Real-world position off by factor of 2...

March 29, 2012 - 12:06pm #1

What I'm doing is tracking a marker on a wall in a room. The room is modeled in 3D in Unity, the model marker and real marker are aligned. When the image marker is detected, the virtual room overlays with the real room. I can then plot my position on an overhead map view of the room.

This works pretty well, except it seems like the distance it puts 'me' at is about twice as far as reality.

I understand this can be because the printed marker is probably twice as small as it should be. It's 8.5x11 and printing it larger is a pain.

Is there a way to adjust this distance in a behavior?

Are you saying that the physical target is half the size of its representation in your model?

What width did you assign this target when defining if for the TMS, and have you maintained that unit scale for the model of your room?
