CloudCompare forum

I am doing research using LiDAR to make measurements. What does intensity mean in CloudCompare? Do you mean reflection intensity?

For example, if the LiDAR is mounted at a 30-degree tilt, the point cloud data displayed by CloudCompare will also be displayed at a 30-degree tilt. Is there a tool to correct this tilt to horizontal?

Is it possible to use M3C2 to produce the difference between two point clouds? If so, I would like to know how to do this.
