Patent ID: 6977732

Claim:
A miniature three-dimensional contour scanner, comprising: an optical projection module, including a set of optical lens and a digital micromirror device (DMD) chip, by using optical fiber to guide light of an external light source, the light passing through the set of the optical lens to the digital micromirror device chip and being reflected by the digital micromirror device chip, thereby producing structured light patterns, the structured light patterns being projected onto an object by way of the set of optical lens; an image capture module, including the set of optical lens and an image sensing element, the set of optical lens capturing deformed structured fringe images and two-dimensional images from a surface of the object to the image sensing element, which outputs the deformed structured fringe images and the two-dimensional images; and a main control module, connected to the optical projection module and the image capture module for receiving the deformed structured fringe images and the two-dimensional images, adjusting the structured light pattern.
