I have a point cloud and would like to move this to the local coordinate system for example from Revit facing toward the first quadrant. We have a file with 3 ground reference points and on-site marked with blocks. So it is possible for us to get the coordinates from the point cloud so, we have:
- 3 ground reference points in RDNew
- 3 reference points in the point cloud from the 3 blocks
- an Origin point for the absolute 0,0,0 coordinates
We want to move the point cloud to the local coordinate system and rotate towards the first quadrant.
How can I perform this transformation with for example a proj4 string?
