Abstract: A system for simultaneous real-time three-dimensional geometry and color texture acquisition. The system includes a system processor for generating at least three phase shifted black and white fringe patterns with a phase shift of 2 ?/3, a light projector adapted to project the fringe patterns onto an object, the projector being electrically connected with the system processor, and a color camera for capturing the fringe patterns to generate at least three raw fringe images. The fringe images are used to calculate a black and white texture image which is further converted to a color image by employing a demosaicing algorithm. The fringe images are also used to calculate a wrapped phase map that is further processed to generate a continuous unwrapped phase map by employing a phase unwrapping algorithm and the unwrapped phase map is converted to co-ordinates using calibrated system parameters for point-by-point three-dimensional shape measurement.

Abstract: In one aspect, in general, parallel image and depth maps are acquired of a subject using a three-dimensional camera on a common and dense set of pixel locations. A two-dimensional mesh animation is determined based on motion tracking in the acquired images. The two-dimensional mesh animation is then combined with the depth maps for form three-dimensional mesh animation suitable for rendering.
