Abstract : A sterophotogrammetric instrument for use in topographic analysis by aerial photography is described. The instrument is based on the principle of mechanical intersection, containing on-pedestal-mounted stationary photo-holders and a movable binocular observation system with sighting markers and coordinatograph. To assure constant image sharpness in the presence of angles of inclination in aerial photographs and to simplify construction of the instrument, segment-forming carriages with centers on the surface of the photos are placed between the photographs and the optical system. Holders of the objective lens are connected with the carriages of photo universal joints by levers, the length ratio of which is equal to the bundle transformation coefficient.
