inferiority of circular marker for stereo-calibration
Hello, i was evaluating different sets of parameters during the stereo-calibration. It turned out that only 25 calibrations with circular markers were under the top 1000 of about 6720 calibrations ordered by rms. Does this have anything to do with a lack of functions like cornersubpix for circular markers. Because according to some literature i read about photogrammetry, the circular markers should be much better to detect while having a better precision. I hope you can explain this issue to me, and tell me if i am right with my guess.
kind regards
I doubt anyone will explain this, it's almost a research question. Yes circular markers should be better especially if combined with other methods, which unfortunately are not implemented in opencv. See e.g. paper by Datta, Kim, Kanade.
