Generating and validating a virtual 3D representation of a real-world structure

A system for forming a 3D model of a real-world structure, the system comprising:

• one or more processors;
• one or more non-transitory computer-readable media storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• for each image of a plurality of images of the real-world structure, identifying one or more landmarks in the image;
• providing metadata for the one or more identified landmarks of each image, the metadata for each landmark of the one or more identified landmarks specifying a shape of the landmark and a label for the landmark;
• correlating one or more of the identified landmarks in each image of the plurality of images with one or more identified landmarks in other images of the plurality of images;
• selecting, from a plurality of structure categories, one or more structure categories applicable to the real-world structure, wherein each structure category comprises structure data that defines an overall peripheral shape of structures belonging to the structure category, wherein selecting one or more structure categories applicable to the real-world structure is based, at least in part, on one or more of the identified landmarks;
• and
• generating the 3D model of the real-world structure based, at least in part, on:
• the identified landmarks,
• the correlations between the identified landmarks in different ones of the plurality of images;
• and
• geometrical constraints for the identified landmarks.
