Abstract : Automatic reseau measurement techniques have been investigated for use with the AS-11B-1 automated analytical stereoplotter and the automated TA3/P comparator. An experimental evaluation with a breadboard system was used to demonstrate the feasibility of automatic reseau measurement and to study and investigate alternate approaches to the measurement task. The investigation involved the use of a flying-spot scanner and electronic correlation techniques. The results of the study and investigation demonstrated that automatic reseau measurement can be performed by correlating an electronically generated reference reseau with the photographic reseau to be measured. The analytical and experimental work resulted in a preliminary design of a basic system. It was recommended that this system be implemented and further evaluated with an AS-11B-1 automated analytical stereoplotter. (Author)
