The git in the photo website can download all versions of PLC:https://github.com/PointCloudLibrary/pcl/releases
But domestic downloads often break.
I am using PCL1.8.1 _VS2017_win64 version, now installed record share connection: link: https://pan.baidu.com/s/1gREl9tDmX-sKGMB6sKxfFA extracted code: GXDG
Installation reference photo blog, http://gyshgx868.github.io/2018/03/06/PointCloud/pcl-install/, feel more complicated than the opencv.
