Method and device for calibrating installation angle of vehicle-mounted radar and related equipment

Abstract

The invention discloses a method and device for calibrating an installation angle of a vehicle-mounted radar, and related equipment. The method for calibrating the installation angle of the vehicle-mounted radar comprises the following steps of acquiring the target information of a plurality of objects detected by the vehicle-mounted radar, wherein the target information comprises a target distance between the object and the vehicle and a target angle between the object and the vehicle; selecting at least one group of target objects from a plurality of objects according to the target distanceand the target angle, each group of target objects including two objects satisfying a preset condition; and calculating an actual installation angle of the vehicle-mounted radar according to the target distance and the target angle of each object in the at least one group of target objects. The method is advantaged in that dynamic calibration of the radar installation angle is achieved when the vehicle is subjected to road testing, so steps of the whole vehicle manufacturing process of the vehicle can be reduced, the time and labor can be effectively saved, and vehicle assembly production efficiency is improved.

Description

technical field [0001] The present invention relates to the application field of vehicle radar, in particular to a method, device, vehicle and computer-readable storage medium for calibrating the installation angle of vehicle radar. Background technique [0002] In Advanced Driver Assistant Systems (ADAS for short), Adaptive Cruise Control (ACC for short) is a commonly used auxiliary function. Its specific working principle is to measure the distance of the vehicle in front in real time through the on-board radar, compare the speed of its own vehicle with the speed of the vehicle in front, and at the same time control the power system of the vehicle such as accelerator and brake, so that the vehicle always maintains a constant distance from the vehicle in front. safe distance. Therefore, the role of the vehicle radar is very important in the realization of the ACC function. The radar calibration is the basis for the radar to measure the target azimuth, and the accuracy of t...

Problems solved by technology

[0004] But the current problem is: because the installation of the radar on the vehicle is equivalent to adding a process in the vehicle manufacturing process, this process includes the static calibration of the radar installation and installation angle, so it must be statically calibrated to confirm that the installation angle is correct before passing the test. However, the static calibration method for the radar installation angle in the related art will increase the static calibration process of the installation angle in the radar installation process of the vehicle manufacturing process, thereby affecting the vehicle assembly production efficiency, and in the calibration During the process, if the radar installation angle deviates, it needs to be recalibrated to correct the installation angle, which wastes time and manpower, resulting in low efficiency
