Abstract
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.
