Technical Field
[0001] This utility model relates to the field of four-wheel alignment technology for automobiles, and more particularly to a contactless positioning device and a contactless positioning system. Background Technology
[0002] Traditional 3D four-wheel alignment systems for automobiles mostly use single-camera or dual-camera ranging solutions to obtain tire alignment parameters through 3D image analysis. However, traditional 3D four-wheel alignment systems for automobiles have the following problems: 1) Wheel clamps must be installed on the car wheels. Installing wheel clamps is not only time-consuming, but may also damage the tires and rims. That is, all traditional 3D four-wheel alignment machines currently require four wheel clamps and four targets to be installed on the tires of the car to be inspected, which makes the installation time-consuming; moreover, there is a risk of damage to the tires and rims when installing wheel clamps. 2) Large measurement error, meaning that single-camera or dual-camera solutions cannot construct complete and sufficiently accurate 3D cloud data, and the calculation of key angles of tire positioning parameters such as toe angle, camber angle and caster angle relies on empirical formulas. Utility Model Content
[0003] This utility model provides a contactless positioning device and a contactless positioning system, which aims to solve the problem that the use of existing 3D four-wheel alignment machines for automobiles requires the installation of four wheel clamps and four targets on the tires of the vehicle to be tested, resulting in time-consuming installation and reduced four-wheel alignment efficiency.

[0013] Please see Figures 1 to 3 , Figure 1 A schematic block diagram of a contactless positioning device provided in an embodiment of the present invention; Figure 2 This is a schematic diagram of the structure of the contactless positioning instrument in a contactless positioning device provided in an embodiment of the present invention; Figure 3 This is a schematic diagram of the structure of the contactless positioning instrument in another embodiment of the present invention. Figures 1 to 3 As shown, the contactless positioning device 1 provided in this embodiment of the present invention includes: at least one contactless positioning module 10, and each contactless positioning module 10 includes two contactless positioning devices 100 arranged opposite each other; each contactless positioning device 100 includes a positioning device column 110, a control board 120, a binocular camera module 130, and a laser head module 140; the control board 120 is disposed inside the positioning device column 110; the laser head module 140 includes a plurality of laser heads arranged sequentially from top to bottom along the longitudinal vertical direction of the positioning device column 110 on the front panel of the positioning device column 110, and each of the plurality of laser heads is connected to the control board 120; the first camera 131 and the second camera 132 in the binocular camera module 130 are respectively disposed at both ends of the laser head module 140, and both the first camera 131 and the second camera 132 are connected to the control board 120.
[0014] In this embodiment, when there is a need for four-wheel alignment of a vehicle, the contactless positioning device can be installed and used in corresponding locations such as car repair shops, car production lines, and car maintenance shops. When installing the contactless positioning device at the current location, a leveling operation is first required, ensuring that the longitudinal axis of each contactless positioning device 100 in the contactless positioning module 10 is parallel to the direction of gravity after installation and fixation. Next, the front panel of each contactless positioning device in the contactless positioning module 10 needs to be aligned with the front panel of another contactless positioning device that requires alignment. For example, aligning the binocular camera module on the front panel of one contactless positioning device with the binocular camera module on another contactless positioning device, and aligning the laser head module on the front panel of one contactless positioning device with the laser head module on another contactless positioning device. To ensure the acquisition effect of the first camera 131 and the second camera 132 in the binocular camera module 130, if the vertical line of the front panel of the contactless positioning device is taken as the 0° angle reference line, the minimum requirement for the image acquisition field of view of the first camera 131 and the second camera 132 is -60° to 60° (of course, it is better to use a camera with a larger image acquisition field of view). To ensure that the detection area of the laser head module 140 covers the tires and rims of the car, the number of laser heads included in the laser head module 140 is 1 to 20 (preferably 6, 7, 8, 10, etc.). In specific implementations, the laser head module 140 can be an infrared laser head module, an ultraviolet laser head module, a blue laser head module, etc.
