Hey all,
I was wondering if I could get a formal definition of the region of interest for stereo rectification. I have my calibration complete and I have minimized the error for calibration. I have highlighted my ROI with a red box. My understanding is that the ROI is the region where there is a corresponding pixel in both the left and the right image. The image below is my rectified and undistorted stereo image. As you can see the ROI highlights a region on the left border and of the right image and the right border of the left image that has no matching corresponding pixels. I was wondering if this is usual. It doesn't really make sense to me that the ROI would include pixels that have no corresponding ones in the other image.
