Paper Abstract

Photogrammetry consists in taking a photo from the same part of the ground with the same camera but from two different places and then use this pair of pictures for stereoplotting Stereoplotting consists in placing the stereopair of photos into the two projectors of an optical and mechanical stereoplotter with the same interior orientation as the camera used Interior orientation of the camera is measured by calibration. Then relative and absolute orientation of two projectors are done. This mean orientate the two projectors into the same relative and absolute position angles as were the camera during the shot. This is done taking at least three control points for hight and two control points in X and Y to match will the map manuscript plane. Nowaydays optico-mechanical plotters which have some limitations and are very long and difficult to operate are being replaced by analytical equipment which give : - better accuracy due to - simplier construction - digital corrections of parameters such as earth curvature, films deformation, atmospheric refraction lens distorsion. - faster operation typically 15' for model orientation instead of one or one and half hour. - larger field of application, no limitation of : - focal lens of camera, - convergence.
