Technical demands for extraction of significant components from spatial models are increasing as 3D sensors and their application technology has been developed and popularized. In this paper, we propose the 3D point cloud cluster analysis based on the principal component analysis(PCA) of normal-vectors. The distribution of normal vectors depends on a 3D surface shape within the local neighborhood...
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, Difference of Normals (DoN) operator and...
