The project was ordered by the Archeological faculty of the University of Haifa. The essence of the project is applying lidar (on-ground laser scanning) and photogrammetry methods for digital modeling and reconstruction of archeological excavation sites on Israeli territory.
-Such excavations have some peculiarities and the most significant of them is that a great amount of archeological objects (man-made silicon implements, animal bones, bon-fire hearth, etc.) can be discovered at a relatively small area (no more than a few hundred sq.m). Geometrical size the objects which bear scientific meaning may vary from one cm to few tens of cm.
-The technology of the Haifa University assumes not only discovering and getting detailed description of each such object but also a special attention is paid for their mutual spatial positions since it can help to get a number of important scientific conclusions.
For these reasons Drakkar created a special technology which includes extremely detailed (hundreds of points per sc. M) on-ground lidar survey and close-range photogrammetry survey. Such a technology is applied for excavation site survey which is carried out step by step.
Since the number of objects is extremely high, only specialized algorithms of automatic object recognition are applied. Those algorithms also provide contouring, making rendering, profiles and cross-sections.
