CloudCompare forum

Hi, Daniel,

I want to ask how the coordinate system of point cloud is construct? I thought the value of (x,y,z) of each point is calculated by some way according to the position of the sensor as the initial point (0,0,0), is that right?
If we have 2 point clouds got by two sensors in different places and we know already about the geo infomations of the sensors, how to transform the 2 clouds into a same coordinante system? Can we do that already in CC?

Thanks in advance!

This projection is generally not done in CC, but more generally by the scanner/manufacturer software.

If you know the position AND orientation of the scanner, it is theoretically possible to deduce the 4x4 transformation to apply to each scan (with Edit > Apply transformation) but it will imply some calculus on your side ;)

Thank u so much ! :-)
