Abstract
A method of mapping 3D point cloud data into 2D surfaces for further efficient temporal coding is described herein. Point cloud global tetris packing utilizes 3D surface patches to represent point clouds and performs temporally consistent global mapping of 3D patch surface data into 2D canvas images. Point cloud global tetris packing includes calculating an accumulated occupancy map and a weight of each patch according to the matched patches.
