並列タイトル等Visualization of the Temporal Changes in a Documented Cultural Heritage Based on Photogrammetry and Laser Scanning : Case Study of Barbar Temple
タイトル（掲載誌）国際的な文化遺産の保存・活用に関する総合的研究 = Comprehensive global studies for conservation and utilization of cultural heritage
一般注記As part of the conservation and restoration work undertaken by the Center for the Global Study of Cultural Heritage and Culture (CHC) in Kansai University, the authors have developed systematic solutions to introduce information and communications technology (ICT) for on-site work. This paper explores a technique for visualizing the changes over time of the cultural heritages. In many cases, modern survey records conducted by different teams in different ages have a history at the same cultural heritage site. These survey and/or conservation records are published to be shared in public; however, it is not easy to compare the recorded information and the current conditions. In the same manner, the number of transitions in the history of survey results cannot be precisely united and compared to manage the cultural property over the generations. Survey drawings are typical quantitative data, whereas qualitative information relies on hand-written line drawings and photos obtained from numerous studies conducted on cultural property and archeological surveys. Even though 3-dimensional surveys for recording the details of the shapes of the sites and relics by photometric surveys and/or laser-scanning techniques have become available recently, decades--old past records of monochrome photos are hardly utilized for quantitative or qualitative examination of identical historical objects. This report addresses the abovementioned problem by proposing a method to utilize a photometric technique to integrate newly taken current photos and the old photos from past surveys in identical 3-dimensional space. We demonstrate photo-realistic computer graphics (CG) rendering of the current situation overlaid onto old photos that were taken 60 years ago from the actual archeological site of the Barbar Temple in Bahrain.
