Title:

CAMERA ASSEMBLY, WHEEL POSITIONING SYSTEM AND METHOD FOR POSITIONING WHEELS

Document Type and Number:

WIPO Patent Application WO/2022/033385

Kind Code:

A1

Abstract:

A camera assembly, a wheel positioning system and a method for positioning wheels. The camera assembly (100) comprises a base body (10) and a camera main body (20), wherein the base body (10) is provided with at least two target surfaces (13, 14), the at least two target surfaces (13, 14) are all not in the same plane, and the at least two target surfaces (13, 14) are not in the same plane as that of a lens in the camera main body (20); and the at least two target surfaces (13, 14) are respectively provided with a target element (16), the spatial positional relationship between the target element (16) and the camera main body (20) is known, and the geometric characteristics of the target element (16) are known. Therefore, the position of the camera main body (20) can be determined by acquiring the positions of the target surfaces (13, 14), and the positions of cameras on two sides of a vehicle can be indirectly determined without using a sensor or a preset camera fixing structure, thereby improving the measurement accuracy of calibration calculation.
