Semi-automatic generation of bim models for cultural heritage

The building information modelling (BIM) platforms have serious difficulties to represent historical buildings and cultural heritage. These platforms have no libraries with historical parametric objects able to represent the particular characteristics of the historical buildings. One solution to represent faithfully the buildings is the use of point clouds obtained by laser scanning systems and photogrammetry. However, these clouds points, although they may represent faithfully the geometry of the buildings, are difficult to incorporate to BIM platforms because of the enormous volume of data they contain. Moreover, the particular nature of historic buildings makes it essential to incorporate semantic information including historical and bibliographic data of the analysed building.
