Abstract:
We propose a workflow for extracting geometric primitives, including linear, planar, and cylindrical objects, from point clouds of the construction site, using a novel segmentation- and recognition-based strategy. The entire point cloud is first organized by an octree-based voxel structure. The proposed voxel- and graph-based segmentation is conducted by aggregating connected adjacent voxels in a fully connected local affinity graph, the weighted edges of which consider their saliencies simultan...     »
