Detection of hamming markers for OpenCV written in python.
This package is able to read and create hamming markers, described in this blogpost.
There are two helperscripts located in ar_markers/scripts. generate_marker to generate the markers and livetest. To do the livetest, first generate some markers and print them out. After that, start the livetest and hold the marker into your camera. You will see a blue border around the marker, (if detected) and a green number, showing the ID the marker represents.
