三维散乱点云的分割与几何形体重构

Segmentation of 3Dimensional Scattered Points Cloud and Reconstruction of Its Geometrical Model

研究了由三维点云重构几何形体模型的方法与步骤。提出了点云分割的2种交互方法基于特征识别的分割和投影裁剪分割。给出了表面数据点群的边界搜索算法和表面求交算法,实现了一种从三维点云到几何形体的分割与重构方法。

A method and steps of reconstructing geometrical model from threedimensional points cloud are studied.Two interactive methodssegmentation based on feature ideotification and segmentation based on projection and prone are presented for points cloud segmentation.Algorithm of boundary search from surface's points group and surface intersection algorithm are designed. A method segmentation and geometrical model reconstruction from 3D points cloud is studied and realized.
