Reply to comment by bubudumbdumb in [D] Model for detecting rectangle corners? by hundley10

Thanks for the suggestions. I edited my post to give some examples of the detection that needs to be performed... notice how sometimes corners can be obscured, and the background can make "simple" rectangle detection a poor fit. I will check out ORB though.

The Key here is that by detecting key points you don't need to detect the corners per se : you detect at least a dozen points from the pattern on the card then assuming the card is a rectangle on a plane you can identify the corners.

In other words this can be very robust to occlusions, like you might not see more than half of the card and still be able to identify where the corners are
