Abstract

Method and apparatus for automatically controlling aerial photographic cameras. An exact and reliable control device of low electronic and optical cost, which unburdens the operator, is realized by means of two photoreceiver lines positioned parallel to each other and perpendicular to the flight direction. At least the first line is connected to a data memory, which as well as the second line is connected to a correlator. The correlator is connected, via units for calculating the vg/hg ratio and/or the drift, to setting mechanisms of the aerial camera. A third photoreceiver line can also be provided, coupled subsequently to a data memory. The invention is utilizable in photogrammetry.
