2 track irs for 3d tracking

Post by jetmech »

i was woundering if it would be possible to take two track irs put them side by side to get 3d tracking. my guess would be that it would only take some programing in the software, and "maby" a base so the software knows how far apart the two track irs are apart. with this it should be able to triangulate the position making it able to track the forward and aft movement of your head.

Hello:

Yes, you can create a 3D tracking system if you have 2 units and put them side by side. We will be launching a SDK that will allow our users to do this in a while.

Interesting.. do they still track one ordinary dot ?

What about using a single unit to track two IR reflectors?

I've been emailing them about the possiblity of using one TrackIR for 3D.

3D tracking on single hat with one TrackIR might be possible with 3 different active color LEDs arranged in a known shape. I use tracking software all the time for animation, and I do it without software sometimes to place a camera in a scene. It's interesting how there can be so many "solutions" to a problem. One of them just has to be passable. I'm sure you could get some 3D tracking information from a single TrackIR. What the resolution would be I don't know. Seems the FOV is pretty much filled to track a single dot. One of your LED's would pass out of view so you'd have to have software capable of dealing with that. More than three distinct known position dots would help the track enormously. The software would also steal more CPU to do a 3D track. 2 TrackingIR's could more easily do it but you'd still but much better off with a very special 3D track hat that had a special pattern of known size and position so both could position it in 3D from their perspective. It would be interesting if the Track ir had wider FOV for 3D tracking. This would allow for more 3D movement at the expense of Resolution which at this time is really awesome. .75 FOV .75 resolution, worth it?
