An essential part of a computer vision system is the ability to measure range (distance) to points on the surfaces of three-dimensional objects. This information allows the description of such intrinsic characteristics of objects as orientation, surface condition, and dimensions. A goal of the work described here was the development, testing, and evaluation of a real-time system for measuring range, suitable for the kinds of applications described above. A second goal was the development of algorithms for description of objects, based on their range-image representations. We have shown the feasibility, and measured the performance, of a prototype ranging system that uses a technique called structured light; GWU has also derived and implemented algorithms for rapid description of a limited class of objects using only the data that would be supplied by such a system. Note: Included are a FORTRAN computer program and the following papers: (1) PIPE: A Specialized Computer Architecture for Robot Vision; (2) A New Method for Characterization of Shape; (3) The Quadcode and Its Arithmetic; (4) Adjacency Detection Using Quadcodes. 收起
