In order to align the time and space of multiple sensors in the ADAS system to ensure data consistency, it is tested through fusion calibration. During the test, the calibration plate used for testing is mostly set on a gantry, which uses a coordinate axis structure to achieve lateral and longitudinal movement of the calibration plate.

[0026] In the utility model, the column 1 is fixed in the inspection workshop of the automobile through the base plate 2, and the geometric calibration plate 8 is installed on the Y-axis motion module 7. When the sensor is calibrated, the X-axis motion module 6 cooperates with the truss 5 to drive the geometric calibration plate 8 to move horizontally, and the Y-axis motion module 7 drives the geometric calibration plate 8 to move longitudinally, so as to adjust the position of the geometric calibration plate 8. The geometric calibration plate 8 provides a stable and known reflectivity target, so that sensors such as laser radar can accurately measure and calibrate it. By measuring and calibrating the geometric calibration plate 8, various parameters of the sensor equipment can be obtained, such as the measurement range, angle resolution, ranging accuracy, etc. When calibrating, the driving component 9 can drive the brush plate 10 to move on the front side of the geometric calibration plate 8, so that the geometric calibration plate 8 is cleaned by the brush plate 10, so as to avoid the blur of the geometric calibration plate 8, which causes the camera or sensor to be unable to accurately capture and identify the marking points on the calibration plate, and further reduce the workload of manual cleaning and reduce the cleaning time;

[0027] It should be noted that the X-axis motion module 6 and the Y-axis motion module 7 adopt a rectangular coordinate robot structure commonly used in the prior art, and can realize driving movement in a rectangular direction.

[0028] Specifically, refer to Figure 2 and Figure 3 The driving assembly 9 includes a bracket 91, a screw rod 93 is provided on the bracket 91 through a motor 92, a slide seat 94 matching its thread is provided on the screw rod 93, and a connecting rod 95 for connecting the brush plate 10 is provided on the slide seat 94. The motor 92 drives the screw rod 93 to rotate so that the slide seat 94 can reciprocate, so that the brush plate 10 can reciprocate on the geometric calibration plate 8, further improving the cleaning effect.

[0029] Specifically, refer to Figure 2 and Figure 4The brush plate 10 includes a fixing plate 101, and a cleaning cotton 103 is arranged on the fixing plate 101 through a slot 102. The fixing plate 101 fixes the cleaning cotton 103, so that the cleaning cotton 103 can always be attached to the front side of the geometric calibration plate 8, and then the geometric calibration plate 8 can be cleaned by the brush plate 10 under the drive of the driving component 9.

[0030] Specifically, refer to Figure 2-Figure 5 A mounting groove 951 is provided near the front end of the connecting rod 95, a limiting block 952 is provided on the mounting groove 951 through a spring 953, a baffle 954 is provided on the connecting rod 95 behind the limiting block 952, and positioning holes 104 matching the connecting rod 95 are provided at both ends of the fixing plate 101. After the connecting rod 95 passes through the positioning holes 104, the limiting block 952 abuts against the front side of the fixing plate 101. When the cleaning cotton 103 on the brush plate 10 needs to be cleaned and replaced, the limit block 952 is pressed to shrink it into the installation groove 951, and then the fixing plate 101 is pulled out from the connecting rod 95. During installation, as the fixing plate 101 is inserted into the connecting rod 95, the limit block 952 is first squeezed into the installation groove 951. As the fixing plate 101 rests on the baffle 954, the limit block 952 pops out under the action of the spring 953 and blocks the front side of the fixing plate 101, so that the brush plate 10 can be easily and quickly installed and disassembled on the connecting rod 95.

[0031] The stopper 952 is wedge-shaped, and the inclined surface of the stopper 952 is facing the front end of the connecting rod 95. The stopper 952 of the wedge-shaped structure can save more effort when installing the fixing plate 101, and there is no need to press the stopper 952 during installation.

[0032] Specifically, refer to Figure 3 and Figure 6 A connecting piece 96 is provided on the rear side of the bracket 91, a rib plate 961 is provided in the middle of the connecting piece 96, and screw holes 962 are provided on the connecting piece 96 at both sides of the rib plate 961. Fasteners are screwed into the screw holes 962 of the connecting piece 96, so that the connection between the bracket 91 and the Y-axis motion module 7 is reinforced by the L-shaped connecting piece 96, and the rib plate 961 improves the strength of the connecting piece 96, so that the drive assembly 9 is installed more firmly.

[0033] Specifically, refer to Figure 1 and Figure 7The mounting assembly 4 includes a mounting plate 41 and a backing plate 42, a damping pad 43 is arranged between the mounting plate 41 and the backing plate 42, a reinforcing plate 44 is arranged on the lower side of the mounting plate 41, and a mounting bolt 45 is arranged on the mounting plate 41. The mounting plate 41 is fixed to the top of the column 1, and then the backing plate 42 is fixed to the truss 5 by the mounting bolt 45. The damping pad 43 can play a role in reinforcement and stability, and the reinforcing plate 44 can play a role in the strength of the mounting assembly 4, so that the truss 5 is more stable when it is installed on the column 1 through the mounting assembly 4.

[0034] Among them, the base plate 2 is detachably installed at the bottom of the column 1 through the mounting part 3, and a mounting hole is opened at the top corner position of the base plate 2. The mounting part 3 can not only strengthen the connection strength between the base plate 2 and the column 1, but also facilitate the disassembly of the base plate 2 and the column 1, thereby facilitating the installation of the gantry.
