Claim 11:
12. A method for generating a three-dimensional reconstruction of an object with reduced distortion, comprising:
using a processor to perform acts of:
receiving, from each of at least three image sensors, a plurality of images of an object illuminated with a moving optical pattern translating along a circular path, from a projector, wherein each image sensor captures the plurality of images of the object from a different perspective, wherein the projector is not synchronized with operation of the at least three image sensors; and
generating, from the received plurality of images, a three-dimensional reconstruction of the object, wherein the three-dimensional reconstruction has reduced distortion due to the received plurality of images of the object illuminated with the moving optical pattern being generated by each of the at least three image sensors from the different perspective.
