When the driver parks the vehicle in the handover area, the laser radar is used to scan it. Since the laser radar needs to identify the size of the vehicle, there are certain requirements for the scanning accuracy of the laser radar, which makes the cost of using laser radar higher.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0048] See also Figures 1 to 7 The present application discloses a vehicle photographing and identifying device for a handover area of ​​a smart parking lot, comprising a profile frame 1, a first camera 2, a second camera 3, a first telescopic frame 4, a second telescopic frame 5, a corresponding sensor assembly 6 and a control system.

[0049] Among them, the profile frame 1 includes a crossbeam 11 and a support rod 12, and the two ends of the crossbeam 11 are respectively connected to the support rods 12 to form an integrated structure. The two support rods 12 are at least partially buried underground to form a supporting structure.

[0050] The first camera 2 is disposed on the cross beam 11 and is rotatably connected to the cross beam 11 for photographing the front, top and rear of the vehicle 7 and forming a first image.

[0051] Specifically, when the vehicle 7 passes in front of the profile frame 1, the first camera 2 shoots the front of the vehicle 7; when the vehicle 7 is located in the frame of the profile frame 1, the first camera 2 rotates a certain angle to form a vertical state and shoots the top of the vehicle 7; when the vehicle 7 is located behind the profile frame 1, the first camera 2 rotates a certain angle to shoot the rear of the vehicle 7.

[0052] Exemplarily, a vehicle photography and identification device for a handover area of ​​a smart parking lot also includes a first stepper motor 21, which is arranged below the crossbeam 11, and the rotating shaft of the first stepper motor 21 rotates along the axial section of the crossbeam 11. The rotating shaft of the first stepper motor 21 is connected to the first camera 2 so that the first camera 2 rotates along the radial section of the crossbeam 11.

[0053] Specifically, the rotation axis of the first stepper motor 21 is parallel to the crossbeam 11 and spaced apart, so that when the first stepper motor 21 is working, the rotation axis can rotate the first camera 2 so that the first camera 2 forms a first angle, a second angle and a third angle in the vertical direction. The first angle is, for example, positive 45 degrees, and the first camera 2 shoots the front of the vehicle 7. The second angle is, for example, 0 degrees, and the first camera 2 shoots the top of the vehicle 7. The third angle is, for example, negative 45 degrees, and the first camera 2 can shoot the rear of the vehicle 7. It should be noted that the rotation angle of the first motor can be adjusted according to the received action signal. For example, different action signals can form different rotation angles.

[0054] One end of the first telescopic frame 4 is arranged on the cross beam 11, and the other end extends to the front of the shaped frame 1. Specifically, the first telescopic frame 4 includes a connecting rod 41 and a first electric telescopic rod 42, one end of the connecting rod 41 is connected to the top surface of the cross beam 11, and the other end of the connecting rod 41 is connected to the fixed end of the first electric telescopic rod 42 on the side wall; the first electric telescopic rod 42 is arranged horizontally, and the telescopic end of the first electric telescopic rod 42 is connected to the second telescopic frame 5.

[0055] It should be noted that the connecting rod 41 is arranged in a vertical direction so that the bottom surface of the connecting rod 41 is connected to the top surface of the crossbeam 11. The top of the connecting rod 41 is connected to the fixed end of the first electric telescopic rod 42. For example, the top side surface of the connecting rod 41 is vertically connected to the fixed end surface of the first electric telescopic rod 42 so that the first electric telescopic rod 42 is arranged horizontally. When the telescopic end of the first electric telescopic rod 42 is connected to the second telescopic frame 5, when the first electric telescopic rod 42 is extended or retracted, it can drive the second telescopic frame 5 to move away from or close to the shaped frame 1.

[0056] Furthermore, a vehicle photographing and identifying device for a handover area of ​​a smart parking lot further includes a second stepper motor 43, which is arranged at the telescopic end of the first electric telescopic rod 42, and the rotating shaft of the second stepper motor 43 is connected to the second telescopic frame 5, so that the second telescopic frame 5 rotates circumferentially in the vertical direction with the second stepper motor 43 as the axis. Specifically, a second stepper motor 43 is arranged on the end face of the telescopic end of the first electric telescopic rod 42, and the second stepper motor 43 is connected to the second telescopic frame 5, so that when the first electric telescopic rod 42 is extended and retracted, the second telescopic frame 5 can be driven to move in the horizontal direction, and when the rotating shaft of the second stepper motor 43 is rotated, it can drive the second telescopic frame 5 to move circumferentially in the vertical direction with the rotating shaft as the axis, so that the second telescopic frame 5 moves from one side of the vehicle 7 to the other side of the vehicle 7. When the second camera 3 is placed on the second telescopic frame 5, the second camera 3 can be used to shoot the sides of the vehicle 7.

