One of the largest temple complexes in the world is located in Banteay Chhmar, Cambodia. However, many of the temple walls are currently only piles of stone blocks and many of the seemingly intact walls are in urgent need of new foundations. A new method was developed for the automated virtual reconstruction of a stone wall on the basis of 3D scans allowing to limit the moving of the nearly cube-shaped stones to a minimum during reconstruction work. In a first step, each high-resolution 3D stone model is reduced to its essential features, namely vertices, edges and faces. The method then suggests pairs of fitting stone blocks on the basis of the angle between adjacent surfaces. Finally, the expert has to validate the suggested fitting in a third step.
