I'm wondering if it's reasonable to align stereo pairs using a single camera, like a webcam or better a cell phone. To do so, I will take two picture of the same scene, but moving the camera "a bit" to the right for taking the second image. Which set of functions should I use under OpenCV to calibrate my single camera and rectify each pair? Should I use stereoCalibrate with each pair as input, or it won't work cause I wasn't using an ordinary stereo cam?
