you usually need 6 input images, one in each direction (like a box). do you have those ?

it's still unclear, what you're doing, and where the problem exactly is.

please edit your question, add your input and code, move your image from dropbox to here, etc.

(also, i don't think, that stitching can be used here (no overlap))

sorry, but still unclear. do you want to "straighten out" the 2nd image (make it rectangular) ?

do you want to produce the 1st image (from several shots) ? and how would this be related to stitching ?
