Stitching disarray

Hello,

I have made the jump from hardware stitching in a Ricoh Theta to software stitching in Autopano Giga using images from a GoPro Omni. Most of my images stitch properly. All I need to do is adjust the center, straighten, etc. But a few rendered 360s show notable problems in the stitching. If you look at the attached file of a small chapel, you will see that the top of the confessional partition (to the right of the center point) is poorly stitched. The door is also not stitched properly.

I have tried introducing manual control points, but when I do so the render is no better, and the software reports poorer stitching quality than it had before (going from a green to yellow flag). I attach a screen snapshot of my attempts to add manual points (#67-70) to correct the problem with the stitching of the confessional partition.

Does anyone have any advice?

Hello,

You can't avoid parallax issues using that kind of RIG, especially on close objects. In your case, you also have homogeneous areas with a lack of details.
Have you tried to increase detection quality, add manual control points (pixel accuracy). Have you also tried to use Omni importer then export to Autopano ?

Kind regards,
Olivier

Thanks, Olivier, for your response. I am using the Omni importer, yes. I did try manual control points, but they didn't help. I'll try to increase detection quality too. But at this point I wonder if my best option isn't to either reshoot with the dual-fisheye Ricoh, or try to fix it in Photoshop.
