Experiences with low and high cost 3D surface scanner.

The increasing importance of virtual techniques in archaeology and anthropology puts the question of adequate hardware and software applications for a digitalization of collections for museums and institutions into the focus. Especially the market for mobile 3D scanning developed rapidly during the last years and provides a range of different models suitable for scientific purposes today. As the requirements for archaeological and anthropological applications are very high and differentiated - due to the, in some cases very complex surface morphologies of the objects and the different textures from shiny obsidian to porous bone - the decision for a scanner model is often complicated. The Neanderthal Museum and the Royal Belgian Institute of Sciences have been testing six different surface scanner from four companies during the last months concerning their suitability for archaeological and anthropological objects. Quality of the 3D models was rated by the visibility and exactness of standard attributes used for classification of the object type in archaeology or anthropology. Results are presented here. Generally, all types of archaeological and anthropological objects can be digitalized with surface scanner. If a high end or a low budget model should be used depends on the texture of the object and the intended purpose.
