Hello
I am currently trying to calibrate my camera with the asymetric pattern. I created my own pattern similar to the standard pattern. The pattern is detected but the points are not ordered as you can see in the attached img

here is the original image:

I use the standard detector with an adapted blob detector:
SimpleBlobDetector::Params params;
params.maxArea = 1e4;
Ptr<FeatureDetector> blobDetector = new SimpleBlobDetector(params);
grid_visible = cv::findCirclesGrid(img, m_markersize, positions, cv::CALIB_CB_ASYMMETRIC_GRID, blobDetector);
Is this just a bug or is there a some constraint on how the pattern has look like?
