Recording and documenting the chromatic information of architectural heritage

摘要: Abstract One essential approach in preserving architectural heritage is the documentation of 3D geometries and surface textures historic buildings. For example, precise colour information, excluding lighting effects, an intrinsic property materials building interiors exteriors. However, while information has been recorded for small sample areas, it not accurately documented on scale entire surfaces. This critical, because decay their colours fade with time. The goal this project to develop a method assist recording documenting chromatic exteriors buildings low cost high efficiency. takes advantage emerging dynamic range imaging (HDRI) technology, which can store rich about illumination through digital photography. By addition geometry texture obtained other existing technologies, we achieve more complete heritage.
