Sounds very cool - what computer vision algorithms are you using?
And welcome to the forum. :)

Without seeing the code for your scene --- it could be almost anything.
With that said, if I had to simply guess, I'd say that maybe what you're seeing
is a hard shadow from something, if you have other objects in your scene.
Adding finish {diffuse 0.5} and maybe adding a white sky_sphere to your scene
would help you determine if you're just not reflecting any light from occluded
surfaces.
