电子白板用交互通激光检测详细例子，使用了OPENCV库，已通过测试-Whiteboard laser detection interact through a detailed example OPENCV library has been tested

使用C++编写的激光雷达数据的读取和显示代码 用到OpenCV2.4，OpenCV下有很多图像处理的函数，进行激光雷达的处理时也是可以使用的。便于后面进行算法的开发和测试-Use C++ prepared lidar data read and display code uses OpenCV2.4, OpenCV under a lot of image processing functions, laser radar processing may also be used. Behind

通过重心法查找样品上激光点的位置，实现激光定位。(The position of the laser point on the sample is found by the center of gravity method to realize the laser positioning.)
