3D Restitution of cultural heritage monuments from ancient floor plans

摘要

In this paper, we present a complete set of algorithms for analyzing old ground plans of historical monuments, in order to build a 3D restitution of the corresponding monument. First, some image processing algorithms are used to analyze ground plans and extract a lot of infonnations such as thick and thin walls, openings, etc. The 3D model is then build by extruding the ground plans, and refined by adding textures from cut-offs and elevation images of the same collection of old plans. We applied our algorithms to ground plans of the Chateau de Versailles (XVIIIst century), providing us 3D models of two parts of the castle.
