Abstract

Haniwa are clay figures and important archaeological materials because they were made during the Kofun period for rituals and talismans against evil. Archaeologists use their knowledge when they observe visual information such as shapes, sizes, ornaments, and noses of Haniwa for classifying who created Haniwa and where they were created. However, classification by observation is largely based on subjective evaluation, and therefore an objective evaluation method is required. In this study, in order to automatically find facial parts of Haniwa, point clouds are projected onto a plane, and facial parts are extracted from the positions of holes representing eyes and mouths. Automatic extraction of facial parts was achieved by changing the threshold value for investigating the size of holes for each model.
