3D MODELLING OF THE SVETOVID STATUE FROM ZBRUCZ BASED ON OF INTEGRATED PHOTOGRAMMETRIC AND LASER DATA

The theme of the paper is the preparation of a 3D model of the stone sculpture of Svetovid from Zbrucz, using integrated data, derived from two measurement technologies – close-range photogrammetry and terrestrial laser scanning. The research also focused on comparing the obtained products and the created models, to best represent the measured object. The emphasis was on the quantitative and qualitative analysis of the results obtained. The presented analyses focused on factors affecting the quality of the final product. The research aimed to compare the two methods, evaluate the integration process and develop the best possible 3D model of the statue. The analyses carried out based on the collected data show many advantages of the integration process. The image and laser data have different properties, typical of each measurement method. Photogrammetric data allows better identification of edges and fine details, which is important for sculpture with complex geometry. Laser data, on the other hand, allows the acquisition of accurate spatial information for homogeneous areas and provides direct metric information. A comparison of the similarities and differences in point clouds and models highlights the fact that to create a model of an object, it is necessary to define an adequate data acquisition and processing, depending on the purpose of the model being created.
