanning, and compare it with the parking space length and width information corresponding to the current parking space division policy;

[0030] A planning matching module, which is used to plan the parking space length and width information corresponding to the vehicle shape according to the current parking space division policy when the vehicle shape size information matches the parking space length and width information corresponding to the current parking space division policy.

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0047] See also Figure 1 FIG. 1 is a flow chart of a method for planning the number of parking spaces based on vehicle size data in a specific embodiment. The method includes:

[0048] S1. Define a parking space division strategy library having multiple parking space division strategies, where each parking space division strategy corresponds to the length and width information of a parking space.

[0049] In some embodiments, standard size data of types such as small cars, large cars, and SUVs, as well as parking space length and width information under different parking space division strategies are collected.

[0050] Optionally, this embodiment can first construct a parking space division strategy library. Based on the collected data, a parking space division strategy library is constructed that includes multiple parking space division strategies. Each strategy corresponds to specific parking space length and width information. The data in the parking space division strategy library is integrated into a queryable and callable terminal for subsequent invocation.

[0051] As can be seen, this embodiment builds a parking space allocation strategy library, making parking space planning more flexible. Appropriate parking space allocation strategies can be selected based on different needs and scenarios. This ensures consistent and standardized parking space allocation and improves parking lot utilization. Furthermore, the strategy library can be easily updated and expanded as vehicle types and parking needs change.

[0052] As an implementation of this embodiment, the parking spaces can be arranged into vertical, parallel and oblique types according to actual needs.

[0053] Vertical parking spaces are perpendicular to the direction of travel. Parallel parking spaces are parallel to the direction of travel, making it easier for vehicles to enter and exit. Diagonal parking spaces are at a certain angle to the direction of travel, allowing more vehicles to be parked within a limited space.

[0054] S2. Call the parking space division strategy in the parking space division strategy library and set it as the current parking space division strategy.

[0055] In some embodiments, the desired parking space allocation strategy can be selected or input through a user interface configured on the device, or the device can automatically retrieve the strategy from a strategy library and set it as the current strategy. This improves the efficiency of parking space planning and reduces the complexity of manual strategy selection. It ensures that the selected strategy matches the current parking needs and vehicle types, providing clear guidance and basis for subsequent parking space planning.

[0056] S3. Scan the vehicle shape and obtain the length, width and coordinates of the vertices corresponding to the four corners.

[0057] In some embodiments, a laser scanner can be used to perform a three-dimensional scan of the vehicle to obtain point cloud data of the vehicle surface. The scanned point cloud data is processed and analyzed to extract the length, width, and coordinates of the vertices corresponding to the four corners of the vehicle.

[0058] Optionally, a coordinate measuring machine (CMM) can be used to precisely measure the vehicle. This can provide precise dimensional information about the vehicle's shape, providing an accurate basis for parking space planning. This not only captures the length and width, but also the coordinates of the four corners, facilitating subsequent parking space planning and adjustments.

[0059] S4. Calculate the size information of the vehicle shape based on the length and width obtained by scanning and the coordinates of the vertices corresponding to the four corners, and compare it with the length and width information of the parking space corresponding to the current parking space division strategy.

[0060] In some embodiments, the scanned vehicle dimension information is calculated and analyzed to obtain the vehicle's length, width, and other information. The calculated vehicle dimension information is compared with the length and width information of the parking space corresponding to the current parking space division strategy to determine whether the vehicle is suitable for the parking space under the strategy.

[0061] It can be seen that this embodiment ensures that the selected parking space division strategy can meet the current vehicle parking needs. If the current strategy does not meet the needs, the strategy can be adjusted based on the comparison results to meet the parking space planning requirements.

[0062] S5. When the size information matches the parking space length and width information corresponding to the current parking space division strategy, the parking space length and width information corresponding to the vehicle shape is planned according to the current parking space division strategy.

[0063] In some embodiments, parking spaces are planned and laid out in the parking lot based on the current parking space allocation strategy and vehicle size information. Parking space markings, numbers, and other markers are drawn to ensure the accuracy and legibility of parking space planning. This improves parking lot space utilization through reasonable parking space planning, ensuring that vehicles can be parked in the planned spaces in an orderly manner. Optimizing parking space layout and markings improves parking space utilization.

