I set up a stereo cameras, one for color image and another for UV image. Due to the difficultiness to find lenses with same intrinsic parameters for both cameras.
I used stereo camera calibration app and rectified both images. But checkerboard didn't totally match. It seems vertical grid was almost matched but horizontal grid was
not matched(left image). For the next step, I translated UV image(magenta) using translation parameter obtained from the stereo calibration. It's been partially successful(right image).
Here're my questions.
1) How does rectify fuction works? why does it seems to match images' vertial grid?
2) Is it correct procedure to rectify images; stereo calibration -> rectify both images -> translate?
3) When I use 'imtranslate' function, how can I estmate the pixel translation? Looking up reprojectedpoints data does't seem to be easy and clear way.
Thank you for your answer in advance.
