Outline of Final Research Achievements

The goal of this research is to better understand Jomon residential mobility through the examination of different pithouse types. Prior research has shown a correlation between the amount of materials and energy put into a dwelling its intended use life. Dwelling size affects these costs, but so can building configurations. I made 3D scans of pithouse reconstructions, which were used to create material and energy cost estimates. I developed a reliable method for scanning pithouse reconstructions using photogrammetry. Initial scans were too large to work with, but I created a way to get accurate measures from the high resolution scans. I calculated material costs on a test model and will do the same to the remaining 3D models. I scanned twelve pithouses, created an initial set of pithouse types. The data gathered and the technical challenges overcome in this project created a foundation to continue examining material and energy cost differences between the different pithouse types.

Academic Significance and Societal Importance of the Research Achievements

このプロジェクトは、異なる縄文時代の竪穴住居タイプの材料コスト差を定量化し、それらの変化が何に関連していたかを調査する最初のステップである。このプロジェクトで開発された3Dスキャニングとモデル測定の技術は、他の類似プロジェクトにも適用可能であり、このプロジェクトで作成されたスキャンは測定に役立つだけでなく、将来のデジタル教育プログラムでこれらの構造を仮想的に体験するためにも使用できる。このプロジェクトに関する発表を通じて、日本国内外で縄文文化についての情報をより多く共有することが可能になった。
