• A New Hough Transform for 3D Imaging via Coloured Spots by C. J. Davies, M. S. Nixon and J. N. Carter "Three dimensional (3D) mouth shape extraction is vital to enhance models of speech production, since lip movement is important in speech production and perception. Many techniques have been developed for 3D surface shape sensing[1], but are restricted to static or slowly moving objects. Video-rate triangulation based structured light systems enable 3D surface data acquisition for dynamic scenes. The surface depth information is calculated from a single image of the scene illuminated by a single projected pattern."
  
  
• GRAIL: Graphics and Imaging Laboratory "Welcome to the home page of GRAIL, the Graphics and Imaging Laboratory of the University of Washington's Department of Computer Science and Engineering." Surface Reconstruction : "We are also designing new scanners that will be faster, more automatic, smaller, less expensive, model other visual properties in addition to shape, and produce higher quality and more usable output."
  
  
• Stanford Project to build a 3D fax machine "There is a growing interest in the graphics, vision, and manufacturing communities in building an inexpensive device capable of digitizing the shape and external appearance of objects for transmission, display, and numerically controlled fabrication. Applications for such a device include product design, fast prototyping, reverse engineering, and digitizing of shapes for the visual simulation, animation, and entertainment industries. Toward this end, we are developing a laser-based scanning system capable of generating a seamless, occlusion-free, low-level geometric representation of the externally visible surfaces of an object. The representations we are investigating include fine-grain polygon meshes and 3D voxel arrays with an occupancy function at each voxel. " The Stanford 3D Scanning Repository : "In recent years, the number of range scanners and surface reconstruction algorithms has been growing rapidly. Many researchers, however, do not have access to scanning facilities or dense polygonal models. The purpose of this repository is to make some range data and detailed reconstructions available to the public. Currently, this repository only contains models that were scanned and reconstructed at the Stanford Computer Graphics Laboratory . In the future, we hope to include data sets and reconstructions from other sources."
  
  
• "PRISM stands for "Partnership for Research in Stereo Modeling." It is an interdisciplinary laboratory serving research and graduate level teaching needs at ASU in the area of three-dimensional computer-aided design and rapid prototyping. PRISM provides an umbrella for research in three domains: Data acquisition (via 3D scanning, medical diagnostics, radar, etc.), visualization and modeling, and rapid prototyping." 3D scanning visualization rapid prototyping
