Simultaneous Image Targets Failed

March 29, 2012 - 1:28am #1

I try to track simultaneous target using vuforia-unity..i add 2 marker on unity, and add 2 different object on each marker, then i change value of "Max Simultaneous Image Targets" to "2", as to this picture below :

then i build & run my application. i try to track those 2 marker, but my object just appear on one of the marker..why is this happen??

Also be sure to use distinct targets. If the targets are very similar the Tracker may confuse them and select only one, even if you've set it up to handle 2.

Okay, try this. Start with the ImageTargets sample and set the Max Simultaneous Image Targets to 2. Run the app and try tracking the stones and chips targets at the same time. If it isn't working, tap the screen and press the "Trigger Autofocus" button while looking at the targets to sharpen the image. You should be able to track these two targets together pretty easily, as they are both high quality. Does that work?

You are trying to track two different markers, correct? You cannot currently track the same marker multiple times.

Try tracking one target and then moving the camera to get the second target in view. You'll need to get most of the second target in the camera before tracking starts. Once you've locked onto both targets it should be easier to maintain tracking on both.
