<p>An apparatus for use photogrammetry and having two spaced-apart parallel scanning zones (15) to which the photographs of a stereoscopic pair of photographs are mounted.</p><p>An optical scanning system (35, 36, 37 or 35, 36, 71, 73, 75) which is mounted to a carriage (25) is provided for scanning the two scanning zones (15) and for projecting images of the respective zones to a binocular viewing system (12), and a secondary optical system (42, 44, 45, 46, 49, 50 or 63, 64, 65 or 83, 84, 73) is provided, preferably on the carriage (25), for superimposing reference marks (41 or 62 or 82) on the projected images.</p><p>The scanning system is arranged whereby simultaneous scanning of the two scanning zones (15) can be effected in a first (y) direction parallel to the scanning zones, and whereby independent scanning of the two scanning zones can be effected in a second (XR, xL) direction which is parallel to the scanning zones and orthogonal to the first direction. Also, means (43 or 55 or 72) are provided to permit relative (8y) scanning of the two scanning zones in the first direction or for optically moving the reference marks relative to one another in the first direction so as effectively to provide a (δy) shift.</p> |
