Abstract

The invention is directed to an apparatus for evaluating aerial stereo images. The apparatus includes an analytical plotter which is supplemented with an ancillary device for photoelectrically scanning and digitalizing subregions of both stereo images. The signals of the device are computer-correlated with each other to automatically, for example, determine the coordinates of homologous points and the occurring parallaxes. A method of carrying out the invention is also disclosed.
