Stereophotogrammetry

Wild Autograph A8, a historical, mechanical-optical device for evaluating stereo aerial pairs (around 1960)

The term stereophotogrammetry encompasses those methods of image measurement in which objects are determined ("reconstructed") in their position and exact shape from two measurement images (recorded from slightly different viewpoints).

The methods are to be understood in the same way as stereoscopy , but are mostly processed on their own, relatively heavy and complex stereo evaluation devices with measuring microscopes . Small hand-held devices such as the pocket stereoscope allow simple evaluations based on free-eyed parallaxes or parallaxes measured with magnifying glasses .
