Abstract

The application being applicable to the technical field of automobiles provides a radar calibration method and a radar. The method comprises the following steps that: relative coordinates of a presetnumber of vehicle body detection points are obtained by detection of a to-be-calibrated radar, wherein the radar is installed at the location of a rearview mirror of the vehicle; on the basis of the relative coordinates, all vehicle body detection points are fitted into one straight line and the straight line is used as a body edge detection line of the vehicle; an included angle between the bodyedge detection line and an actual vehicle body edge line is calculated and the included angle is used as a detection angle; and angle correction is carried out on the radar based on the detection angle. Therefore, the efficiency of correction of the radar at the rear view mirror of the vehicle can be improved effectively.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to a radar calibration method and the radar. Background technique [0002] At present, radar is installed in the position of the rearview mirror in some cars to enhance the blind spot monitoring capability of the rearview mirror. During installation, there will be a fixed angle between the radar and the longitudinal direction of the car body (that is, the installation angle). Due to the deviation of the process during the production of the vehicle, the installation angle of the radar cannot be guaranteed to be completely consistent with the specified installation angle. It is necessary to calibrate the installation angle. Guarantee the actual application effect. [0003] The existing automotive radar calibration technology generally installs a radar simulator or a corner reflector behind the radar and equips a vehicle alignment device for calibration. The calibration ...
