Markers >= 4 not recognized

March 29, 2012 - 8:43am #5

I am creating an iOS application based on the FrameMarkers demo application. This works perfectly for markers 0 to 3. However, markers 4 to 511 are not recognized. The program doesn't even get into the loop when I scan one of those markers, so the problem should not be caused by missing marker assignments etc.

// Did we find any trackables this frame?
for(int i = 0; i

Is there any constant, API call or other configuration I have to change to make the program recognize more than the first 4 markers?

Hi rhab,

Take a look at QCARutils.initTracker - you'll find the set of required markers initialised there.

What will be the combination for black and white dots for frame marker 4 for e.g.? Is there any formula that defines how dots will be placed for each marker? Does QCAR detects those black and white dots to see whether it is marker 3 or 4?
