As README says, cylinder mode expects:

You are only turning left (or right) when taking the images (as is usually done), no translations or other type of rotations allowed. Images are taken with the same camera, with a known FOCAL_LENGTH set in config. Images are given in the left-to-right order. (I might fix this in the future)

So the failure is expected
