| 研究実績の概要 |
During the past fiscal year I conducted my first trip to scan pithouse reconstructions at the Umenoki site in Yamanashi prefecture. I recorded 3 separate pithouses and created initial 3D models of these structures utilizing over 2500 images. Since the initial recording I have been working on ways to improve the model quality as well as processing the models in a way that makes them easier to work with while still retaining the necessary spatial fidelity needed for material measurements. The photogrammetry process can create highly detailed models, but much of the captured information is not directly related to the main structural components of the pithouse. The main challenge at this point has been to try to isolate the pithouse components that would be directly tied to structural integrity. I have identified and tested a reliable method of creating cross sections of the models in order to more easily measure different structural components without the software being bogged down with unnecessary data.
The initial testing also identified some weaknesses in the capture methods. There were issues with getting certain images to align with the main models. Difficult lighting conditions in the pithouse interiors have caused some problems and some improvements can be made in the creation and utilization of tracking markers inside the structure. I have determined several ways to improve the capture process and will implement them in future scanning trips.
Preliminary research results were presented at the Computer Applications and Quantitative Methods Conference in August.

理由
Covid-19 restrictions caused some travel delays which has put the project behind schedule. While I had intended on having completed multiple scanning trips at this point, due to delays I focused more on model processing and devising ways to improve future capture sessions. Several additional scanning trips are planned for the coming year and the reevaluation of capture techniques as well as the additional work put into model processing methods should speed the analysis of newly captured models.

| 今後の研究の推進方策 |
In the coming year I plan on conducting several more scanning trips. The models will be analyzed and a rough estimation of energy costs associated with different pithouse types will be completed. Research updates will be presented at next year's Computer Applications and Quantitative Methods Conference and a writeup of the project will be submitted to the conference proceedings.

| 次年度使用額が生じた理由 |
Due to Covid-19 restrictions I was unable to make the intended number of photogrammetry scanning trips I had intended. A larger sample size is required to make initial energy costs estimates for different pithouse types. The remainder of the funds will be put towards additional scanning trips allowing me to gather additional data necessary to conduct an architectural energetic analysis of Jomon period pithouse reconstructions.
