Method of generating orthoimages

A computer-implemented method for generating an orthoimage of a three-dimensional structure, particularly wherein the three-dimensional structure has predominantly vertical surfaces, the method comprising:

• receiving structure data relating to the three-dimensional structure, the structure data comprising at least first object data related to wanted objects and second object data related to unwanted objects, wherein wanted objects comprise features of the three-dimensional structure, and unwanted objects comprise objects that are situated near the three-dimensional structure and are not part of the three-dimensional structure;
• selecting, based on the structure data and at least partially automatically, a mapping area, the mapping area including at least a part of the three-dimensional structure;
• selecting mapping content, the mapping content comprising one or more wanted objects;
• and
• generating an orthoimage showing the mapping content, wherein selecting the mapping content comprises, at least partially automatically:
• specifying a three-dimensional mapping volume enclosing the mapping area, wherein the selected mapping content comprises wanted objects that are located in the mapping volume;
• and/or
• performing a segmentation of the surface data to identify wanted and/or unwanted objects.
