As a 3D sensor and its application technology had been developed and popularized, technical demands for extraction of significant components from spatial models are increasing.Acquiring spatial information from a point cloud is very important and fundamental technique to process a large number of points.To acquire spatial information from the point cloud, we focused on a slant of a normal vector to obtain a geometric shape from the point cloud.
In this paper, we propose 3D point cloud cluster analysis based on principal component analysis of normal vectors distribution.Our experimental results showed that the proposed method is robust to noises or spatial holes.Cluster analysis of this normal vector distribution indicated that eigenvalues are affected by a local neighborhood. |
