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，丢失建筑状况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，并对澄清有关室内设计或建设性过程的问题做出决定性贡献，直到详细的解决方案。这些模型在内容上的意义和价值与真实的对象密切相关，但实际的建模过程却与之分离。借助增强现实（AR）的技术可能性，正是这种创建重建模型的过程首次直接与该项目中的调查对象联系在一起，从而重新定义了重建方法。增强现实的沉浸式效果，即真实的环境和虚拟内容的叠加，使得可以在三个现实层次中直接在对象上进行重建。因此，实际存在的建筑材料（第一级）与数字捕获的建筑材料（第二级）相关联，以便直接在对象（第三级）上构建虚拟重建。这是第一次，实际的建模工作直接在建筑物的位置进行，使用AR智能眼镜进行检查。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联系起来。一个广泛的，跨学科和跨学科的讨论扩大了学科的专业知识;这种合作工作的结果将直接在重建中实施。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，使用特里尔芭芭拉皇家浴室的例子。

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.
