I'm developing an application, that needs to detect FrameMarkers at a distance of about 3-4 meters. Currently I'm using a FrameMarker with the size of a dina4 paper. I can detect this marker up to a distance of about 2 meters.
So the question is, is there a possibility to increase the range of detection, without further increasing the size of the marker? Is it possible to use common id markers and would they increase the detection range? Or can the FrameMarkers be improved in some ways, to be easier to detect?
