Track image or symbol inside of frame marker?

September 11, 2013 - 4:29am #4

Hi everybody,

 

I plan to make an AR-Boardgame where the players have to place tiles into a sheet with holes for the tiles.

I have to know the position as well as the kind and orientation of each tile.

 

The approach i would like to follow is:

  • printing a frame marker around each hole to identify the position in the boardgame-coordinate-system
  • printing an image on each tile to identify it
  • then track the frame marker for the position
  • If the tile at this place is still unknown, track the area only inside of the frame marker to identify the tile

 

Is this possible with vuforia?

I think I would need to take a picture from the camera frame and mask everything exept the inner part of the tile. Then I would need to track the symbol inside of that image.

But I am not sure, if i can use a generated image rather than using the camera input with vuforia.

Why don't you try it and see by building a small prototype - then you can post your results back here :)

Hi Nalin,

Thanks for your reply :)

 

Currently I am involved in another project and have a huge amount of work to do for it.

That's why I didn't dived into vuforia much so far.

 

I hoped anybody here would have enough experience to tell me, if my approach is going in the right direction...

However, I will prototype this as soon as I have more time for it :)

What you're describing should be do-able. ImageTargets and FrameMarkers are distinct target types, but can still be used together and will both provide transform information to identify their position and rotation. Also you can use colliders to recognize when targets are touching or overlapping in Unity.
