The use of Augmented Reality as a reconstruction tool in Building Archaeology. Developing interdisciplinary methods with Mixed Realities at the Roman world heritage sites of Trier.

在建筑考古学中，丢失建筑条件的三维重建模型被理解为启发式工具。它们是某些视觉创意的媒介，对澄清室内设计或建设性流程等问题直至详细的解决方案做出了决定性的贡献。这些模型在内容上的意义和价值与真实对象密切相关，但实际的建模过程与现实对象脱节。借助增强现实(AR)的技术可能性，准确地说，这个创建重建模型的过程首次直接与本项目中的研究对象联系在一起，从而重新定义了重建方法。只有增强现实的沉浸式效果，即真实环境和虚拟内容的叠加，才有可能在三个现实水平上直接对对象进行重建。因此，实际存在的建筑库存(第一层)与数字捕获的建筑库存(第二层)相链接，以便直接在对象(第三层)上建立虚拟重建。首次使用AR智能眼镜直接在要检查的建筑位置进行实际建模工作。这一创新办法的一个组成部分是将参与重建进程的所有人员联系起来。广泛、跨学科和跨学科的讨论扩大了学科专业知识；这种协作工作的结果将直接落实到重建工作中。该项目的目的是开发一种工作工具，以便有条不紊地应用这一新方法。该工具的测试和开发是在该项目的框架内进行的，以特里尔的巴巴拉皇家浴池为例。

In building archaeology, three-dimensional reconstruction models of lost building conditions are understood as heuristic tools. They are the media of certain visual ideas and contribute decisively to clarifying questions about e.g. interior design or constructive processes up to detailed solutions. The significance and value of these models in terms of content is closely related to the real object, but the actual modelling process is detached from it.With the help of the technical possibilities of Augmented Reality (AR), precisely this process of creating a reconstruction model is for the first time directly linked to the investigated object in this project and the reconstruction methodology is thus redefined. The immersive effect of augmented reality only, i.e. the superposition of real environment and virtual content, makes it possible to work on the reconstruction directly on the object in three levels of reality. Thus, the actually existing building stock (first level) is linked with the digitally captured building stock (second level) in order to build up the virtual reconstruction directly on the object (third level). For the first time, the actual modelling work takes place directly at the location of the building to be examined using AR smart glasses. An integral part of this innovative approach is the connection of all persons involved in the reconstruction process. A broad, interdisciplinary and transdisciplinary discussion expands the disciplinary expertise; the results of this collaborative work are directly to be implemented in the reconstruction. The aim of the project is to develop a working tool for the methodical application of this new approach. The testing and development of the tool is carried out within the framework of this project using the example of the imperial baths of Barbara in Trier.
