LEAST-SQUARES METHOD-BASED
FEATURE FITTING AND EXTRACTION
IN REVERSE ENGINEERING*
Abstract: The main purpose of reverse engineering is to convert discrete data points into piecewise smooth, continuous surface models. Before carrying out model reconstruction it is significant to extract geometric features because the quality of modeling greatly depends on the representation of features. Some fitting techniques of natural quadric surfaces with least-squares method are described. And these techniques can be directly used to extract quadric surfaces features during the process of segmentation for point cloud.
