Le levé tachéométrique et son utilisation dans la numérisation de sites archéologiques

Abstract : The three-dimensional record of large architectural structures (several meters to several hundred meters), using 3D scanning is widely used in the industrial and archaeological fields. The used technologies are varied and generate heavy quantity of data with are often difficult to manage. We have investigated a more appropriate method, the statement point by point with a laser total station. Coupled with specialised software, it allows the 3D real-time display of the measured points. This technique is typically used in the statements of architectural facades; specifically, it allows a geo-data and, in general, their use in CAD software. To test this technique, we conducted tests on several archaeological sites. This technique was found to have a number of advantages over the long-range scanners. It can give a real three dimensional plan which can be exploited to make classic statements excavation (2D), but also 3D models in cases where a display or a refund 3D would be necessary. The use of this technique is relatively simple and its implementation is possible under the very variable geographic conditions encountered in an archaeological context. Moreover, the data generated are easily usable for the production 2D or 3D documents. Far from being competitor in the long range 3D scanner, the statement point by point provides an alternative 3D solution, viable, fully applicable in most archaeological context and with a lower cost.
