One of the most important areas of research and activity of our group is the digitization of cultural heritage . We are using several specialized systems and we have developed several techniques and methods for correlating imaging data investigation. The central element is represented by a monochrome 3D laser scanning device. Amongst our 3D scanning field campaigns it is worth mentioning the Ladakh (India) in the summer of 2008, Basarabi ensemble (Romania) and the churches: Fundenii Doamnei, Sucevita, Gura Humorului, Curtea de Arges (all in Romania) and others. These digital three dimensional models are processed and then delivered in different forms depending the purpose. In some cases it is required to observe some characteristics of a certain investigation technique on the 3D surface, so we can process the digital models and the investigation data into 3D virtual worlds where the user can digitally manipulate the models and observe small details and the investigation data on the object's surface. For other purposes we can also 3D print the models, with or without graphical information overlapped on the surface of the object.

During our field campaigns we usually set up microclimate sensor networks, either we are asked to or not. It is important though to know the exact microclimate conditions of the artworks or monuments in order to take important decisions regarding their conservation state. We currently have three different sensor networks that can measure temperature and relative humidity. One of these, the intelligent wireless network can also measure pollutants in the atmosphere.
