3D点云拼接,实现旋转平台点云，ICP配准。点云格式ply，标定好旋转轴后实现拼接然后配准(3D point cloud splicing, rotating platform point cloud, ICP registration. Point cloud format ply, after calibrating the rotating axis, realize registration and registration.)

点云查看器，实现点云数据（.ply格式）的导入和导出、清除当前点云数据、显示每个点的法向、根据每个点法向对应的颜色值，赋予这个点颜色、对当前窗口截屏。(Point cloud viewer, to realize the import and export of point cloud data (.Ply format), to clear the current point cloud data, to display the normal of each point, to give th

在PCL/c++的基础上，循环读取同一文件夹下的ply文件，并且将其转化成pcd格式文件

用最先一层失效理论和渐进失效理论计算层合板失效。(Using the first ply failure theory and progressive failure theory to calculate the failure of laminated plates.)
