| titleOfInvention | Tunnel limit determination method, device electronic device and storage medium |
| abstract | The present disclosure provides a method for determining a tunnel limit, an apparatus electronic device, and a storage medium. The method includes: acquiring first point cloud data corresponding to the area in front of the running of the rail vehicle; filtering the first point cloud data to obtain second point cloud data; wherein the filtering process is used to convert the first point cloud data into the first point cloud data. The parts corresponding to the top and bottom of the tunnel are removed; the second point cloud data is rasterized to obtain a two-dimensional point cloud image corresponding to the second point cloud data; the two-dimensional point cloud image includes several point cloud points; The cloud image is segmented to obtain the point cloud points corresponding to the tunnel wall; in the running direction of the rail vehicle, the point cloud points corresponding to the tunnel wall are divided into several point cloud point groups; for each point cloud point group, the Line fitting is performed on the point cloud points to obtain several fitted straight lines corresponding to several point cloud point groups one-to-one; several fitted straight lines are smoothed to obtain the tunnel boundary. |
