Abstract :

The use of 3D modeling for heritage documenting has increased significantly in recent years, mainly due to the evolution of more powerful graphic devices available to users with representation tools for the design and computer-assisted manufactures. Computer technology has provided powerful tools of acquisition and representation laser sensors, powerful computers, virtual reality and 3D modeling software, which underwent an evolution of a highly mathematical reality. Researchers are now dedicated to 3D acquisition procedures and especially to data processing. Considered now as the most accurate technique, Lasergrammetry consists to measure objects, by laser scanner, and their restitution in the form of point clouds data files. To process the data, geometric modeling allows relevant 3D models intended to architectural and archaeological representation. This parametric modeling forms a language whose vocabulary would consist of geometric primitives defined from the theoretical analysis of the object. These parameters are translated into algorithms to be implemented into professional 3D modeling software to proceed finally for 3D reconstruction on point clouds. To validate the acquisition-modeling chain, digital tools have been developed and tested on Khmer columns and now being improved on triumphal arches. We aim to present a scientific approach combining Laser scanning and knowledge structuring and that describes the transition from 3D acquisition and data processing to a digital modeling.
