摘要

Mural paintings are precious and irreplaceable as cultural heritage components. At present, however, these paintings are subject to increasing various risks of deterioration. Thus, a visual analytics method based on risk management is proposed in this study to analyze these risks. A series of multi-scale analytic tools is designed and developed with multidimensional and multivariate visualization techniques to study single or multiple risks at the scales of sites, caves, walls, and specific risk areas from different perspectives. Several case studies that contain real data are presented and an expert review is conducted to evaluate the proposed method.
