FROM DIGITAL PHOTOGRAMMETRY TO 3D DIGITALIZATION FOR ART OBJECTS MEASUREMENT O. Feihl*, Archaeologist, Archidata Group E. Renaudin**, Geomatic Engineer, Archidata Group Chemin des Croisettes, 23 - 1066 Epalinges, Switzerland * Info(a'archidata-sa.com ** e.renaudi-n@archeodumim.ch KEYWORDS : Close-range, 3D laser scanning, cultural heritage, digital photogrammetry ABSTRACT: The method presented in this paper try to answer a new question raised by archaeologist and historians: is it possible to compare precisely some cultural heritage object with flexible data acquisition, better accuracy and ease the integration of the computed object? Starting with digital photgrammetry and now thanks to laser scanning techniques, we did develop and validate a solution concept for object virtual reconstruction. Within a European project frame, a digitisation of two gold quiver was realised to establish a comparison procedure for resolving ambiguities around their build process. 1. INTRODUCTION In the context of medieval mountings restorations of Sion’s cathedral and Saint-Maurice Abbey treasures in Switzerland, started at the beginning of year 1990, our group was solicited to draw up the three-dimensional surveys of these objects. Measures were then realized with digital photogrammetry for digital surface model restitution and orthophotos construction. Unfortunately this process was limited by the great infrastructure and time investment for granting results up to help archaeologist in their interpretation task. New way of proceedings were hardly needed. Fig. 1: Geometrical model and orthophoto of the St Maurice “Châsse” acquired by softcopy photogrammetry A solution was found within the framework of a collaboration with the Restoration Research Centre of French Museums. The task placed under the jointly European research project “SCULPTOR”, was to elaborate and evaluate methods for conservation and possible data interpretation of known historical objects. With an aim of helping art historians to determine the manufacturing processes of the three unique gorythes (gold quiver) known in the world. Rostov and Kiev quiver test objects were then digitised to experiment new possibilities. The third one, preserved in Thessalonique, will be measured later on. With the arrival on the market, at the end of the years 1990, of three dimensions laser scanners, restitution and acquisition parameters radically changed; it is now possible to quickly draw up a complete and very precise three-dimensional cartography of art objects and carved architectural elements. The performance and results of three dimensional reconstruction of the quivers, thanks to high resolution laser scanning, are commented in this paper to put in relief the potential offered by such systems. The main purposes is to illustrate the powerful possibilities offered by these new technologies for culture heritage inventory and studies. In this paper we presents on one hand a technique, and on the other hand the possible comparison of two Gorythes with the help of derived 3d digital model, comparison which was not possible before with the available techniques. - 135 -