[0057] One end of the second telescopic frame 5 is rotatably connected to one end of the first telescopic frame 4 away from the cross beam 11, and the other end is rotatably connected to a sleeve 53. Further, the second telescopic frame 5 includes a second electric telescopic rod 51 and a third stepping motor 52, the fixed end of the second electric telescopic rod 51 is connected to the rotating shaft of the second stepping motor 43; the end surface of the telescopic end of the second electric telescopic rod 51 is connected to the third stepping motor 52; the rotating shaft of the third stepping motor 52 is connected to the sleeve 53, so that the sleeve 53 rotates along the circumferential direction of the second electric telescopic rod 51.

[0058] It should be noted that the second electric telescopic rod 51 can reduce the overall length of the second telescopic frame 5 in the retracted state, so that when the second telescopic frame 5 moves from one side of the vehicle 7 to the other side, the retraction of the second telescopic frame 5 can reduce the overall height of the first telescopic frame 4. In addition, when the second telescopic frame 5 moves from one side of the vehicle 7 to the other side, the shooting direction of the second camera 3 is opposite. Therefore, a third stepper motor 52 is provided at the telescopic end of the second electric telescopic rod 51, and a sleeve 53 is provided on the rotating shaft of the third stepper motor 52. The sleeve 53 is sleeved on the rotating shaft and fixedly connected to the rotating shaft. In this way, when the rotating shaft rotates, the sleeve 53 can be driven to rotate circumferentially, and the second camera 3 fixed on the sleeve 53 will rotate accordingly, so as to adjust the shooting angle of the second camera 3. The rotating shaft of the third stepper motor 52 is coaxial with the axis of the second telescopic frame 5.

[0059] The through-beam sensor assembly 6 is arranged in the traveling direction of the vehicle 7 and is used to generate a sensor signal when the vehicle 7 passes by the through-beam sensor assembly 6 .

[0060] Specifically, the through-beam sensor assembly 6 at least includes a first through-beam sensor 61 , a second through-beam sensor 62 and a third through-beam sensor 63 .

[0061] The first counter-beam sensor 61 is arranged in the traveling direction of the vehicle 7 and is located on the path where the front of the vehicle 7 travels, forming a first sensor signal; the second counter-beam sensor 62 is arranged in the traveling direction of the vehicle 7 and is located on the path where the front windshield of the vehicle 7 travels, forming a second sensor signal; the third counter-beam sensor 63 is arranged in the traveling direction of the vehicle 7 and is located on the path where the front of the vehicle 7 travels, forming a third sensor signal.

[0062] Among them, the second beam sensor 62 is located on one side of the mold frame 1, and the third beam sensor 63 is arranged on the other side of the mold frame 1; the first sensor signal, the second sensor signal and the third sensor signal constitute the sensor signal.

[0063] It should be noted that the first through-beam sensor 61 , the second through-beam sensor 62 and the third through-beam sensor 63 are respectively arranged on the wall of the junction area, so as to fix the first through-beam sensor 61 , the second through-beam sensor 62 and the third through-beam sensor 63 .

[0064] The first through-beam sensor 61, the second through-beam sensor 62 and the third through-beam sensor 63 have different heights when they are arranged on the path of the vehicle 7. The first through-beam sensor 61 needs to sense the vehicle 7 first, so that the front of the vehicle 7 first contacts the rays emitted by the first through-beam sensor 61 when the vehicle 7 is moving, forming a first sensor signal, which is sent to the control system. Next, after receiving the first sensor signal, the control system sends an action signal to the first camera 2 at the initial position (first angle), and sends an action signal to the second camera 3. After receiving the action signal, the first camera 2 starts to take pictures (at the first angle, the first camera 2 is located at the front oblique upper position of the vehicle 7). The first camera 2 takes pictures of the front area of ​​the vehicle 7, such as the front of the vehicle and the front windshield. After receiving the action signal, the second camera 3 starts to take pictures of the side of the vehicle 7. The images taken by the first camera 2 and the second camera 3 are transmitted to the control system respectively.

