用于相机参数标定，采用opencv工具编写，用两个摄像头，分别拍摄棋盘格图像，自动计算相机参数-For camera calibration parameters, using opencv tools to prepare, with two cameras, were taken checkerboard image, automatic calculation of camera parameters

由于光学镜头的生产工艺等原因，数码相机拍摄图像常常会出现非线性的几何畸变。针对这一常见问题，采用最小二乘拟合、双线性插值的方法对拍摄图像进行校正。实验结果表明，该方法能够在保证无颜色失真的条件下获得较为理想的校正结果。- the picture is changed when we get it,this mothed is to redraw it

这是一个压缩图片尺寸的工具。可以将数码相机拍摄的照片压缩为300KB以下的小尺寸图片，以便于上传到网络共享空间或者用于其他限制单个文件大小的场合。该工具按比例缩小，不会破坏视觉效果。-This is a compressed image size tool. You can compress digital camera photos to a small size of no more than 300KB, in order to upload it to the network share

usb接口相机拍摄并保存照片，可以设定保存路径及间隔时间-usb interface camera and save the picture, you can set the save path and the time interval
