Hi Roy,
Let me suggest you some settings that might solve your issues.
-
Select the Linear Rolling Shutter in the Camera Model Edition window:
How-to-correct-for-the-Rolling-Shutter-Effect
-
Select “All Prior” in the Calibration Tab:
- Using GCPs would also improve the quality of your project:
Using-GCPs
How to include GCPs in the project
If you have not include GCPs and cannot fly again I would recommend you this method:
How to obtain the georeference using 2D or 3D GCPs taken from a Web Map Service
An user experienced similar issue here:
Curved-model-tie-points-do-not-calibrate-correctly
If it still does not improve your results, could you provide us the quality report and which drone are you using?
Hope this will help,
Best,
