Description

Describe the feature

I've tested Photo-Sphere-Viewer with an Insta360 X5 image with INSP extension which is basically a JPEG with extensive EXIF data. It has dual fisheye images so I used the corresponding adapter. It displays ok, however the stitching is clearly shifted where both cameras meet. I think that perhaps this format has the stitching parameters already embedded as EXIF tags. One candidate might be the parameters tag:

Parameters : 2 2655.019 2693.880 2675.210 0.188 -0.029 90.085 2650.017 8072.510 2685.970 -0.326 -0.038 88.740 10752 5376 1137

You can download the test file from here: https://seewald.at/files/184455_foto.insp

If you need anything else, let me know.

Best, Alex
