说明：  三维重建是指对三维物体建立适合计算机表示和处理的数学模型,是在计算机环境下对其进行处理、操作和分析其性质的基础,也是在计算机中建立表达客观世界的虚拟现实的关键技术。(Three-dimensional reconstruction refers to the establishment of a mathematical model suitable for computer representation and processing of three-dimensional objects. It is the basis for processing, manipulating and analyzing their properties in the computer environment. It is also the key technology for establishing a virtual reality to express the objective world in the computer.)

图像角点提取－harris，以及非最大抑制等，并有其他角点检测代码(Image Corner Detection-harris, as well as non-maximal inhibition, and has other corner detection code)

Nurbs曲线曲面源代码。其中包含德布尔算法计算B样条曲线，德布尔算法计算B样条曲线的导矢，B样条曲面，Nurbs曲线，Nurbs曲面。(The program code for NURBS curve and NURBS surface.)

说明：  对二维数据进行变分模态分解，可用于地震数据去噪等(Variational mode decomposition of two-dimensional data can be used for seismic data denoising, etc.)

说明：  fdtd 时域有限差分法pml吸收边界条件 实现(fdtd FDTD method achieved pml absorbing boundary condition)

说明：  MATLAB三维曲线拟合，说明各种情况，分析时可以参考(MATLAB 3D magic fit)

matlab求解雷诺方程，里面的程序需要适当修改(matlab solving the Reynolds equation, which the program needs to be amended as appropriate)

说明：  提取图像中的显著对象部分，就是人视觉感知的主要部分，运行的是demo.m(Extraction of the image part of a significant object is the main part of the human visual perception, running demo.m)

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)

基于二维照片的体素法三维重建程序，重建之前进行误差分析，效果还可以。(Voxel-based method two-dimensional picture reconstruction process, before reconstruction error analysis, the effect can be.)
