Tracking FrameMarkers from long distence

April 11, 2012 - 5:29am #1

Hi,

I need to track Frame markers over long distance nearly 4 meters. Using a4 size printed marker I tried But nearly after 2.5 or 3 meters tracking performance was not so good even with angler view tracking was not so good. What I need to do in this case.

Hi omkarois,

The rough gauge we go on is you should be able to detect a well defined and high quality Image Target that covers about 100 pixels of the camera image - that's where the target is face-on to the camera.

For Frame Markers the size is about 50 camera pixels.

If the target is normally not face-on to the camera then the target will need to be bigger/closer.
