Paper Abstract

An International Robomation/Intelligence (IRI) DX/VR Vision System and a PC/AT vision system are being used to conduct research on the application of vision systems for performing metric measurements in engineering construction and manufacturing. The IRI DX/VR system is a UNIX-based, multi-user program development workstation with a host computer that is capable of performing about 1 million instructions per second. The PC/AT system employs a Zenith 386 personal computer, two frame grabber boards to permit simultaneous imaging from two cameras, and MS-DOS operating system. Both systems are equipped with 512x512 CCD cameras. An expanding package of software is being developed to perform, on either vision system, many photogrammetric functions, including: camera calibration, image correlation, and feature matching. While the IRI system provides more speed in performing basic image processing operations, the PC system has the major advantage that a large library of commercial software is available for performing data analysis. Geometric distortion characteristics of both line-transfer and frame -transfer CCD cameras are being studied.
