Wow! You’re putting APP to the test ;-)
If the original Panels are affected by thin plate spline transformations, it would be hard to fix, since then the distortions aren’t scientifically exact anymore. The will deviate unlogically from the rectilinear projection due to the thin plates.
But, there are several options that you can try to get a better results
at 3) Analyse stars,
- set minimum star size to 5-6 and or increase clip star profile to 0.3-0.5, this will help with star lokation precision
- increase the amount of stars limit from 2500 to 5000
- lower the detect above noise kappa value from 8 to 4 (below 3 is unadvisable)
You can enable filter star profile, this could also help in increasing the star lokation precision which could help in getting a better result
I notice some frames have very little overlap right?
When frames have very little overlap, it can help to use triangles instead of quadrilaterals in
4) Register
pattern recognition descriptor shape
That should help in getting those frames that have very little overlap to have better registration.
Let me know if you can improve the result ;-)
