SBM / StereoBM with multiple camera's
TL;DR;
Is it possible to run SBM or anything like it with more than 2 camera's?
Since I have 5 or 6 camera's laying around (all Logitech C270) I was wondering if it was possible to use multiple camera's instead of just 2 of them to create a depth map?
This is typically called 'multi-view stereo'. Try giving that a Google Scholar search. To my knowledge OpenCV has no built-in support for multi-view stereo, so that's on you to develop (and give back?).
