ACQUISITION OF THREE-DIMENSIONAL IMAGES BY AN ACTIVE STEREO TECHNIQUE USING LOCALLY UNIQUE PATTERNS

摘要

A system and method for acquiring three-dimensional (3-D) images of a scene. The system includes a projection device (P1)for projecting a locally unique pattern (LUP) onto a scene, and sensors (C1, C2, C3) for imaging the scene containing the LUP at two or more viewpoints. A computing device matches corresponding pixels in the images by using the local uniqueness of the pattern to produce a disparity map. A range map can then be generated by triangulating points in the imaged scene.
