[0034] At present, mechanical intelligent parking garages need to match parking spaces according to the size of the vehicle. In order to meet the size of the vehicle, many light curtains or photoelectric devices are installed at the entrance to detect the size and positioning of the vehicle. These detection light curtains and photoelectric devices need to be connected by cables to provide power or feedback signals, and the cables need to be routed through bridges and wired, which makes the construction time longer and costs more labor.
[0035] In order to solve the above problems, the utility model provides a vehicle visual detection system 100, a mechanical garage 200 and a parking lot. Figure 1 A three-dimensional schematic diagram of a first embodiment of a vehicle visual inspection system 100 provided by the utility model; Figure 2 A perspective schematic diagram of a second embodiment of a vehicle visual inspection system 100 provided by the present utility model; Figure 3 for Figure 2 A top view of Figure 4 It is a three-dimensional schematic diagram of a third embodiment of a vehicle visual inspection system 100 provided by the utility model.
[0036] See also Figures 1 to 4 A vehicle visual detection system 100 includes at least one detection system, wherein the at least one detection system includes a first detection system 10, wherein the first detection system 10 is used to be installed at the entrance of a parking lot to detect the size of a vehicle 1 at the entrance of the parking lot; the detection system includes: a first image acquisition device 30, a height vehicle 1 device and a data processing module, wherein the first image acquisition device 30 is used to be installed at a specific height to acquire an image of a parked vehicle 1; the height measuring device 20 is used to be installed at a specific height to measure the height of a parked vehicle 1; the data processing module is electrically connected to the first image acquisition device 30 and the height measuring device 20 to obtain the size information of the parked vehicle 1 according to the information collected by both.
[0037] In the technical solution provided by the utility model, the first image acquisition device 30 is set to acquire images of the vehicle 1, and then the data processing module performs data processing to obtain the size information of the vehicle 1. Compared with the existing light curtain photoelectric solution, only one image acquisition device needs to be installed, and the construction time is short and the difficulty is small.
[0038] It should be noted that at least one detection system is included, which may be only one detection system or multiple detection systems, which is not limited here. The specific implementation form of the first image acquisition device 30 is not limited, and may be a camera, etc., which is not limited here. The data processing module may use AI to process data, or it may use other algorithms to process data. For example, a 5.5*2.1m wireframe 60 is drawn at the entrance of the parking lot, and speed bumps are designed at both ends of the wireframe 60 to slow down the vehicle 1 and let the car slowly pass through the wireframe 60. During the passing process, the vehicle 1 is photographed, and the wireframe 60 is used as a reference to allow the algorithm to calculate the size information of the vehicle 1, etc., which is not limited here.
[0039] The specific height of the first image acquisition device 30 is not limited. Since the first image acquisition device 30 is used to measure the length and width, it needs to take a bird's-eye view of the vehicle 1, so that its height is higher than the height of the vehicle 1. Therefore, the installation height of the first image acquisition device 30 is 3m to 5m. The installation height of the height measuring device 20 is not limited. In this embodiment, a height measuring device 20 is set at 1.5m and 2.05m to detect the height of the vehicle 1 in the horizontal direction.
[0040] After measuring the size of the vehicle 1 and obtaining the size information of the vehicle 1 , the vehicle 1 can be matched with a parking space according to the size information of the vehicle 1 .
[0041] It should be noted that the first image acquisition device 30 is used to measure the length and width. Therefore, when only one first image acquisition device 30 is provided, the vehicle 1 can only be photographed from one angle, which results in that the collected information is relatively single and the judgment of the size of the vehicle 1 may not be accurate. In one embodiment, a plurality of first image acquisition devices 30 are provided, and the plurality of first image acquisition devices 30 are used to be installed at intervals at a specific height of the parking lot entrance. Therefore, by providing a plurality of first image acquisition devices 30, the vehicle 1 can be photographed at different angles, so that the accuracy of the detection result is higher.
[0042] Furthermore, the specific implementation form of the height detection device is not limited, and it can be in the form of an image acquisition device. For example, an image acquisition device is set up at 1.5m and 2.05m respectively to detect the height of the vehicle 1 in the horizontal direction. By taking pictures horizontally by the image acquisition device, the vehicle 1 can be photographed, and it can be determined that the height of the vehicle 1 is greater than the installation height of the image acquisition device, thereby realizing the detection of the height of the vehicle 1. Therefore, the height measuring device 20 includes a second image acquisition device 21. Of course, the height measuring device 20 can also include a photoelectric measuring device 22; or, the height measuring device 20 includes a light curtain measuring device, which is not limited here.