[0064] In some specific embodiments, a parking space division strategy library with multiple parking space division strategies is defined, and each parking space division strategy is suitable for planning parking spaces with its corresponding length and width information, wherein the parking space length and width information corresponding to the parking space division strategies in the parking space division strategy library is the parking space length and width information calculated based on the size of the parking space map to be planned in the current system and the set parking space length and width information.

[0065] The parking space division strategy of this embodiment can be used to plan a specific planning method with parking space length and width information. After the parking space to be planned is placed in the planning area, the vehicle shape is first scanned, and the vertex of the vehicle is parsed and the coordinates of the vertex are recorded. The purpose of the scanning operation is to confirm the length, width and vertex of the vehicle in order to obtain the planning target point.

[0066] In order to obtain the vertex coordinates of the vehicle, the vehicle shape is compared with the current parking space division strategy. The dimensional information of the vehicle shape is calculated by scanning the vertex coordinates obtained. Then, the dimensional information of the vehicle shape is compared with the length and width information of the parking space corresponding to the current parking space division strategy. When the dimensional information of the vehicle shape matches the length and width information of the parking space corresponding to the current parking space division strategy, it means that the vehicle shape is suitable for the current parking space division strategy, and the vehicle shape can be planned according to the current parking space division strategy.

[0067] In this embodiment, the area ratio of the parking lot can also be allocated according to the ratio of each vehicle size.

[0068] Specifically, let the length of the vehicle be carLength, the width be carWidth, the width of the parking lot be width, the length be length, and the length of the two-way aisle be at least twice the width of the vehicle, i.e., 2carWidth. Then the calculation method for the number of parked vehicles in the current area is as follows:

[0069] The number of rows y + (y - 1)2carWidth < length, and the number of vehicles in each row x * carWidth < width.

[0070] Based on the data of the length, width of each area and the vehicle size, the maximum number of parked vehicles in each area is obtained, and vehicles of different sizes are allocated to different areas in descending order.

[0071] As an example, the parking lot reserves dynamically adjustable parking spaces for use when the number of parking spaces does not meet the current parking demand. Upon receiving a request instruction to park, obtaining the available parking information in the parking area, determining whether there are parking spaces available for the vehicle in the parking area, sending a marking instruction to the controllable marking device installed in the parking area, and updating the parking area information according to the recorded request instruction. This method can dynamically adjust the parking spaces according to the existing parking situation, improving the flexibility and utilization efficiency of the parking lot. When a car enters the electronic fence area of the parking lot, the electronic display screen will prompt the vehicle to park in the specified area according to the size of the current vehicle.

[0072] Based on the above embodiments, in order to further improve the reliability of the method for planning the number of parking spaces based on vehicle size data provided in the above embodiments, the following is a feasible method. In one embodiment, the planning method further includes the following steps:

[0073] When the size information of the vehicle shape is greater than the length and width information of the parking space corresponding to the current parking space division strategy, a prompt message is sent.

[0074] Specifically, when the size information of the vehicle shape is greater than the length and width information of the parking space corresponding to the current parking space division strategy, it means that the vehicle shape is not suitable for the current parking space division strategy, and the planning is stopped.

[0075] The device will automatically stop the planning and remind the planner, which can effectively screen the parking spaces to be planned under the current parking space division strategy, effectively avoiding the parking spaces that are not suitable for the current parking space division strategy, ensuring that the parking spaces to be planned are all planned according to the most suitable parking space division strategy, and ensuring the reasonable and effective parking space planning.

[0076] In this embodiment, when the size information is equal to the length and width information of the parking space corresponding to the current parking space division strategy, the vehicle shape is planned according to the current parking space division strategy.

[0077] Furthermore, as a refinement and expansion of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, as shown below: Figure 2 As shown, the method for planning the number of parking spaces based on vehicle size data further includes the following steps:

[0078] S301. Preset a parking space threshold range.

[0079] S302: When the size information of the vehicle shape is smaller than the length and width information of the parking space corresponding to the current parking space division strategy, determine whether the size information is smaller than the actual margin value of the length and width information of the parking space corresponding to the current parking space division strategy.

[0080] S303: When the actual margin value is not greater than the parking space threshold range, plan the vehicle shape according to the current parking space division strategy.

