Outline of Final Research Achievements	3D digital technology, which has become popular in recent years, is applied to recording, repair design, production in restoration and restoration, etc. in the restoration of folk cultural properties such as festival stands, and 3D scanners are used to convert 3D data to be repaired, which relies on analog data. We were able to research and develop a series of systems, such as replacing the measured data with CAD data and then cutting out the parts necessary for repair by NC cutting from the three-dimensional data, and applying it to the preservation and restoration of actual cultural properties. In addition, 3D scanning of the twelve hawks (by Chokichi Suzuki) owned by the National Crafts Museum, which has been designated as an important cultural property, will be performed, and the data will be processed appropriately to create a sketchfab (3D data) for the exhibition at the museum. We distributed it to an app that can be viewed on mobile terminals) and cooperated with the exhibition.

Academic Significance and Societal Importance of the Research Achievements	立体的な文化財の保存に関しては、これまでアナログな手法で計測したり2次元的なデータ（図面や写真等）による記録が主な手法であったが、３Dスキャニングの精度が高くなり、それらのデータの加工や閲覧ができるようになった現在、文化財の保存修復において大変に強力な手法になることが、一連の研究の過程で証明された。今回の研究において、対象となった文化財の形は多様であり、実際の現場で応用して得られた結果もさまざまであるが、入力データの処理やアウトプットの方法など一連の技術を含むシステムを作り出せたことで、今後の文化財の保存修復に対して一つの大きな道筋を見出すことができた。
