Abstract : A study was made to evolve a density pattern recognition and correlation system that will be capable of scanning stereo aerial photographic information, digitizing this information, and then translating it into elevation profiles. The report presents the techniques employed, which include the scanning system developed, the method of quantizing densities, and recording the pictorial information digitally on magnetic tape. Also presented are some digital pictorial printouts obtained from machine processing of the originally scanned pictorial information. Future work on this program will include further analysis and evolution of a logical scheme for handling density sequences to convert the scanned stereo pair data into elevation profiles; with this information and an x-y plotter, contour lines will be plotted automatically.
