Application de la photogrammétrie à la documentation de l’art rupestre, des chantiers de fouilles et du bâti

During his archaeological missions the Museum of Prehistoric Anthropology tested the 3D modelling of several typesof objects. His team chose the ‘Structure-from-Motion’ (SfM) method which works according the basic principle of stereoscopicphotogrammetry, namely that 3D structure can be resolved from two or more overlapping, offset images. Most of other methodscapable of surveying, at high resolution, often complex objects and landforms are very expensive and have a difficult portability.Using only a consumer-grade digital camera and a scale on the ground, the user moves through the environment, acquiringphotographs of the area of interest from as many locations and perspectives as possible.…
