METRIC EXPLOITATION OF STILL VIDEO IMAGERY

The development of still video CCD cameras with digital image storage has made feasible the concept of offline, single sensor vision metrolo gy. This paper reports on practical evaluations of such a system for d imensional inspection of aircraft tooling and for structural monitorin g for large scale engineering. A further application of still video te chnology for low altitude aerial mapping is also reported. In each cas e a Kodak DCS200 camera has been employed for the photography in order to rake advantage of the relatively high sensor resolution and adequa te on-board image storage capacity. Aspects of the measurement operati ons, which yielded object space accuracies to 1:80 000 in the industri al measurement projects, are discussed and the results analysed.
