US 2021/0343073 A1 · GEOREFERENCING A GENERATED FLOORPLAN AND GENERATING STRUCTURAL MODELS

Abstract

Methods and systems for improved generation and georeferencing of floor plans are presented. In one embodiment, a method is presented that includes receiving images that depict sheets of a blueprint of a structure. Subsets of the images depicting floor sheets and elevation sheets may be identified. Exterior contours may be extracted from the images depicting floor sheets and elevation contours may be extracted from the images depicting elevation sheets. A corresponding structure within a three-dimensional map may be identified based on the exterior contours and the elevation contours. A three-dimensional contour of the exterior of the structure may be extracted from the three-dimensional map.

A method comprising:

receiving a plurality of images depicting sheets of a blueprint of a structure;
identifying a first subset of the plurality of images that depict floor sheets of the structure and a second subset of the plurality of images that depict elevation sheets of the structure;
extracting, from the first subset of the plurality of images, exterior contours of the floors of the structure;
extracting, from the second subset of the plurality of images, elevation contours of the structure;
identifying, based on the exterior contours and the elevation contours, a corresponding structure in a three-dimensional map of an area surrounding the structure;
and
extracting, from the three-dimensional map, a three-dimensional contour of the exterior of the structure.
