Lift the veil off the block samples from the Warcq chariot burial: CT-scan, photogrammetry, 3D printing and mixed reality

Abstract : Archaeological artefacts and the sediments that contain them constitute the sometimes tenuous evidence that requires analysis, preservation and showcased. Different methods of digital analysis that provide non destructive solutions to preserve, analyse and showcase archaeological heritage have been developed over recent years. However these techniques are often restricted to the visible surface of the objects, monuments or sites. The techniques used in medical imaging are more and more frequently used in archaeology as they give non destructive access to the artefacts' internal and often fragile structure. This use is mostly limited to a simple visualisation. The information obtained by CT-scan is transcribed in a visual manner and its inherent detail can be used much more widely in the domain of the latest 3D technologies such as virtual reality, augmented reality, multimodal interactions and additive manufacturing. In combining these medical imaging techniques, it becomes possible to identify and scientifically analyse by efficient and non destructive methods non visible objects, to assess their fragility and their state of preservation. It is also possible to assess the restoration of a corroded artefact, to visualise, to analyse and to physically manipulate an inaccessible or fragile object (CT, 3D printing) and to observe the context of our hidden archaeological heritage (virtual reality, augmented reality or mixed, 3D). The development of digital technologies will hopefully lead to a democratisation of this type of analysis. We will illustrate our approach using the study of several artefacts from the recent excavation of the Warcq chariot burial (Ardennes, France). We will present two types of physical interaction with inaccessible objects the first is based on a transparent 3D printing of a horse's cranium and the second is a more tangible interaction that combines 3D printing and virtual reality. We will highlight how this method can be integrated into the archaeological process whilst comparing it to existing methods. Its relevance and future research perspectives will also be discussed, in particular within the context of preventive archaeology.
