Angular Rectangle Tracking

[Lightfoot26]

Ok, I have studied the NI white paper and have been running the rectangle track example quite a bit. After getting solid target samples using IR emitters and lenses I have found that when exactly straight in front of the targets I get a beautifully accurate distance from the camera to the center of the rectangle, but as I angle myself to the targets I notice my distances all go horribly awry. Now I KNOW that FRIST and NI, with their never ending knowledge wouldn't make an example that can only be accurate straight on, furthermore I feel like as I read on CD I feel like some of you guys are also successfully reading accurate distances when at an angle comparative to the hoop. Any insight on how I can be successful with angular distance reads of the rectangle?

-Much Appreciated
