Approach for an update method for digital factory models

The requirements of factory planning and the building concerned have changed in the last years. Factory planning has the task of designing products, plants, processes and the building of a factory. Although the building has an indirect influence on manufacturing systems, a quick conversion of the building is crucial in the event of changes in production technology. A current digital building model of the factory enables to carry out conversion processes quickly. The approach develops a method to update a digital building model of a factory during operation. Photogrammetry is used to update point clouds and derive BIM models.
