For planning structural changes at and/or in existing industrial plants and for the documentation of structural facilities the knowledge of existing geometry is of great importance. The structural facility, the material world object, must be transferred in a planning and/or a documentation system. Photogrammetry and laser scanning simultaneously used in a combined system offers high speed data capture of the geometry and details of the scene. The captured data are used for the extraction of geometric primitives namely points, lines and surfaces, which are combined, forming a model of the object. Presented is the combined modeling of laser scanning and photogrammetric data in PHIDIAS modeling system