[0081] S304: When the actual margin value is greater than the parking space threshold range, a prompt is triggered to determine whether to continue planning.

[0082] In some embodiments, each parking space division strategy corresponds to a corresponding parking space length and width information. When any parking space division strategy is called and set as the current parking space division strategy, the corresponding parking space length and width information is a fixed value.

[0083] The current parking space division strategy may allow a certain parking space threshold range in the planned parking space size, and parking spaces within the threshold range are all applicable to the current parking space division strategy.

[0084] When the size information is smaller than the length and width information of the parking space corresponding to the current parking space division strategy, and the actual margin value is not greater than the parking space threshold range, it means that the size information of the vehicle shape meets the parking space planning requirements under the current parking space division strategy.

[0085] In some embodiments, the vehicle shape is applicable to the current parking space division strategy, and the vehicle shape is planned according to the current parking space division strategy; when the actual margin value of the vehicle shape is greater than the parking space threshold range, it means that the size information of the vehicle shape is too large, and a prompt will be triggered as to whether to continue planning.

[0086] When the planner sees this prompt, he or she can choose to continue planning or stop planning. When the planner chooses to continue planning, the device plans the vehicle shape based on the current parking space division strategy. When the planner chooses to stop planning, the system stops planning.

[0087] In this embodiment, the parking space and vehicle shapes corresponding to the parking space division strategy are both rectangular. The length and width information of the parking space and the dimensions of the vehicle shape specifically refer to the corresponding length values ​​and width values. The comparison of the sizes actually specifically refers to the comparison of the numerical sizes of the length values ​​and width values.

[0088] According to an embodiment of the present application, the planning method further includes scanning the vehicle shape and obtaining its length, width, and the coordinates of the vertices corresponding to the four corners of its four sides. The scanning of the vehicle shape specifically includes the following steps: Figure 3 As shown,

[0089] S401: Preset the first scanning starting point coordinates, perform a first scan on the vehicle shape according to the first scanning starting point coordinates, and obtain the length, width, and four corner vertex coordinates corresponding to a length side and a width side of the vehicle shape.

[0090] In some embodiments, a 3D camera is used to capture point cloud data in three-dimensional space. A suitable starting point position is selected around the vehicle, and the coordinates of the position are preset in the scanning device as the first scanning starting point coordinates.

[0091] The scanning device starts scanning the vehicle from a preset starting point. During the scanning process, the device records point cloud data of the vehicle's surface. The resulting point cloud data is processed. Using techniques such as image recognition and edge detection, the length and width of the vehicle's shape, as well as the coordinates of the vertices corresponding to the four corners of a length edge and a width edge, are extracted.

[0092] As can be seen, high-precision scanning equipment can accurately capture the length and width of the vehicle, as well as the coordinates of key vertices, providing accurate data support for subsequent parking space planning. Presetting the scanning starting point and automating the scanning process can improve the efficiency of parking space planning.

[0093] S402: Scan the vehicle shape for the second time to obtain the coordinates of the four corners corresponding to the other length side and the other width side.

[0094] In some embodiments, the starting point of the second scan is determined by selecting a suitable starting point as the starting point of the second scan based on the coordinates of the four corners of the length side and the width side obtained by the first scan.

[0095] The starting point of this embodiment may be a point after translation along the X-axis or the Y-axis, so as to quickly obtain the vertex coordinates of the other length side and the width side.

[0096] This embodiment can scan the vehicle starting from the starting point of the second scan. The scanning process is similar to the first scan, where the vertex coordinates of the other length side and width side are used.

[0097] Similarly, the scanned point cloud data is imported into the software for processing to extract the required vertex coordinate information.

[0098] As can be seen, through two scans, the vertex coordinates of all key edges of the vehicle can be fully obtained, providing more comprehensive data support for parking space planning. By properly selecting the starting point of the second scan, the scanning range and time can be reduced, and the scanning efficiency can be improved.

[0099] S403: Calculate the actual width value based on the coordinates of the four corners of the two length sides obtained by two scans and the length and width of the vehicle; and calculate the actual length value based on the coordinates of the four corners of the two width sides obtained by two scans and the length and width of the vehicle.

