Abstract
A three dimensional scan system includes a projection device, an image capturing module and an image formation device. The projection device includes a lighting module for providing a light beam, and a pattern generator for receiving the light beam and project a predetermined pattern. The image capturing module is used to capture images. The image formation device is used to form a projected pattern by projecting the predetermined pattern onto an object, and to project an image of the object and the projected pattern to the image capturing module. An optimal image formation focal plane of the image formation device for forming the predetermined pattern is different from an optimal image capturing focal plane of the image formation device for projecting the projected pattern.
