hi all,
Because of assembly fault, one of my camera on my stereo rig has its optical axis non-parallel vertically with other camera. My stereo rig is horizontally oriented. AFAIK, rectification process could align frames from these 2 cameras. Is it true ? Is there anything I should be cautious about ? Could I still use it to generate depth map ?
Thanks,
Bit late with my answer, but anyway:
StereoCalibrate calculates the transforms necessary to create horizontally or vertically aligned images. If your horizontal setup has a (slight) vertical misalignment, you get rectified images which do not completely overlap vertically: from one image a bit from the top is cut of, from the other a bit from the bottom.
As long as you have enough overlap for your application, the resulting stereo reconstruction should work fine, only with a reduced working volume.
I am actually working with a ZED camera right now, which has a vertical difference of about 10 pixels of 720, and it works OK when calibrated.
