Help with calibration and disparity map #1

Open ncrasta opened 3 years ago

ncrasta commented 3 years ago

Hi, I am using two GeT MER 302 cameras (with lens) as a stereo setup. I am following the standard calibration and disparity map generation with OpenCV + python. However, I get wrong calibration parameters and the disparity map is inconsistent (lot of flickering, inconsistency, etc). Have you faced such issues? Thanks.

What is the size of the pattern you use for calibration? I had huge issues when the x an y amount of squares was both even or both uneven, because then rotating the pattern 180° would result in the exact same pattern. This gives a lot of confusion for the calibration algorithm.

so a pattern of 9x7 or 10x8 wouldn't work for me but a pattern of 7x10 did.

I have 9 x 6 pattern with square size of 10cm (its a big board). I have tried a small 9x6 with 2.5cm sq. size as well.
