Hello,
I am using CC and facing a problem with RMS error. After importing the .obj and the GCP points I have performed the alignment. Even after choosing the to be aligned points so close to the GCP points the RMS error is 6.67 after alignment. Can you tell me what is the possible reason behind this and how to fix it?
RMS error too large
Re: RMS error too large
There are multiple reasons, but here are some 'classical' ones:
- how have you imported the GCPs? Do they have large coordinates? If yes, and if you have loaded before using the cloud, have you accepted the suggested global shift?
- have you tried to adjust the scale of the top-be-aligned entity?
- what are the units of the entities (6.67mm is different from 6.67cm ;)
