  • Method for producing image with depth by using 2D images
    Patent number: 8180145
    Abstract: A method for producing an image with depth by using 2D image includes obtaining a set of internal parameters of a camera. The camera takes at least a first and a second 2D images with a small shift. The first 2D image has N depths, and N?2. Several sets of external parameters of the camera corresponding to the 2D images are estimated. A 3D information respectively corresponding to the N depths of the first 2D image at each pixel or block is calculated. A proper depth of each pixel or image block is determined. Through the internal parameters, the external parameters, and the N depths, each pixel or image block of the first 2D image is projected onto N positions of the second 2D image, so as to perform a matching comparison analysis with the second 2D image, thereby determining the proper depth from the N depths.

  • 3D object fabrication methods and systems
    Patent number: 8155774
    Abstract: A 3D object fabrication method implemented in a fabrication system includes the following steps. A digital object model is retrieved. Sections of the digital object model are respectively printed on plural pieces of plane material. The pieces of plane material are combined to form a physical 3D object of the digital object model.
