Hi,
This is an interesting thread. I am modelling a wall with laser scans that are registered perfectly, GCPs extracted from the pointclouds and then photographs taken with a Fujifilm X-T3/27mm lens.
Despite importing the laser scans as exact/georeferenced AND fixing the prior pose as Locked, the images and scans were deviating wildly depending on various settings. By deviation, I mean to the order of tens of metres over the length of the wall.
It was only when I started experimenting with distortion models that things started to make more sense. I found that K + Brown3 with tangential 2 gave the only good result.
As a side note, RC reports that my camera is not in the database, so part of me wonders whether this is part of the issue?
Does anyone else have a comment on the choice of distortion model for hybrid photogrammetry>
