Title:
ポイントクラウドマッピング
Document Type and Number:
Japanese Patent JP7093061
Kind Code:
B2
Abstract:
Methods for mapping 3D point cloud data into 2D surfaces are described herein. The methods utilize 3D surface patches to represent point clouds and perform flexible mapping of 3D patch surface data into 2D canvas images. Patches representing geometry and patches representing attributes such as textures are placed in different canvases, where the placement of each patch is done independently for geometry and texture, that is, geometry and texture patches do not need to be co-located, as in conventional point cloud mapping. Furthermore, methods include transformations of the 3D patch when placing it into the 2D canvas, for more efficient packing.
