IMAGE PICKUP SYSTEM CAPABLE OF OBTAINING A PLURALITY OF STEREO IMAGES WITH DIFFERENT BASE HEIGHT RATIOS

摘要

33Abstract of the Disclosure:In an image pickup system for use in combinationwith a craft (50) flying over an object zone (51), aplurality of photoelectric transducers are arranged inthe craft to pick up partial images of the object zone,respectively, and are divided into forward and backwardhalves that are operable in cooperation with a signalprocessing unit (65) to obtain a stereo image of theobject zone from the partial images. A selected one ofthe partial images is picked up from a selected one ofthe forward half transducers at a time instant and isthereafter picked up again at another time instant withan interval left between the time instances from anotherone of the backward half transducers that is symmetricalwith the selected forward half transducer and spacedapart a predetermined number of photoelectrictransducers from the selected forward half transducer.The interval is defined by the predetermined number.The signal processing unit may be located either in thecraft or in a ground station.
