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.

Computer-controlled evaluation of aerial stereo images

To permit use of a manual transmission with the advantage of positive drive and hence better fuel economy with a controlled clutch (14), for example under operator control (13) or gear selection control (2013), an engine fuel control positioning stage (11) is provided which receives, upon start of the vehicle and change of the transmission from neutral to first gear, an engine starting speed reference signal from an engine speed controller (19). The clutch, under operator or gear change control, has a disengagement path (15) which causes rapid disengagement of the clutch and a connection or reengagement path (16) which operates with time delay to cause gradual engagement of the clutch so that smooth start-up is insured. A suitable start-up speed is idle speed of the engine, or close thereto.
