Study on Distribution of Bayon Faces Worker’s Group Using 3DModels Analysis

Digital 3D models of historic buildings or cultural heritage objects are useful for preservation. Not only can we store them permanently, but the models can supply a clear guideline for the restoration process. 3D models also provide sufficient information about geometrical characteristics that may help archaeologists to inspect and classify the objects. The Bayon temple, which consists of 52 towers, is one of the representative buildings of the Angkor monuments in Cambodia. It is famous for its towers with four faces at the four cardinal points. According to research by Japanese government team for Safeguarding Angkor (JSA), the faces can be classified into three groups, Deva, Devata, and Asura, based on subjective criteria. In this paper, we explore a more objective way to classify the faces by using measured 3D geometrical models by a laser range sensor. Keyword Cultural heritage, Digital archive, 3D models