[0043] After obtaining the size information of vehicle 1, the data processing device is used to match the parking space according to the size of vehicle 1. In order to guide vehicle 1 to the matching parking space, the vehicle visual detection system 100 also includes a guiding device, and the guiding device is used to guide vehicle 1 to the matching parking space. Specifically, the specific implementation form of the guiding device is not limited. It can be in the form of a signal light. For example, signal lights are set in the parking lot, and the corresponding control part signal lights are lit to guide vehicle 1 to the designated parking space. It can also be in the form of a display screen, and the matching parking space is displayed on the display screen to guide vehicle 1 to the designated parking space, etc., which is not limited here.
[0044] Alternatively, the vehicle visual detection system 100 may be connected to a garage management system. The management system may allocate parking spaces based on the parameters transmitted by the vehicle visual detection system 100, and immediately publish the information "the garage number where the vehicle 1 is to be parked" on a roadside guide sign that the vehicle 1 is to pass, to guide the vehicle 1 into the garage.
[0045] When the vehicle 1 arrives at the mechanical garage 200, the size of the vehicle 1 needs to be measured again. For this purpose, the at least one detection system also includes a second detection system 50. The second detection system 50 is used to be installed at the entrance of the mechanical garage 200 in the parking lot. It can be understood that the data processing module of the second detection system 50 and the data processing module of the first detection system 10 can be shared or separately arranged, which is not limited here.
[0046] Furthermore, in order to take photos of the vehicle 1 at multiple angles, the second detection system 50 is provided with multiple first image acquisition devices 30 .
[0047] One or more cameras that take photos downward are installed in each entrance of the mechanical garage 200. The cameras form the first image acquisition device 30 to detect the length and width of the vehicle 1, and a 5.5*2.1m wireframe 60 is drawn on the ground. The front wheels of the vehicle 1 are parked within the limit, and a camera (or photoelectric or light curtain) is set up at a height of 1.55m and 2.05m at a suitable position in the garage. The cameras form the height measurement device 20 to measure the height of the vehicle 1 in the horizontal direction; these collected parameters are bound to the license plate and transmitted to the management computer. The management system allocates a parking space based on the information of the vehicle 1. When the vehicle 1 parks in the entrance, the device will send the vehicle 1 to the parking space allocated by the system; these collected parameters are bound to the license plate and transmitted to the management computer. The management system allocates a parking space based on the information of the vehicle 1. When the vehicle 1 parks in the entrance, the device will send the vehicle 1 to the parking space allocated by the system.
[0048] To achieve the above purpose, the present application further proposes a mechanical garage 200, wherein a second detection system 50 is provided at the entrance of the mechanical garage 200, and the second detection system 50 includes:
[0049] A first image acquisition device 30 is installed at a specific height of the mechanical garage 200 to acquire images of the vehicle 1 parked at the entrance of the mechanical garage 200;
[0050] a height measuring device 20 installed at a specific height of the mechanical garage 200 to measure the height of the vehicle 1 parked at the entrance of the mechanical garage 200; and
[0051] The data processing module is electrically connected to the first image acquisition device 30 and the height measurement device 20 to obtain the size information of the parked vehicle 1 according to the information collected by both.
[0052] In the technical solution provided by the utility model, the first image acquisition device 30 is set to acquire images of the vehicle 1, and then the data processing module performs data processing to obtain the size information of the vehicle 1. Compared with the existing light curtain photoelectric solution, only one image acquisition device needs to be installed, and the construction time is short and the difficulty is small.
[0053] Furthermore, in order to park the vehicle 1 at a specific position, thereby facilitating the vehicle visual inspection system 100 to detect the size of the vehicle 1, a wireframe 60 for parking the vehicle 1 is provided at the entrance of the mechanical garage 200, so that the vehicle 1 can be positioned and parked. Furthermore, a limit, such as a limit protrusion, can be provided within the wireframe 60 to limit the vehicle 1.
[0054] To achieve the above objectives, the present application also proposes a parking lot, including the vehicle visual detection system 100 as described above.
[0055] Optionally, a wire frame 60 for parking vehicles 1 is provided at the entrance of the parking lot.
