这个程序是用来将三维坐标投影成二维的c++程序。-This program is a three-dimensional coordinate projection into two-dimensional C++ program. . .

此代码基于c++标准库，opencv和pcl点云库，可实现对摄像头调参，调用摄像头视频并读取画面中点的三维坐标获取点云数据-This code is based on c++ standard library, opencv and pcl point cloud library, can achieve the camera tuning, call the camera video and read the middle of the screen coordinates of the th
