| Description | During his archaeological missions the Museum of Prehistoric Anthropology tested the 3D modelling of several types of objects. His team chose the ‘Structure-from-Motion’ (SfM) method which works according the basic principle of stereoscopic photogrammetry, namely that 3D structure can be resolved from two or more overlapping, offset images. Most of other methods capable 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, acquiring photographs of the area of interest from as many locations and perspectives as possible. Software is then used to reconstruct scene geometry. Results from example applications of the technique to engraving art, archaeological zone and architecture are presented. Such data are invaluable for the archaeological heritage inventory on difficult and remote field. To conclude, SfM output is directly compared with that obtained from a classic archaeological documentation. |
