Abstract

The invention discloses a calibration device and method for a vehicle radar Yaw angle, and the method comprises the steps: a controller obtains a position triggering signal provided by a position triggering module, controls a vehicle straightening mechanism to push a vehicle to move in a second direction according to the position triggering signal, and carries out the calibration of the vehicle radar Yaw angle when the vehicle is determined to move to a first preset position according to the position triggering signal; the vehicle straightening mechanism is controlled to stop pushing the vehicle to move, and the displacement of the vehicle is obtained; a centering stand column displacement mechanism is controlled to push a centering stand column to move in the second direction according to the position trigger signal and the displacement amount of the vehicle until the centering stand column and the plane where the vehicle radar is located are parallel to the first direction, and the centering stand column displacement mechanism is controlled to stop pushing the centering stand column to move; when the centering column and the plane where the vehicle radar is located are parallel to the first direction, the radar coordinates of the centering column are obtained through the vehicle radar, the Yaw angle of the vehicle radar is calibrated according to the radar coordinates of the centering column, and the centering calibration precision and the working efficiency of the vehicle radar are effectively improved.

Description

technical field [0001] Embodiments of the present invention relate to the automatic calibration technology of radar Yaw angles, in particular to a calibration device and method for vehicle radar Yaw angles. Background technique [0002] Smart driving cars are usually equipped with lidar to obtain road condition information through lidar. The yaw angle of the radar is an important parameter for obtaining road condition information (such as the position information of obstacles) when the car is driving. Therefore, it is of great significance to accurately calibrate the yaw angle of the radar to effectively avoid driving accidents. [0003] At present, the laser radar yaw angle is usually calibrated by manual measurement, which has the defects of low work efficiency and low calibration accuracy, and it is difficult to meet the work requirements of the production line and the quality requirements of the product. Contents of the invention [0004] The invention provides a cali...
