清华大学本科生课程设计，实现平面点集的三角剖分！用外接圆测试剖分的正确性。算法执行速度较快，但存在狭长三角形！(Tsinghua University undergraduate courses designed to achieve the triangulation of the set of points in the plane! Circumcircle test the correctness of the split. Algorithms perform faster, but there is a long, narrow triangle!)

水平集最新算法，基于局部能量函数，并做了改进(level set new Algorithm, make some improve)

test figure example to check gui

matlab仿真机械四连杆机构运动代码，包括运动仿真和变量变化分析图的生成(matlab simulation code mechanical four-bar linkage motion, including motion simulation and generation of variable change analysis map)

基于势场法的移动机器人避碰系统设计的matlab仿真(Matlab simulation of mobile robot collision avoidance system design based on potential field method)

2012年最新二维码开发(C#)源程序代码，VS2008开发，是C#工具开发二维条码应用最理想的参考范例。提供动态链库接口开发方法，条码图像打印、条码参数设置和非托管API调用方法，并教您如何将文本、图像、声音和指纹压缩放入二维码中。二维条码种类包括：PDF417,Qr_Code,DataMatrix和HanXin等(The 2012 two-dimensional bar code development (C#) source code, VS2008 development, the development of the best examples of reference of the application of the two-dimensional code C# tools. Unmanaged API calls method provides a dynamic link library interface development methodology, and teach you how to compress the image, voice and fingerprint into the two-dimensional code. Types of two-dimensional code including: of PDF417, Qr_Code, DataMatrix and HanXin)

说明：  hough变换提取直线的程度，有详细注解，适合新人。(hough transform to extract linear extent, with detailed notes, for newcomers.)

直接运行TestMyCrust.m, 读取点云txt,或者直接加载mat文件 运行需要几分钟，耐心等待 完成后运行trianglenormal.m, 生成三角面片的法向量 运行完成得到tri.txt（组成三角面片的点的编号信息）,trinormal.txt(每个三角面片法向量数值)，diandian.txt(每个点云信息) 然后将三个数据当做stl_gen.exe的输入文件，得到trisuface.stl文件(run TestMyCrust.m, read point cloud file txt, or load mat file)

关于系统辨识的程序,关于系统辨识的程序关于系统辨识的程序(About the application of system identification, about the system identification program of system identification)

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)
