[QUOTE="patmo141, post: 53374, member: 2560"] @Goldrunner I will reserve revealing the cost until a few more guesses are in :-) But you are the closest so far. @doug Nope, not a Kinect and certainly not my son's unless I have some children I don't know about :baby:. The Kinect is pretty much a larger CEREC redcam since it uses a structured light infrared pattern. @scott No gel, just plain ole structured light To scale yes, but zoomed in on my screen Acuracy...too soon to tell but it looks pretty (again, accuracy vs detail) Calibration: I calibrate using a printed pattern on a 90 degree corner with known geometry. My test scans of my "calibration corner" show no visibe distortion, but I'm sure at the edges of the scan where the projector and camera focus breaksdown, there is the potential for aberations. For this scan I spent a great deal of time ensureing that the entire occlusal surface was both in focus for the projector and in focus for the camera BEFORE i calibrated so that my setup was tuned to my subject.