[0065] Next, the vehicle 7 continues to move. At this time, after receiving the images captured by the first camera 2 and the second camera 3 respectively, the control system sends an action signal to the first telescopic frame 4 and the second telescopic frame 5 (the control system sends an action signal to the first stepper motor 21 so that the first electric telescopic rod 42 retracts, the purpose is to cooperate with the speed of the vehicle 7 to avoid that when the vehicle 7 passes the second corresponding sensor 62, the second camera 3 is still on the vertical plane for capturing the second image, the first electric telescopic rod 42 retracts, and drives the second telescopic frame 5 to move toward the direction of the frame 1. In addition, the first stepper motor 21 rotates according to the preset rotation angle. The first camera 2 is driven to rotate so that the first camera 2 rotates to the second angle; after receiving the action signal, the second stepper motor 43 will rotate according to the preset rotation angle, for example, rotate 270 degrees, so that the second electric telescopic rod 51 connected to the second stepper motor 43 rotates in the vertical direction and circumferentially to the other side of the vehicle 7; after receiving the action signal, the third stepper motor 52 will rotate according to the preset rotation angle, for example, 180 degrees, and the rotation shaft of the third stepper motor 52 drives the sleeve 53 to rotate 180 degrees, so that the second camera 3 on the sleeve 53 rotates 180 degrees synchronously, so as to take pictures of the other side of the vehicle 7). When the vehicle 7 walks to the second pairing sensor 62, the second pairing sensor 62 is triggered, and the second pairing sensor 62 starts to work and sends a second sensor signal to the control system. The control system responds to the second sensor signal and sends an action instruction to the first camera 2 and the second camera 3. The first camera 2 and the second camera 3 take pictures of the top and side of the vehicle 7 respectively to form corresponding images and images.

[0066] Next, the vehicle 7 continues to move along the walking path. After receiving the images captured by the first camera 2 and the second camera 3, the control system issues an action command to the second telescopic frame 5 so that the second telescopic frame 5 is reset to the initial position; and issues an action command to the first stepper motor 21 so that the first stepper motor 21 drives the first camera 2 to be at the third angle. When the movement of the vehicle 7 triggers the third through-beam sensor 63, the third through-beam sensor 63 generates a third sensor signal and sends it to the control system. In response to the third sensor signal, the control system issues an action command to the first camera 2, and the first camera 2 starts to take pictures of the rear of the vehicle 7 to form an image.

[0067] The control system is electrically connected to the through-beam sensor assembly 6, the first camera 2, the second camera 3, the first telescopic frame 4 and the second telescopic frame 5, respectively; wherein the control system is configured to: in response to the sensor signal, send an action signal to the first telescopic frame 4 and the second telescopic frame 5, send an action signal to the first camera 2 and the second camera 3, and receive the first image and the second image.

[0068] Specifically, the control system pre-stores existing image recognition software. When the control system receives the first image and the second image, it performs feature recognition on the first image and the second image so as to determine the size of the vehicle 7 based on the features. It should be noted that the present application does not improve the existing image recognition software or method, nor does it involve software. The function of the control system is the flow of signals, which can be a PLC control system. The program of the control system is also an existing program, and the program has not been improved. The present application also intends to protect the structural part of the device, and does not protect the existing software and programs.

[0069] In one embodiment, a plurality of marking lines (not shown in the figure) are arranged at equal distances on adjacent sides of the two support rods 12. When the first camera 2 and / or the second camera 3 capture an image, if the image contains marking lines, the marking lines facilitate the existing image recognition software to identify the marking lines, so as to quickly determine the size of the vehicle 7. In other words, the plurality of marking lines facilitate the existing image recognition software to identify the marking lines, thereby determining the size of the vehicle 7. Here, it only involves the setting of a plurality of marking lines on the support rods 12, and the judgment of the marking lines in the image recognition software also belongs to the existing recognition method, and the present application does not improve the image recognition method.

[0070] In one embodiment, a vehicle photographing and identifying device for a handover area of ​​a smart parking lot also includes a conveyor belt (not shown in the figure), which is arranged on the path of the vehicle 7 traveling in the handover area, so that when the vehicle 7 reaches the conveyor belt, the conveyor belt transmits the vehicle 7 to move in the direction of the steering frame.

[0071] Specifically, after the driver drives the vehicle 7 to the conveyor belt, the conveyor belt starts to work, driving the vehicle 7 to move in the direction of the shaped frame 1. The conveyor belt can be turned on after the driver parks the vehicle on the conveyor belt, the driver gets off the vehicle, and manually starts the control switch of the conveyor belt so that the conveyor belt starts to work. The conveyor belt can be used to conveniently control the speed of the vehicle 7 so as to leave time for the action of the first telescopic frame 4 and the second telescopic frame 5, thereby avoiding the situation where the driver's speed is too fast and the first telescopic frame 4 and the second telescopic frame 5 are not in place.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
