  • Patent number: 6549288
    Abstract: The present invention provides a system for illuminating an object with a special kind of structured light pattern, recording the shape of the reflected points of light by means of a camera, and, by a triangulation technique that does not depend on the fixed direction of the light source relative to the camera, reconstructing the 3D shape of the object through a computer using the data points collected from the reflection of the structured light pattern. The scanning system is portable and does not require data processing contemporaneous with the data collection. The portable system stores in the storage media several images of the objects with different illumination patterns. The data is subsequently processed, by a computer system which applies data processing routines, i.e., the model building algorithms which provide 3D surface generation.

  • Patent number: 6496601
    Abstract: System and method for asynchronous transmission of video images such as from a sending to a receiving terminal or from a sending processor to a storage medium like videotape. The system receives moving picture image information such as analog video digitized into 2D bitmap data and employs a modeling system such as a triangulated mesh modeling system to create an initial image consisting of a compact set of N elements (such as the data points of a triangulated mesh) where the number of elements is less than the number of elements necessary to display the image. In the exemplary embodiment the model elements are bitmap pixel assignments, however other elements such as wavelets, or Fourier component elements, or iterated function system (IFS maps) could also be used.

  • Patent number: 6205243
    Abstract: System and method for rapid collection of data points and construction of a computer model based on a multi-resolution mesh to describe the surface contours and color of an object. The system collects data by projecting shapes of light against the object and collecting (from a position of triangulation relative to the light projector) images of the light as it reflects from the object. The system and method of the present invention are comprised of a multiple laser stripe generation process to project a number of light shapes against the object, the collection of one or more reflected laser stripes in a single image of an images collector to gather sufficient information to reproduce points on the surface of the object. The system compresses the data associated with collected points, which allows for accurate values for the contours of the object to subpixel accuracy.
