Parallax Measurement Using an Image Matched Filter Correlator

Abstract

A breadboard coherent optical mapping system was tested and used to obtain parallax data in stereo aerial photographs. The system's performance was greatly improved by various modifications and by interfacing it to a minicomputer. Parallax data obtained from the system showed excellent agreement with similar data generated on an operational automatic stereocompilation system. The coherent optical technique offers a number of unique advantages and, in view of the breadboard system's good performance, recommendations for further development of this approach are given.
