说明：  主动光学三维传感技术中的相位展开算法——二维菱形算法(Active optical sensing technology in three-dimensional phase unwrapping algorithm- Algorithm for two-dimensional diamond)

使用3×1的结构元素，为防止越界，所以不处理最上边和最下边的两列像素(Using 3 × 1 structure elements, in order to prevent cross-border, so I do not deal with the most top and bottom of the two most pixels)

电子海图程序源代码，可以对S57格式文件进行解析，希望高手能将显示做出来(Electronic Chart source code, you can format documents on S57 resolve, I hope you can show up to do)

shape from shaping 3D重构(shape from shaping 3D reconstructed)

实现一个心行图案的各种二维几何变换（包括同比变换，错切变换，平移变换、旋转变换等）(achieve a mind trip of two-dimensional pictorial geometry transformation (including an transform, shear transformation, translation transform, ROTATION))

实现三维对象的平移,旋转变换,以及投影变换,不错的(Realize 3 d object of translation, rotation transformation and projection transformation, good)

说明：  c++的绘制二维等值线源码。有示例数据，可以运行。(c++ two-dimensional contour map of the source。c++ code for contour map)

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.)

一个由matlab编写的从多视点拍摄的图像计算Visual Hull的简单的演示程序，基于空间体积的方法求物体的Visual Hull，对实现由多视点图像求Visual Hull的过程可以起到借鉴作用(Matlab prepared by a multi-viewpoint images of the Visual Hull calculate simple demo program, the method of space-based volume objects for Visual Hull, the realization of multi-viewpoint image for Visual Hull of the process can play a useful reference)
