Patent ID: 7054793

Claim:
A device for generating a virtual installation model as an image of a real installation, comprising: a first memory for storing picture data of the real installation; a second memory for storing information data of installation components of a component library; a third memory for storing the virtual installation model; and an evaluation-and-control-unit for comparing the information data of the installation components with the picture data of the real installation, for identifying identified components in the picture data as respective ones of the installation components, for deriving hypotheses regarding the identified components in the picture data, and for assigning the respective identified ones of the installation components to the virtual installation model, wherein the evaluation-and-control-unit is configured to control a building-up process of the virtual installation model, in which at least one of the installation components selected from the component library is dragged into a screen section that is assigned to display the picture data of the real installation, and wherein the evaluation-and-control-unit is configured to evaluate geometric properties of the picture data in order to reconcile the selected and dragged installation component with the identified installation components identified in the picture data of the real installation, and wherein, after a successful reconciliation, the selected and dragged installation component is assigned to a respective one of the identified installation components.
