Paper Abstract

Developers of videometric systems must attend to the problems of image storage, retrieval and, for multi-station triangulation, the unambiguous correlation of images with appropriate epochs. For dynamic testing with multiple cameras, this problem is manifest. An `off-the- shelf' component two camera system was recently developed for measuring the six degree-of- freedom time histories of a free flight wind tunnel model. Vertical interval time codes (VITC) were used to correlate fields from each camera station which had been stored onto video cassette recorders (VCR). Subsequent use and development has emphasized the practicality of this approach. This paper discusses the image management technique used along with some details of the particular wind tunnel application. The utility of post-test processing of long sequences of VITC encoded imagery stored to VCR is established.
