Abstract:
1. A computer-implemented method for modeling a polyline boundary from point cloud data, comprising: obtaining, into a memory of a computer, the point cloud data; extracting, using a processor in the computer, one or more boundary cells from the point cloud data; filtering, using the processor in the computer, one or more potential boundary points from the one or more boundary cells; extracting, using the processor in the computer, one or more line segments from the one or more potential boundary points; refining, using the processor in the computer, the one or more line segments; obtaining, using the processor in the computer, a regularized polygon by intersecting the one or more refined line segments; and utilizing, using the processor in the computer, the regularized polygon to reconstruct a building in a building information model.
