摘要
在逆向工程中,常常需要将从各个不同视角测得的点云数据进行多视对齐,统一到同一个坐标系下,并消除两次测量间的重叠部分,以得到被测物体表面的完整数据。针对目前最常用的最近点迭代(ICP)算法,选取两个视图不同位置的数据点集作为控制点集,提出了一种寻找最近点对并建立控制点的名义对应关系的方法。实例表明该方法效果良好。
In order to get integrity of the detected surface data in reverse engineering, it is necessary to locate and merge the different-view-measured cloud data in a global coordinate system. Based on the Interactive Closest Point Algorithm (ICP), a method is presented to find the closest two pints and a nominal correspondence between the controlled point sets selected from the different positions in the overlapped view area. Experiment shows that this approach is effective.
