Batch Builder Stitching Errors

[Barbara Aptseshko]

Greetings!

Please advise on the following question.

I have been working with PtGUI for quite some time now, and my task is to stitch a large number of panoramas - from 5 to 500. In my work, I use photos from various cameras—insta360, ricoh, DSLR with Fish-eye. To automate the panorama stitching process, I use the Batch Builder function.

I follow your official guide: I create a template based on one of the panoramas, then add it to batch processing. After starting the alignment, errors almost always occur, due to which the stitching process either does not complete, or the result has critical or non-critical defects. This forces me to stitch panoramas manually, which takes a lot of time. These errors mainly occur with insta360 and ricoh. Typical errors I encounter include:

The horizon is tilted.

Exposure alignment errors.

Minor errors at lens joints.
Example of such Photos below. It was insta360 x4. Batch Builder with the template. Half of the photos stitched correctly, half like that.

Please advise:

What could be the causes of these problems during batch processing?

Are there any solutions? Perhaps I am missing some settings or there are some non-obvious steps for using Batch Builder more successfully with a large number of images?

Thank you in advance for your help.

Barbara, Probably your template is doing too much unnecessary processing.  Visit the Project settings tab and turn off the option to do Align Images.  Just do Create panorama under Batch Stitcher Actions.   That could be enough, but possibly you might need to enable Align Images but turn off all options except Perform automatic exposure and colour adjustment.  Ideally, you would create a template using two shots taken with the camera panned around through 90 degrees between them, preferably in a location where things are generally far away to avoid the effects of parallax.

Hi Barbara,

For one shot cameras such as the Insta360 please see 6.41:
https://ptgui.com/support.html#6_41

Keep in mind that the X4 doesn't provide accelerometer information in
its metadata. If the camera is tilted, PTGui cannot automatically level
the image.

Because the two lenses are fixed to each other you can get reasonable
stitching without having PTGui align the images for each panorama. There
is a small parallax, so nearby objects may suffer from small stitching
errors.

For regular panoramas taken with a DSLR: there will be cases where PTGui
cannot find control points, for example if an image contains just a
white wall or blue sky. Batch processing such panoramas will not be
succesful, unless you provide a template. The template should have the
images roughly aligned, PTGui will then keep that alignment for images
lacking control points.

If you need specific help, please make a set of images available and the
template you are using.

Kind regards,
