How to achieve "flat" panorama from a 360 photosphere(?)

[Raymond Blum]

As part of a larger project I have images from a Ricoh Theta that I would like to apply (TensorFlow Lite implemented) Object Detection to and then slice vertically for display.

I've found this HOWTO topic https://community.theta360.guide/t/hugin-howto-convert-360-image-to-cropped-flat-panoramic-image/1271

...but I confess that I've not been able to successfully flatten an image.
Assuming that this HOWTO is applicable,  When I run the batch and produce my output file (.tif by default, not JPEG) the image I end up with is just a crop of the "distorted" or "fisheye" photosphere, whereas I expected/wanted to produce an image normalized so that there was no fisheye effect.

1) Is what I expected feasible?
2) Is this an applicable HOWTO?
3a) If not, is there a more appropriate one?
3b) If so, what am I missing?
Thanks

Hello Raymond,

I assume that you by now have realised that "our" HUGIN is a tool for probabilistic graphical models and not images.

Sorry for the belated reply.