[0015] Furthermore, when installing the two directly opposite contactless positioning devices 100 in each contactless positioning module 10, the distance between the two contactless positioning devices must be greater than the sum of the car's wheelbase and a preset distance threshold (such as 0.8 meters, 1 meter, 1.2 meters, 1.5 meters, etc. These distance values are not exhaustive but rather list some practical values that can be customized according to the actual dimensions of the installation site). When a car requiring four-wheel alignment enters the detection area corresponding to the two directly opposite contactless positioning devices 100 in the contactless positioning module 10, ideally, if the two front wheels of the car enter the detection area first, the distance between the car's left front wheel and one contactless positioning device is equal to the distance between the car's right front wheel and the other contactless positioning device. However, if the actual parking distance does not reach this ideal state, it will not affect the subsequent four-wheel alignment operation.
[0016] Referring to the example above, when a car requiring four-wheel alignment is parked in the detection area, the binocular camera module 130 in the contactless alignment device with the front panel facing the left front wheel can detect that the left front wheel is completely within its image acquisition range. Then, multiple parallel linear lasers emitted by the laser head module 140 (each laser containing multiple cross-shaped or grid-shaped infrared feature spots) perform an infrared scan of the tire and rim of the left front wheel. The binocular camera module 130 then acquires the feature image corresponding to the left front wheel and the multiple infrared feature spots on it. Finally, the binocular vision algorithm of the binocular camera module 130 identifies the infrared feature spots in the feature image, thereby obtaining the point cloud data of the left front wheel. Because the laser head module emits laser light, it can automatically and actively supplement the light to overcome ambient light interference and works stably in both strong and weak light conditions. Through the laser head module and binocular camera module in the contactless alignment device, a three-dimensional wheel data acquisition method combining binocular vision and structured light is constructed. Simultaneously, the binocular camera module 130 in the contactless positioning device facing the right front wheel on the front panel can detect that the right front wheel of the car is completely within its image acquisition range. Then, multiple parallel linear lasers emitted by the laser head module 140 perform infrared scanning of the tire and rim of the right front wheel. The binocular camera module 130 then acquires feature images corresponding to multiple infrared feature spots on the right front wheel. The binocular vision algorithm of the binocular camera module 130 then performs infrared feature spot recognition on the feature images, thereby obtaining the right front wheel point cloud data. Subsequently, the processor on the control board 120 can combine the left and right front wheel point cloud data to quickly model the three-dimensional models of the left and right front wheels of the car. Then, based on the three-dimensional models of the left and right front wheels, some key data can be determined, and the toe angle, camber angle, and caster angle corresponding to the front wheels of the car can be calculated.
[0017] To better understand the process of determining the toe angle, camber angle, and caster angle of a car's front wheels, the definition of each angle is briefly introduced below. The toe angle is the angle between the front of the wheel and the car's centerline when viewed from directly above the car; the camber angle is the angle between the wheel's centerline and the vertical line to the ground when viewed from the front of the car; and the caster angle is the angle at which the steering kingpin tilts backward when viewed from the side of the car.
[0018] In one embodiment, as a first embodiment of the contactless positioning device, such as Figures 1-4 As shown, the number of the at least one contactless positioning module 10 is one, and the two contactless positioning devices in a contactless positioning module are respectively referred to as the first contactless positioning device 101 and the second contactless positioning device 102. When the first contactless locator 101 and the second contactless locator 102 are facing each other, the front panel of the first contactless locator 101 and the front panel of the second contactless locator 102 are facing each other. The first binocular camera module 1301 on the front panel of the first contactless positioning device 101 is directly opposite to the second binocular camera module (not shown or labeled due to viewing angle) on the front panel of the second contactless positioning device 102. The first laser head module 1401 on the front panel of the first contactless positioning device 101 is directly opposite to the second laser head module (not shown or labeled due to viewing angle) on the front panel of the second contactless positioning device 102.
[0019] In this embodiment, as the first embodiment of the contactless positioning device, it is suitable for use scenarios with low total setup cost of the device. In this use scenario, only the front or rear wheels of the car can be collected for contactless positioning at one time, and a total of two detection operations are required to complete the positioning operation of all four wheels of the car.
