Image pickup system capable of obtaining a plurality of stereo images with different base height ratios

摘要

In an image pickup system for use in combination with a craft (50) flying over an object zone (51), a plurality of photoelectric transducers are arranged in the craft to pick up partial images of the object zone, respectively, and are divided into forward and backward halves that are operable in cooperation with a signal processing unit (65) to obtain a stereo image of the object zone from the partial images. A selected one of the partial images is picked up from a selected one of the forward half transducers at a time instant and is thereafter picked up again at another time instant with an interval left between the time instants from another one of the backward half transducers that is symmetrical with the selected forward half transducer and spaced apart a predetermined number of photoelectric transducers from the selected forward half transducer. The interal is defined by the predetermined number. The signal processing unit may be located either in the craft or in a ground station.
