摘要： The disclosure relates to the technical field of automobile maintenance and repair as well as device calibration, and in particular, to a bracket apparatus. The bracket apparatus includes a base, a vertical rod and a clamping assembly. One end of the vertical rod is mounted to the base. The clamping assembly is mounted to the vertical rod. The clamping assembly includes a sliding member, a push rod assembly, a handle and an elastic member. One end of the sliding member is sleeved on the vertical rod. The sliding member is movable along the vertical rod. An other end of the sliding member is configured to carry a calibration element. The push rod assembly can be movably mounted to the sliding member in a preset direction. Two ends of the elastic member respectively abut against an inner wall of the sliding member and the push rod assembly. The elastic member can drive one end of the push rod assembly to be tightly pressed against the vertical rod. The sliding member is fixed to the vertical rod to prevent the sliding member from free falling and smashing. In addition, the handle is rotatably mounted to the sliding member to drive one end of the push rod assembly to be removed from contact with the vertical rod, so that the sliding member is slidable freely along the vertical rod. Therefore, the height of the calibration apparatus hung on the sliding member can be adjusted as needed, to meet different height requirements and calibration requirements.

摘要： A vehicle detection system and a vehicle detection method. The vehicle detection system comprises a support (100), machine vision modules (200), a failure sensor (300), and a controller (400). Each machine vision module (200) comprises at least one image acquisition device (210), and the image acquisition device (210) comprises an image acquisition sensor (212) which is used for obtaining related parameters of hardware to be detected of a vehicle. The failure sensor (300) is used for acquiring position change information of the image acquisition sensor (212) and outputting a motion parameter signal comprising the position change information. The controller (400) is used for determining, according to the motion parameter signal, whether the position of the image acquisition sensor (212) needs to be calibrated. In the using process of the vehicle detection system, the controller (400) can determine in real time whether the position of the image acquisition sensor (212) needs to be calibrated, so as to avoid a miscorrection caused by detecting and correcting the vehicle without precalibration after the measurement and calculation precision of the vehicle detection system is reduced, thereby avoiding the occurrence of dangerous accidents.