[0020] Specifically, the first laser head module 1401 includes eight laser heads arranged sequentially from top to bottom along the longitudinal vertical direction of the positioning column of the first contactless positioning device 101 on the front panel of the first contactless positioning device 101. The detection range of the laser emitted by each laser head forms a straight line segment with a length greater than the diameter of the car wheel and a direction parallel to the horizontal plane. Because the eight laser heads in the first laser head module 1401 are set at different heights relative to the ground, the area covered by the eight laser heads covers most of the area of the wheel to be detected, enabling effective infrared scanning to determine the wheel's point cloud data. Similarly, the second laser head module includes eight laser heads arranged sequentially from top to bottom along the longitudinal vertical direction of the positioning column of the second contactless positioning device 102 on the front panel of the second contactless positioning device 102. It also covers most of the area of the wheel to be detected, and can also effectively perform infrared scanning to determine the wheel's point cloud data.
[0021] Specifically, the two cameras included in the first binocular camera module 1301 must be positioned at opposite ends of the first laser head module 1401, with one camera above the highest laser head in the first laser head module 1401 and the other below the lowest laser head in the first laser head module 1401. Similarly, the two cameras included in the second binocular camera module must be positioned at opposite ends of the second laser head module. Therefore, this structural arrangement allows the contactless positioning module to detect at least two front wheels or two rear wheels of a vehicle.
[0022] In one embodiment, as a second embodiment of the contactless positioning device, such as Figures 1-3 and Figure 5 As shown, there are two contactless positioning modules 10, and the four contactless positioning devices in the two contactless positioning modules are respectively denoted as the first contactless positioning device 101, the second contactless positioning device 102, the third contactless positioning device 103 and the fourth contactless positioning device 104. When the first contactless locator 101 and the second contactless locator 102 are facing each other, and the third contactless locator 103 and the fourth contactless locator 104 are facing each other, the front panel of the first contactless locator 101 and the front panel of the second contactless locator 102 are facing each other, and the front panel of the third contactless locator 103 and the front panel of the fourth contactless locator 104 are facing each other. The first binocular camera module 1301 on the front panel of the first contactless positioning device 101 is directly opposite to the second binocular camera module (not shown or labeled due to viewing angle) on the front panel of the second contactless positioning device 102. The first laser head module 1401 on the front panel of the first contactless positioning device 101 is directly opposite to the second laser head module (not shown or labeled due to viewing angle) on the front panel of the second contactless positioning device 102. The third binocular camera module 1303 on the front panel of the third contactless positioning device 103 is directly opposite to the fourth binocular camera module (not shown or labeled due to viewing angle) on the front panel of the fourth contactless positioning device 104. The third laser head module 1403 on the front panel of the third contactless positioning device 103 is directly opposite to the fourth laser head module (not shown or labeled due to viewing angle) on the front panel of the fourth contactless positioning device 104.
[0023] In this embodiment, as a second embodiment of the contactless positioning device, it is suitable for use scenarios with rapid detection requirements. In this use scenario, only the four wheels of the car can be collected for contactless positioning at one time, and a total of one detection operation is required to complete the positioning operation of the four wheels of the car.
[0024] Specifically, the first laser head module 1401 includes eight laser heads arranged sequentially from top to bottom on the front panel of the first contactless positioning instrument 101 along the longitudinal vertical direction of the positioning instrument column. The detection range of the laser beam emitted by each laser head forms a straight line segment with a length greater than the diameter of the car wheel and a direction parallel to the horizontal plane. Since the first laser head module 1401 includes eight laser heads with different setting heights relative to the ground, the area covered by the eight laser heads of the first laser head module 1401 covers most of the area of the wheel to be detected, which can effectively perform infrared scanning to determine the point cloud data of the wheel. Similarly, the second laser head module includes eight laser heads arranged sequentially from top to bottom along the longitudinal vertical direction of the positioning column of the second contactless positioning device 102 on the front panel of the second contactless positioning device 102, which also covers most of the area of the wheel to be detected and can effectively perform infrared scanning to determine the point cloud data of the wheel; the third laser head module 1403 includes eight laser heads arranged sequentially from top to bottom along the longitudinal vertical direction of the positioning column of the third contactless positioning device 103 on the front panel of the third contactless positioning device 103, which also covers most of the area of the wheel to be detected and can effectively perform infrared scanning to determine the point cloud data of the wheel; the fourth laser head module includes eight laser heads arranged sequentially from top to bottom along the longitudinal vertical direction of the positioning column of the fourth contactless positioning device 104 on the front panel of the fourth contactless positioning device 104, which also covers most of the area of the wheel to be detected and can effectively perform infrared scanning to determine the point cloud data of the wheel.
