Opencv corner detection Summary

Question about board point matching? Not considered because R and t have no effect on internal reference calibration. Set the upper left corner to the origin. Note: it does not matter what the target is. The internal parameters obtained in the result are measured in pixels. The unit of T is the same as that of the target. Liu Bo is indeed very powerful. After balancing, clever statistics have achieved the ideal threshold, which is quite robust to light !! Image processing is an art.
