Extraction of Mountain Feature Line Based on 3D Laser Scanning
This paper applies a Cut-and-Sew algorithm extracting feature line of the mountain based on laser 3D scanning.The mountain is cut at the direction of contour lines.Point cloud data of the cut surface fits curve that project the same plane.Feature points find the curve corresponding to match.Through the connection of feature points,then returning the 3D space to achieve feature line,and the establishment of the formation of the triangular feature line is reconstructed on the mountain.