[0025] Specifically, the two cameras in the first binocular camera module 1301 are positioned at opposite ends of the first laser head module 1401, with one camera above the highest laser head in the first laser head module 1401 and the other below the lowest laser head in the first laser head module 1401. Similarly, the two cameras in the second binocular camera module are positioned at opposite ends of the second laser head module, the two cameras in the third binocular camera module 1303 are positioned at opposite ends of the third laser head module 1403, and the two cameras in the fourth binocular camera module are positioned at opposite ends of the fourth laser head module. Therefore, this structural arrangement allows the contactless positioning module to simultaneously detect all four wheels of a vehicle within its detection area.
[0026] In one embodiment, as a first embodiment of the positioning column in a contactless positioning device, such as Figures 1-2As shown, the positioning column 110 in the contactless positioning device 100 includes a column body 111 and a mounting base 112; the mounting base 112 is connected to the bottom of the column body 111, and the mounting base 112 is used to install the column body 111 on the installation site.
[0027] In this embodiment, as the first embodiment of the positioning column 110 in the contactless positioning device 100, whether the contactless positioning device includes two or four contactless positioning devices 100, the positioning column 110 of each contactless positioning device 100 can adopt the above structure. In specific implementation, the mounting base 112 can include a lower mounting plate 1121 and an upper mounting plate 1122 (generally the area of the upper mounting plate is smaller than that of the lower mounting plate). The lower mounting plate 1121 is fixed on the ground of the installation site, and the upper mounting plate 1122 is screwed to the lower mounting plate by multiple adjustable screws (that is, the lower mounting plate 1121 has screw holes corresponding to the multiple adjustable screws respectively). When the column body 111 is fixedly connected to the upper end face of the upper mounting plate 1122, the longitudinal axis of the column body can be ensured to be perpendicular to the ground of the installation site by adjusting the depth of the multiple adjustable screws entering the corresponding screw holes in the lower mounting plate.
[0028] In one embodiment, such as Figure 1 and Figure 2 As shown, a level 1111 is also provided at the top of the column body 111.
[0029] In this embodiment, this structural setup allows each contactless positioning device 100 to be installed horizontally via the level indicator 1111, which also facilitates the subsequent collection of more accurate wheel data by the binocular camera module and laser head module mounted on the column body.
[0030] In one embodiment, as a second embodiment of the positioning column in a contactless positioning device, such as Figure 1 and Figure 3 As shown, the positioning column 110 in the contactless positioning device 100 includes a column body 111 and an elevating base column 113; the elevating base column 113 is connected to the bottom of the column body 111, and the bottom of the elevating base column 113 is fixedly installed on the site to be installed.
[0031] In this embodiment, as a second embodiment of the positioning column 110 in the contactless positioning device 100, regardless of whether the contactless positioning device includes two or four contactless positioning devices 100, the positioning column 110 of each contactless positioning device 100 can adopt the above-described structure. Furthermore, the horizontal installation method of the raised base column 113 can refer to the first embodiment of the positioning column 110. That is, it is necessary to ensure that the raised base column 113 is first horizontally installed on the ground of the installation site. After the column body 111 is installed, the level indicator 1111 on its top is used to indicate that it is installed horizontally. In the second embodiment of the positioning column 110 in the contactless positioning device 100, if the contactless positioning device includes four contactless positioning devices 100, a car lift platform needs to be installed in the rectangular area formed by the four contactless positioning devices on the installation site. After the car to be tested stops on the car lift platform, the car is raised, thereby performing four-wheel alignment detection in the raised state.
