Proposed Instrumentation for Analytical Video Stereoscopy of Extended Images

An approach to real-time photogrammetry is outlined using video techniques in order to combine precision coordinate control of stereo-related images with image enhancement and processing while viewing the stereo model, thereby facilitating photointerpretation in certain applications. One variant replaces the stereo optical paths of an analytical plotter with TV cameras, video signal processing and binocular displays; while a second has video disk inputs of stereo-related imagery.
