Here, cloth simulation filtering (CSF), a verified ground filtering technique used to filter off-ground objects from point cloud in land LiDAR surveys, was adopted and modified. By sequentially filtering the creek points through a hypothetical cloth with an increasingly larger gr...
Inspired by the cloth simulation filter (CSF) proposed by Zhang et al. (2016) for point clouds, we present a novel primitive-oriented cloth simulation algorithm, namely CSF4Geomesh, for the filtering of ground primitives from geomeshes. The main contributions of our method can be exposed as ...
