| 摘 要： | 主要讨论了基于序列图像的三维重建中的两个关键算法:特征数据点列的重采样算法与三角化算法.本文改进了Chetverikov等提出的轮廓曲线中高曲率点的检测算法,使在重采样时,数据的压缩比得到了明显的改善,也显著地提高了可视化速度.并使用一种简单的三角化算法,对重采样后的数据点列进行三角化,实现目标的三维重建.

| Abstract: | Two important algorithm in 3D reconstruction of image sequences are studied,i.e.re-sampling algorithm and triangulation algorithm.An improved algorithm for detection of high curvature points in planar curves is presented.This algorithm can improve the performance of re-sampling and 3D data field visualization.Triangulation is implemented by using a simple triangulation algorithm.Sequentially,3D object reconstruction was achieved. |
