Indoor point cloud semantic segmentation based on direction perception and hole sampling

Xijiang Chen,
Peng Li,
Bufan Zhao
et al.

Abstract: Most existing point cloud segmentation methods ignore directional information when extracting neighbourhood features. Those methods are ineffective in extracting point cloud neighbourhood features because the point cloud data is not uniformly distributed and is restricted by the size of the convolution kernel. Therefore, we take into account both multiple directions and hole sampling (MDHS). First, we execute spherically sparse sampling with directional encoding in the surrounding domain for every point inside… Show more
