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.
Claims20
A method comprising:
- receiving a plurality of images depicting sheets of a blueprint of a structure;
- identifying, based on the plurality of images, exterior contours of floors of the structure and elevation contours of the structure;
- and
- extracting, based on the exterior contours and the elevation contours, a three-dimensional contour of an exterior of the structure from a three-dimensional map.
A system comprising:
- a processor;
- and
- a memory storing instructions which, when executed by the processor, cause the processor to perform operations including:
- receiving a plurality of images depicting sheets of a blueprint of a structure;
- identifying, based on the plurality of images, exterior contours of floors of the structure and elevation contours of the structure;
- and
- extracting, based on the exterior contours and the elevation contours, a three-dimensional contour of an exterior of the structure from a three-dimensional map.
