中文说明：利用切角距离匹配算法来寻找视频帧与二维图像之间的距离度量图像。这个迭代计算倒角距离，直到找到与帧图像和从三维图像投影的二维图像正确匹配的最佳拟合。
English Description：
Chamfer distance matching algorithm is used to find the distance metric between video frame and 2d image.This chamfer distance is calculated iterated until it finds best fit that correctly matches frame image and 2d which is projected from 3d image.
