Offset between two cameras

asked 2019-02-05 17:43:22 -0600

Hi, I'm fairly new to OpenCV so I apologize if this is a simple thing.

My issue is that I have two cameras mounted roughly on top of each other and I'd like to calculate the offset between them. I'm relatively sure that I can do this with some sort of stereo rectify and detection of chessboard patterns, but being unfamiliar with OpenCV I'm not quite sure.

Finding chessboard patterns is easy enough, but using that data for the offset is unclear.

Can someone point me in the right direction?

are the two cameras looking at a fixed object? Maybe you could find the object with both cameras and calculate the bounding box offset...?

You must calibrate your system and you will find offset between your cameras (translation vector T)
