Hello everyone,

I am trying to stitch  panoramas taken with a Panono camera on a tripod. In the past, I uploaded the extracted JPG files (not the UPF files) to the official Panono website, and the stitching was fully automated and worked perfectly. Unfortunately, the service no longer exists.

For each panorama I have:

  • 108 JPG images extracted from the UPF file

  • The original UPF file

  • Previously generated final panoramas for reference

The important point is:
The images fit together perfectly. The camera geometry is fixed (36 lenses in a rigid sphere), so the relative positions never change.

In PTGui, using standard settings (Phone / Tablet, normal lens), the alignment already looks surprisingly good. The overall geometry seems correct.

However, the panorama still contains holes because PTGui does not properly recognize and connect all overlapping image pairs.

I could manually add control points and fix the missing connections, but with 108 images per panorama this would take an enormous amount of time.

So my actual question is:

Has anyone here successfully stitched Panono JPG exports in PTGui?
Or does anyone have an idea how to approach this more efficiently (e.g. fixed rig setup, specific lens model, parameter locking, grouping strategy, etc.)?

Any experience or ideas would be greatly appreciated.

Thank you very much!

Hello everyone,

I am trying to stitch panoramas taken with a Panono camera on a tripod. In the past, I uploaded the extracted JPG files (not the UPF files) to the official Panono website, and the stitching was fully automated and worked flawlessly. Unfortunately, the service no longer exists.

For each panorama I have:

  • 108 JPG images extracted from the UPF file

  • The original UPF file

  • Previously generated final panoramas for reference

Important clarification:

The images actually match perfectly. The camera geometry is fixed (36 lenses in a rigid sphere), and the relative positions between the images never change.

The real problem is not misalignment.

The problem is that PTGui does not correctly recognize how the images belong together.

When I use default settings (Phone / Tablet, normal lens), the alignment is already surprisingly good. The geometry looks mostly correct.

However:

  • Some images are apparently not connected correctly in the control point graph.

  • The optimizer leaves gaps.

  • The final panorama contains holes, even though the source images definitely overlap perfectly.

So the issue seems to be that PTGui fails to automatically detect and connect all matching image pairs correctly — not that the geometry is wrong. 

Of course, I could manually add control points and connect the missing images by hand. But with 108 images per panorama, this becomes extremely time-consuming and impractical for multiple projects. 

So my actual question is:

Has anyone here successfully stitched Panono JPG exports in PTGui?
Or does anyone have an idea how to approach this more efficiently (e.g. fixed rig setup, specific lens model, parameter locking, grouping strategy, etc.)?

If anyone has experience with stitching Panono data in PTGui, I would greatly appreciate your guidance.

Thank you very much.

Hi Amelie,

I found an old project file for a Panono image set, see attached.

Load your images, then do File - Apply Template and then Align Images.

Keep in mind that the panono due to its size suffers from severe
parallax, you will likely see many small stitching errors. There's not
much that can be done about that.

Kind regards,
