Abstract: The present invention relates to the technical field of device calibration, and in particular to an ADAS system calibration guiding method and apparatus, and a vehicle diagnosis device. The method comprises: after a calibration request from a user for an ADAS system of a vehicle is received, prompting the user to select a maintenance scenario for calibrating the ADAS system; according to the maintenance scenario selected by the user, determining the ADAS system to be calibrated in the maintenance scenario, and giving a prompt regarding a calibration tool required for calibrating the ADAS system to be calibrated; giving a prompt regarding a positioning method for the calibration tool: after an indication of the user that the positioning of the calibration tool is completed is received, instructing the vehicle to calibrate the ADAS system to be calibrated; and acquiring a calibration result of the ADAS system to be calibrated, and outputting a calibration analysis report according to the calibration result.

Abstract: The present invention relates to the technical field of automobile maintenance and device calibration, and discloses a device for calibrating a vehicle mounted night-vision video recording apparatus, the device for calibrating the vehicle-mounted night-vision video recording apparatus including a holder assembly and a calibration member. The calibration member is mounted on the holder assembly, the calibration member may move relative to the holder assembly to adjust a height of the calibration member, and the calibration member includes a calibration rod, the calibration rod being disposed horizontally for calibrating the vehicle-mounted night-vision video recording apparatus. In the device for calibrating the vehicle-mounted night-vision video recording apparatus of the present invention, the height of the calibration member is adjustable, and the calibration member includes the horizontally disposed calibration rod.

Abstract: Embodiments of the present invention relate to the field of automobile technologies, and disclose a vehicle detection method, apparatus and a vehicle diagnostic device. The vehicle detection method includes: acquiring at least two vehicle identification numbers of a vehicle; comparing the at least two vehicle identification numbers to obtain a comparison result; and generating a detection result according to the comparison result, and outputting the detection result. Through comparison of a plurality of the vehicle identification numbers, consistency of the vehicle identification numbers is detected. Therefore, a user may be helped to determine whether a vehicle is overhauled or a part thereof is replaced.
