Abstract

The invention discloses an ultrasonic radar self-adaptive calibration device which comprises a rotating support used for fixing an ultrasonic radar, a fixing support is arranged on the periphery of the rotating support, and the rotating support is arranged in the center of the fixing support through cooperation of a concave-convex structure. The outer side of the fixed support is connected with an installation support, a stepping motor is arranged in the installation support, a rotating shaft of the stepping motor is connected with a gear, the installation support is provided with a pressing device, a rack is arranged between the pressing device and the gear, and one end of the rack is rotationally connected with the rotating support. The device further comprises a processor, and the processor is electrically connected with the ultrasonic radar and the stepping motor. The device improves the calibration efficiency of the ultrasonic radar in the whole vehicle assembly.

Description

technical field [0001] The invention relates to the field of ultrasonic radar calibration, in particular to an ultrasonic radar self-adaptive calibration method and device. Background technique [0002] After the ultrasonic radar is assembled on the vehicle, the vehicle will be calibrated. During the calibration process, if there is a problem, the common method is to modify the software parameters, adjust the radar height, and adjust the radar elevation angle. If the radar height and elevation angle need to be adjusted, the environmental components (such as front and rear protection) need to be changed at the same time, which will bring a lot of extra work and cost. Contents of the invention [0003] The object of the present invention is to provide an ultrasonic radar adaptive calibration method and device to improve the efficiency of ultrasonic radar calibration during vehicle assembly. [0004] In order to achieve the above object, the present invention provides the f...
