Zusammenfassung:	A method and an arrangement for the automatic control of aerial photography cameras, in which a lens portrays the terrain overflown on a projected area, at least two photodetector rows being disposed on the projected area perpendicularly to the direction of motion of the terrain image and the direction and speed of motion of the terrain image on the projected area, the drift and the vg/hg ratio being determined from the signals of the photodetector. The method eliminating errors in the determination of vg/hg and drift, which are caused by tilts ( omega ) about the aircraft longitudinal and lateral ( psi ) axes. For this purpose the tilt ( omega , psi ) of the aircraft is determined simultaneously with reading the photodetector rows and taken into consideration in the evaluation of the signals of the photodetectors.
