项目摘要

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.

在过去的一个财政年度里，我进行了我的第一次旅行，扫描在山梨县的梅之木遗址的pithouse重建。我记录了3个独立的木坑，并利用超过2500张图像创建了这些结构的初始3D模型。自从最初的记录以来，我一直在努力提高模型质量，并以一种更容易使用的方式处理模型，同时仍然保留材料测量所需的必要空间保真度。摄影测量过程可以创建非常详细的模型，但捕获的大部分信息并不直接与木髓的主要结构部件相关。在这一点上，主要的挑战是试图隔离将直接关系到结构完整性的支柱组件。我已经确定并测试了一种可靠的方法来创建模型的横截面，以便更容易地测量不同的结构组件，而不会使软件陷入不必要的数据中。初步测试还发现了捕获方法中的一些弱点。在让某些图像与主要模型对齐方面存在问题。在木墩内部困难的照明条件已经造成了一些问题，可以在结构内部的跟踪标记的创建和利用方面进行一些改进。我已经确定了几种改进捕获过程的方法，并将在未来的扫描旅行中实施这些方法。初步研究结果已在8月的计算机应用和定量方法会议上发表。
