  • Three-dimensional information processing method and apparatus for obtaining three-dimensional information of object by projecting a plurality of pattern beams onto object
    Patent number: 4867570
    Abstract: Apparatus and method for obtaining three-dimensional information about an object, includes a first optical system, a projection device, a second optical system, and an image sensor. A plurality of pattern beams are radiated onto the object through the first optical system. Optical images formed by the pattern beams on the object are received by the image sensor through the second optical system to detect the positions of the received optical images. The distances from the detected positions of the optical images to a plurality of positions on the object are measured, thereby obtaining three-dimensional information about the object.
