Dear colleagues,
I am doing binocular camera calibration by MATLAB Stereo Camera Calibration Toolbox, however the left image is 640×480 and the right image is 320×288, so the images have to be resized to be equal to run the script. I decided to take the method of zeros padding the right image, but I'm not sure how. Should I have the original image in the center or top left? Or expand evenly to target size? Before I try and compare any methods, I love to hear your opinion and believe they will do great favor to me!
Best Regards,
Ziyu Qi
Problem solved. My preliminary tests show that placing the original image in the upper left corner is the best approach. Other methods will cause the internal parameters of the camera to change, thus introducing unknowable errors for further calibration. Dear colleagues, what do you think of the question with my answer?
I guess that the two cameras not only have different resolutions, but different pixel sizes as well. I would definitely take it into account and resize them to have the same area covered.
