Align by Picking give a strange result
Posted: Fri Oct 16, 2020 11:15 am
Hello group.
I'm trying to align (or better "register") a Scan using the command align by picking.
So, I'm putting three spheres and their correct coordinates (in SR WGS84-UTM 33N). I want to fix the rotation only on the Z axis to preserve the verticality and leave free the traslation on each axis.
Well how you can see, the roto-traslation seem work correctly but reamain the "SAME" error on the Z around 42 mc.
My question is ... WHY?
Why algoritm don't traslate on Z axis the model by 42 cm?
I'm doing something wrong?
