Method and device for generating a digital model of a building

A computer-implemented method for generating a digital building model, the method comprising:

• a) reading in an initial building model;
• b) extracting a creator indication about a creator of the initial building model from the initial building model using a pattern recognition method;
• c) selecting a creator-specific object pattern library from a multiplicity of creator-specific object pattern libraries based on the creator indication, and loading the creator-specific object pattern library in which a respective object pattern has an assigned building element data record;
• d) correlating the respective object pattern with objects of the initial building model by a pattern recognition method;
• e) assigning an object correlating with the respective object pattern the building element data record assigned to the object pattern as an annotation;
• and
• f) generating and outputting an annotated digital building model, wherein the initial building model and the assigned annotations are taken as a basis for the generating and outputting the annotated digital building model;
• wherein a local correlation of a further object with a further annotation is captured in the initial building model by the pattern recognition method and stored in the creator-specific object pattern library in a manner assigned to one another so that the creator-specific object pattern library is expanded in the course of operation of the computer-implemented method.
