Hello, I’m using a 4K camera and would like to detect fairly small ARUCo tags on the image. But it seems there is a hard threshold relative to the size of the image. I’ve tried modifying the parameters, such as the minimum rates, but the smaller tags are still not detected.
I’m wondering which parameter I should change to get these tags to be detected.
See the example image : I can’t detect the smaller Aruco tags at the back.
PS : I’m using OpenCV 4.8.0, compiled from source, and I adjusted my adaptive theshold constant to 20 as it helps with detecting the bigger tags more reliably.
