用于生成相机标定时用的棋盘标定板，修改自网络中他人代码，加入了num_x和num_y两个参数用于控制生成标定板的格数。-Board with camera calibration for generating calibration plate. Modify the code the network in others, joined the num_x and num_y two parameters used to control the number of cells to gener

棋盘格的标定程序，通过拍摄标定板即可实现标定功能-Checkerboard calibration procedures, calibration function can be realized by taking the calibration plate

程序自动生成20幅棋盘格标定板图像，进行角点检测和相机标定-The program automatically generates 20 checkerboard calibration board images and conducts corner detection and camera calibration

用C#开发使用开源二维码源，再加上自己对AUTOCAD的二次开发，生成各类二维码的DWG文件.包括datamatrix 和 qr code棋盘格标定板(Using C# to develop and use the open source two-dimensional code source, together with the secondary development of AUTOCAD, we can generate all kinds of two-dimensional code
