能操作佳能单反的OpenCV封装类，经实验可以控制5D mark II拍照并自动包装成OpenCV的对象格式。使得OpenCV的代码能够直接使用5D2来进行图像采集，可以扔掉劣质的USB摄像机了。-Operation Canon SLR the OpenCV wrapper class, the experiment can be controlled 5D Mark II camera and automatically packaged into OpenCV Object Format. OpenCV code can be used directly 5D2 for image acquisition, inferior USB camera can be thrown away.
