Method and device for determining lane contour line and electronic equipment

The invention provides a method for determining a lane contour line, and relates to the technical fields of automatic driving, high-precision maps and the like. According to the specific scheme, a plurality of reference points are extracted from a trajectory based on the distance between trajectory points in the trajectory; determining at least one normal corresponding to each reference point; moving each reference point for a preset distance along the first direction and the second direction of the corresponding normal to determine at least one group of contour points corresponding to each reference point; and according to the at least one group of contour points corresponding to the plurality of reference points, generating a lane contour line corresponding to the trajectory. Therefore, the lane contour line corresponding to the trajectory line is automatically generated through the at least one group of contour points respectively corresponding to the plurality of reference points in the trajectory line, s
