Aruco Marker Tracking With Multiple Markers From the Same Dictionary
I'm using ChAruCo marker tracking from OpenCV Contrib. I'd like to track multiple boards, but the mechanism to create the marker boards is not as I would expect.
What I picture is having one dictionary (Say, DICT_4X4_50) to create many markers using distinct ID ranges from the dictionary. CharucoBoard::create() accepts the dictionary and uses markers 0-X to create the board. I'd like to add an offset to the beginning of the range.
If I can create the boards, cv::aruco::detectMarkers() outputs IDs which can determine which board is in view. Is this supported, and if not, how should I go about tracking more than one target?
