Abstract

The embodiment of the present invention discloses a method and device for extracting road edges. The method includes: acquiring original point cloud data, and the first heading angle of the target vehicle at the current moment and the second heading angle at the previous moment; judging the first heading angle and Whether the difference of the second heading angle is greater than the preset threshold; if yes, calculate the current turning angle θ of the target vehicle, and convert the original point cloud data twice based on θ to obtain two sets of point cloud data satisfying the preset conditions, and Take two sets of point cloud data as the point cloud data to be processed; if not, convert the original point cloud data based on the preset angle to obtain the target point cloud data that meets the preset conditions, and convert the original point cloud data and the target point cloud data As the point cloud data to be processed; determine the road edge point according to the point cloud data to be processed. By applying the solution provided by the embodiment of the present invention, when the vehicle passes through the intersection section, the edge of the road in the environment where the vehicle is located can be extracted, so as to improve the safety of the vehicle during driving.

Description

technical field [0001] The present invention relates to the technical field of intelligent driving, and in particular, to a method and device for extracting road edges. Background technique [0002] In autonomous driving scenarios, sensing the surrounding environment in advance is an important condition to ensure the safe driving of vehicles. For example, the road edge refers to the important geometric elements on both sides of the road used to define the drivable area. If the road edge can be extracted, it can ensure that the vehicle travels in the drivable area, thereby reducing the probability of accidents. [0003] Known road edge extraction methods can only extract road edges for scenarios where the vehicle's traveling direction is parallel to the road edge, but in practical applications, vehicles may pass through intersections such as intersections. When a vehicle passes an intersection, there will be a road edge that is not parallel to the direction of travel of the ...