[0032] In one embodiment, such as Figures 1-3 and Figure 4 As shown, the bottom end of the first contactless positioning device 101 is slidably connected to the first slide rail (not shown), and the bottom end of the second contactless positioning device 102 is slidably connected to the second slide rail (not shown); the first slide rail and the second slide rail are both fixedly installed on the installation site and arranged in parallel.
[0033] In this embodiment, as a first embodiment of a contactless positioning device, and including a first contactless positioning device 101 and a second contactless positioning device 102, in order to facilitate the adjustment of the stopping positions of the first contactless positioning device 101 and the second contactless positioning device 102 on the ground, the bottom end of the first contactless positioning device 101 can be slidably connected to a first slide rail and the bottom end of the second contactless positioning device 102 can be slidably connected to a second slide rail, wherein the first slide rail and the second slide rail can be commonly used linear slide rails.
[0034] In one embodiment, such as Figures 1-3 and Figure 5 As shown, the bottom end of the third contactless positioning device 103 is slidably connected to the third slide rail (not shown), and the bottom end of the fourth contactless positioning device 104 is slidably connected to the fourth slide rail (not shown); the third slide rail and the fourth slide rail are both fixedly installed on the installation site and arranged in parallel.
[0035] In this embodiment, as a first embodiment of a contactless positioning device, including a first contactless positioning device 101, a second contactless positioning device 102, a third contactless positioning device 103, and a fourth contactless positioning device 104, the first and second contactless positioning devices 101 and 102 can be fixedly installed on the ground. The bottom end of the third contactless positioning device 103 is slidably connected to a third slide rail, and the bottom end of the fourth contactless positioning device 104 is slidably connected to a fourth slide rail. The third and fourth slide rails can also be commonly used linear slide rails. When the body length of some vehicles to be detected is relatively long, the third contactless positioning device 103 can slide on the third slide rail, and the fourth contactless positioning device 104 can slide on the fourth slide rail, making the distance between the third contactless positioning device 103 and the first contactless positioning device 101 longer, and the distance between the fourth contactless positioning device 104 and the second contactless positioning device 102 longer, thereby adapting to the current vehicle body length.
[0036] In one embodiment, such as Figure 6 As shown, the contactless positioning device also includes a processing host 2, which is connected to the control board 120 in each contactless positioning instrument 100 in each contactless positioning module 10 via wired or wireless communication.
[0037] In this embodiment, if the processor in the control board 120 of the contactless positioning device 100 has high performance, after the processor 120 in the contactless positioning device collects the feature image including the wheel itself and multiple infrared feature spots from the binocular camera module 130, it performs infrared feature spot recognition on the feature image locally in conjunction with the binocular vision algorithm of the binocular camera module 130, thereby obtaining wheel point cloud data corresponding to the wheel. If the processor in the control board 120 of the contactless positioning device 100 has low performance and cannot perform fast data processing, the processing host can obtain the feature image including the wheel itself and multiple infrared feature spots collected by the binocular camera module 130 and transmit it to the processing host 2. The processor in the processing host, with higher performance, performs infrared feature spot recognition on the feature image in conjunction with the binocular vision algorithm of the binocular camera module 130, thereby obtaining wheel point cloud data corresponding to the wheel. Moreover, the processing host can further combine the wheel point cloud data of each wheel of the car to quickly model the three-dimensional model of each wheel of the car. Then, by combining the three-dimensional model of each wheel of the car, some key data can be determined, and the toe angle, camber angle and caster angle corresponding to each wheel of the car can be calculated.

The backend server is communicatively connected to the contactless positioning device, and therefore possesses at least all the beneficial effects brought about by the technical solutions of the foregoing embodiments, which will not be elaborated upon here. In specific implementations, the backend server may be an edge server or a cloud server, etc.
[0040] This invention provides a contactless positioning device and a contactless positioning system.

Each contactless positioning instrument includes a positioning instrument column, a control board, a binocular camera module, and a laser head module.
