Hi smile i have succesfully built an DSI table or my school project… But There is One Tiny And irritating false blob that is coming from the projector.. I guess it’s because the projector is too bright so that One little light sircle gets shown in CCV… Is There any way to remove that blob with adding another filter? I have 3 photo negatives in my LifeCam Cinema… smile appreciate any answers ^^

You have those Hot Mirrors (IR Filter) for projectors. This may be not the best site but was the fastest I got for now: http://www.reynardcorp.com/products/optical-components/mirrors/dielectric-hybrid-mirrors/88-hot-mirror.html

Hey, I had the same problem and I was able to achieve what you want by changing the camera position and angle in a way that it can’t see the projectors light reflection.. Hope this info helps..
