Digital Processing of Dynamic Imagery for Photogrammetric Applications

An experimental, low-cost, portable, digital image-processing system for extending the measurement capability of photogrammetry in certain dynamic image situations is under development. The focus is on image enhancement for heightened visibility of photographs in photogrammetric instruments and towards solutions in real time in situ filmless photogrammetry of dynamic processes. A system consisting of video-rate photoelectronic image capture and digitization, digital spatial filter, correlator/convolver, and displays is described and some qualitative results presented.
