FROM DIGITAL PHOTOGRAPHY TO A VIRTUAL 3D

Karel Pavelka

Abstract

The rapid development of computer technology and the new technologies of data processing and capturing has brought on the development of automated documentation methods. In modern cultural heritage documentation technology, there are three steps: the documentation of an object, the creation of a 3D model and the visualization of the results. Modern documentation methods like laser scanning or image-based modelling and rendering (IBMR) give us the possibility to create a real 3D model of findings in archaeology, cultural heritage documentation, and the restoration of historical objects. After object modelling, the visualization of results is necessary. Traditionally, it was often made via photo-plans, special maps, vector-plans, isolines-plans, profiles or crosssections. Some years ago, it was not possible to make full use of 3D information to visualize an object for technical reasons. Nowadays, with modern computer technology, there are new possibilities for visualization like rapid prototyping (on 3D printers) or virtual reality. That allows us to fully utilize the 3D information. User-friendly and interesting for the wider public and especially for the younger generation, is the possibility of creating a virtual museum. Our contribution refers to a passage from analogue and digital photographs from a virtual museum and deals with problems with the creation of a 3D model using IBMR technology and the transfer of these models into virtual space.
