Recovering scene structures from scattered surface points

摘要

Given scattered points from range or volumetric images, methods for the recovery of scene structures are described. The structures are represented by rational Gaussian surfaces. Examples demonstrating reconstruction of three-dimensional (3D) scenes from scattered depth measurements obtained from stereo disparity, recovery of 3D shapes from noisy range data, and segmentation of volumetric images for the extraction of generalized cylinders are presented.
