The solution to the correspondence problem is important for reconstruction of surface from contours, especially for validity of topology of the reconstructed triangular mesh.

轮廓对应问题的解决是基于轮廓数据曲面重构的关键工作，是保证重建网格模型拓扑关系正确性的基础。

The result after solution of the correspondence, branching and tiling problems is a triangular mesh that is a piecewise planar approximation of a surface consistent with the contours.

解决了这三个问题就可以得到基于轮廓数据的三角网格模型，它是原始轮廓对应的曲面的分片逼近表示。

Second we present the convolution surface and curve correspondence theorem under orthogonal projection, which provide a bridge between 2D image contour and 3D human model.

本文提出了正交投影下卷积曲面和曲线对应的概念和相关定理，为二维的图像轮廓和三维人体模型之间的架起一道桥梁；
