Revision history [back]

First I use opencv-3.2.0-dev and I don't think you use same version. I cannot compiled this line using VS 2015 :

params->doCornerRefinement = false;

I changed it in

params->cornerRefinementMethod = 0;

with this line I found same results. But now If write :

params->cornerRefinementMethod = cv::aruco::CORNER_REFINE_CONTOUR;
