Abstract

The invention is suitable for the technical field of radar measurement and control, and provides a course angle obtaining method and device, equipment and a storage medium, and the course angle obtaining method comprises the steps: obtaining a plurality of reference course angles of a target vehicle, wherein the multiple reference course angles comprise at least two of a course angle obtained according to a principal component analysis algorithm, a course angle obtained through primary track fitting, a course angle obtained through secondary track fitting and a course angle obtained according to a track filtering result; according to the Doppler and azimuth angle of each point in the point cloud of the target vehicle, calculating the variance of the speed of each point in the point cloud corresponding to each reference course angle; and determining the reference course angle corresponding to the minimum variance as the course angle of the target vehicle. By adopting the method and device, the course angle calculation accuracy can be improved.

Description

technical field [0001] The invention belongs to the technical field of radar measurement and control, and in particular relates to a heading angle acquisition method, device, equipment and storage medium. Background technique [0002] Millimeter wave radar has the advantages of high measurement accuracy, rich detection point cloud, all-day, all-weather, etc., and has been widely used in L3 and above assisted driving environment perception. In the process of assisted driving, the maneuvering behaviors of vehicles on the road, such as changing lanes, turning around, and turning, directly affect the path planning and decision-making of the vehicle, and the heading angle is an important factor that characterizes these maneuvering behaviors. According to the size and change trend of the heading angle The maneuvering behavior of the vehicle can be judged. [0003] Currently, there is a problem with the low accuracy of the calculated heading angle. Contents of the invention [...
