OUTLINE APPROXIMATION FOR POINT CLOUD OF BUILDING

摘要

A method, apparatus, system, and computer program product provide the ability to model a polyline boundary from point cloud data. Point cloud data is obtained and boundary cells are extracted. Potential boundary points are filtered from the boundary cells. Line segments are extracted from the potential boundary points and refined. A regularized polygon is obtained by intersecting the refined line segments.

1. A computer-implemented method for modeling a polyline boundary from point cloud data, comprising:
obtaining the point cloud data; extracting one or more boundary cells from the point cloud data; filtering one or more potential boundary points from the one or more boundary cells; extracting one or more line segments from the one or more potential boundary points; refining the one or more line segments; and obtaining a regularized polygon by intersecting the one or more refined line segments.
