AUTOMATED 3-D MEASUREMENT USING MULTIPLE CCD CAMERA VIEWS

The goal of automated 3-D measurement of arbitrary objects using photogrammetric methods is a long way from being achieved, but significant progress is being made. However, automated measurement of small objects using inexpensive CCD cameras and frame grabbers is becoming increasingly common. A number of such systems have been developed both for commercial use and for academic research. It is within this latter context that a system to measure objects within a controlled environment has been developed at City University. The objective of the research is not only to produce a flexible measuring system for use in on-line inspection but also to address many of the fundamental problems that hinder 3-D measurement outside a controlled environment.
