Example Embodiment
[0053] Such as Figure 1 to 7 As shown, a laser point cloud-based interactive extraction method for left and right contours of lane lines includes the following steps:
[0054] S1. On the laser point cloud operating platform, manually specify the starting points of N lane lines, N> =1, select manual guided collection or trajectory guided collection; when selecting trajectory guidance, the source data needs to be accompanied by the trajectory data matched with the point cloud as the guide point set; when selecting manual guided collection, you need to enter another along the extension direction of the lane line Guide point
[0055] S2, at each starting point, execute S3~S6 in sequence;
[0056] S3. Find the guide point closest to the starting point, obtain the guide point heading, and calculate the left guide line and the right guide line to the left and right from the starting point along the heading, and calculate the left guide line and the right guide line respectively. The guid...
