Abstract: A camera assembly for a wheel positioning system includes a base body and a camera main body. The base body is provided with target surfaces which are not in the same plane and are not in the same plane as that of a lens in the camera main body. The target surfaces are respectively provided with target elements, the spatial positional relationship between the target element and the camera main body is known, and the geometric characteristics of the target element are known. Therefore, the position of the camera main body can be determined by acquiring the positions of the target surfaces, 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.

Abstract: The present invention discloses a tire pressure sensor identification method, a related apparatus and system. A tire pressure sensor identification apparatus in the present invention includes a storage module configured to store identity information of a tire pressure sensor, a communications module configured to communicate with an electronic control unit (ECU) of a vehicle, a processing module and a radio frequency transmission module configured to output identity information. The tire pressure sensor identification apparatus may output the stored identity information to a corresponding vehicle, so that the vehicle can still identify the tire pressure sensor even if the tire pressure sensor is not in an activated state. It is convenient for a user to perform a uniform identification operation after uniformly collecting the identity information, thereby improving identification efficiency of the tire pressure sensor.
