点云压缩 三维显示 数据输出到文本，并实现数据的输出和保存(point cloud)

ISAR 二维成像（包含运动补偿）数据来源于网上(ISAR two-dimensional imaging (including motion compensation))

可以把jpg图片转换成obj三维网格文件，这样可以在三维形态下观察图像数据(Jpg images can be converted into three-dimensional grid obj file, so that patterns can be observed under the three-dimensional image data)

PLY文件的读取和写入程序：PLY文件是一个三维图形的数据存储格式，包括了三维曲面上所有采样点的坐标，以及所有采样点间的网络拓扑(A program which can read and write a PLY file)

Matlab 三维点云三角化 不是平面域的三角化 是三维点云三角化 亲身测试绝对可用！(Triangle of Point Cloud)

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)

这是一个简单的3D光束图像的显示，用于描绘其射线传播过程(This is a simple 3D beam image used to describe the ray propagation)

Camshitft算法，虽然opencv有Camshift函数，但是用matlab写能更好的了解原理，呵呵！(Camshitft algorithm, opencv Although there Camshift function, but with matlab can write a better understanding of the principle, huh, huh!)

用于求取三维点云数据的法向量，我的人脸建模就是用的这个，效果很好，但必须保证点云没有重叠的，否则会出现严重错误。(Strike a 3D point cloud data for normal vectors, and my face is to use this model, the effect is very good, but must ensure that there is no overlap of the point cloud, there would be a serious mistake.)

meanshift图像跟踪算法，实现目标物体的连续跟踪(meanshift image tracking algorithm to achieve continuous tracking of the target object)
