Augmented Reality (AR) is a new form of human/computer interaction (HCI), whereby computer data is superimposed onto real life photographs and all kinds of information can be displayed to the operator depending on the content.
In this article, a possible application of AR technology, will be introduced using the example of the damage mapping carried out on the monumental sculpture "Bavaria" in Munich. Techniques such as AR have great potential in this area, especially when combined with a complete, laser scan recording of the 3D geometry of the object. Using this technique, the virtual object, whose precision depends on the quantity of measured points, can be superimposed with a 1:1 scale 3D photograph. Damage mapping can be carried out on the virtual object and on computer simultaneously, and then converted into a corresponding damage map. In this way, effective documentation, visualisation and structured data records are created, which can be managed in a content management system (CMS). The application is supported by 3D user interfaces, information filtering and automatic integration mechanisms.
We at ArcTron GmbH, are currently still in the development stage of this system. In the future, it will provide a 3D information system, specifically conceived for 3D documentation in archaeology and monument heritage at a variety of different levels.
