实现了点云的三维网格化重建，并附上了些测试点云数据(Realized three-dimensional grid point cloud reconstruction, along with some test point cloud data)

shepp-logan的2D直接傅里叶反变换法(Shepp-logan 2-D Direct Fourier Inverse Transform Method)

说明：  基于图像序列的单目三维重建，运用运动恢复结构，SIFT算法等(Monocular 3D reconstruction based on image sequence, using motion recovery structure, SIFT algorithm, etc.)

迭代最邻近点算法进行3D点云的匹配，四元数方法求旋转(ICP algorithm for point clouds)

该函数能完成多视图的三维重建工作，牵涉很多三维重建工作的函数，相信一定会对你有用(The file includes 3d reconstruction code)

Delaunay三角网的逐点插入法. 原始作者 @author Paul Chew * * Created July 2005. Derived from an earlier, messier version.(Delaunay triangulation point by point insertion method. Original author @ author Paul Chew** Created July 2005. Derived from an earlier, messier version.)

在P4P问题中,当空间4个点共面时,不仅摄像机坐标系与物体坐标系之间 的旋转矩阵R和平移向量t可以线性求解,而且可以同时确定摄像机的有效焦距f和像素比例，该程序设计模拟已知相机矩阵M情况下由已知三维空间点和图像坐标情况求解相机外参数矩阵(When space four points coplanar P4P problem, not only between the camera coordinate system and the object coordinate system rotation matrix R and translation vector t Can be solved linearly, and can determine the camera s effective focal length f and pixel ratio, the program is designed to simulate a known camera matrix M Camera outside the parameters matrix case solved by the known three-dimensional space points and image coordinates)
