Dense stereo for sphere image is not implemented.

Alternatively you can see this repo

https://github.com/FengyuGuo/SphereSfm_MVS_converter

This tool will convert the sphere image to perspective image than common colmap MVS pipeline could be runned.

@koby0804 I would add the function to convert sphere images to perspective images.
