全体件表面数字化多视拼合的系统方法

摘要

给出了解决三坐标测量中多视数据拼合的系统方法。首先通过坐标转化将多视数据统一化，然后将空间的数据点投影至平面上形成单视数据点的三角拓扑关系，使散乱的数据点具有面信息。利用射线交点记数法将重叠处的点从另一视的数据集中分离出来，提出了将多值数据点自适应滤除的新方法，最后基于外接圆规则重新三角化。%This paper presents a new system method for multiview data merging of wrap around object. First, multiple sets of scan data can be unified by coordinate transfer. Then using a feasible triangulation method to build up the topology of one set of scan data. After cutting another data set into two parts, one part of which lies outside the first data set and another one lies inside it, we propose a new method to judge what points are real ones which we should merge them into the first data set. Using this new method we can distinguish multi-value points and error points. Finally, A re-triangulation method based on circle rule is used to merge points into the triangular plane.