[0100] In some embodiments, the vertex coordinate data obtained from the two scans are sorted to extract the vertex coordinates of the two length sides and the two width sides respectively.

[0101] This embodiment uses the distance formula between two points and calculates the actual length and width of the vehicle based on the vertex coordinates. Combined with the length and width information of the vehicle, comparison and adjustment are performed.

[0102] This embodiment can calculate the actual length and width of the vehicle, providing accurate data basis for parking space planning. Based on the actual size of the vehicle and the length and width information of the parking space, the parking space layout and size can be planned more reasonably, improving space utilization and parking efficiency.

[0103] In some specific embodiments, the method for planning the number of parking spaces based on vehicle size data involved in this application further includes the following steps:

[0104] S501: Obtain the second scanning starting point coordinates of the second scanning according to the coordinates of the four corners corresponding to the vertices of the length side and the width side obtained by the first scanning.

[0105] Here, we analyze the vertex coordinates obtained from the first scan to determine the approximate position and orientation of the vehicle shape on the 2D plane. Based on the vehicle's shape and scanning requirements, we select an appropriate translation direction and distance to calculate the starting coordinates for the second scan. This starting coordinate can be a point after a translation along the X or Y axis.

[0106] S502: Scan the vehicle shape for the second time according to the second scanning starting point coordinates.

[0107] In this embodiment, the scanning device sets parameters such as the starting point coordinates, scanning range, and scanning accuracy for the second scan. The scanning device is then activated and scans the vehicle a second time, starting from the preset starting point. During the scan, the device records point cloud data of the vehicle's surface.

[0108] This second scan can further supplement and improve the vehicle shape data, providing data support for parking space planning. Based on vehicle shape data, parking space layout and size can be accurately planned, improving the overall efficiency of the parking lot.

[0109] In some specific embodiments, the first scanning starting point coordinate is the starting point coordinate when the scanning action starts. The first scan is performed based on the starting point coordinate to obtain the length and width of the vehicle shape and the vertex coordinates corresponding to the four corners of one length side and one width side of the vehicle shape.

[0110] Furthermore, the vehicle shape is scanned a second time, and the scanning starting point coordinates of the second scan are obtained by translating the vertices of one of the length sides and one width side obtained in the first scan along the X-axis or along the Y-axis, so as to obtain the coordinates of the four corresponding vertices on the other length side and width side at a faster speed.

[0111] In this embodiment, the scanning starting point of the second scan is obtained by translating the coordinates of the four corners corresponding to the vertices obtained in the first scan, and the coordinates of the four corners corresponding to the vertices of the other length side obtained in the second scan are in the same X-axis direction or the same Y-axis direction as the coordinates of the four corners corresponding to the vertices of the previous length side obtained in the previous scan.

[0112] It should be noted that the X coordinate values ​​or Y coordinate values ​​of the corresponding vertices of the two four corners on the two length edges are the same.

[0113] In this embodiment, the coordinates of the vertices corresponding to the four corners of the other width side are in the same X-axis direction or the same Y-axis direction as the coordinates of the vertices corresponding to the four corners of the previous width side obtained in the previous scan, and the X-coordinate values ​​or Y-coordinate values ​​of the two vertices corresponding to the four corners on the two width sides are the same.

[0114] After obtaining the vertex coordinates corresponding to the four corners of the four sides of the vehicle shape, the distance between the two vertices can be calculated based on the vertex coordinates corresponding to the four corners of the two parallel length sides. Combined with the length and width of the vehicle shape, the actual width value of the vehicle shape can be calculated.

[0115] In this embodiment, the actual length value of the vehicle shape can be calculated based on the coordinates of the four corresponding vertices of the two parallel width sides and the length and width.

[0116] It can be seen that by properly selecting the starting coordinates for the second scan, the scanning process can be simplified and unnecessary scanning range and time can be reduced. Ensuring that the starting point of the second scan is coordinated with the results of the first scan helps to improve the accuracy and consistency of the overall scan data.

[0117] The following is an embodiment of a device for planning the number of parking spaces based on vehicle size data provided in an embodiment of the present disclosure.

[0123] The planning and matching module is used to plan the parking space length and width information corresponding to the vehicle shape according to the current parking space division strategy when the vehicle shape and size information matches the parking space length and width information corresponding to the current parking space division strategy.
