Digital Cartographic Study and Benchmark.

Abstract

The key problem in the automatic generation of digital terrain data is the matching of conjugate points on a stereo pair of aerial photographs in an accurate and timely manner. This report describes the development of suitable algorithms and systems procedures to perform this matching task in an all-digital environment. Two approaches to automatic image matching were investigated--a strip processing approach and a block processing approach. Of the two approaches, it was found that the block processing approach is more adaptable to the requirements of digital terrain data collection and therefore, it is being investigated further for implementation in an array of fast, microprogrammable processors to provide a benchmark of matching system parameters and performance.
