Patent ID: 11514633

Abstract:
Automating conversion of drawings to indoor maps and plans. One example is a computer-implemented method comprising: preprocessing an original CAD drawing to create a modified CAD drawing, a text database, a CAD vector-image, and a CAD raster-image; determining a floor depicted in the CAD drawing by applying the CAD raster-image, the CAD vector-image, and the text database to a floor-level machine-learning algorithm resulting in a floor-level outline; sensing furniture depicted on the floor by applying the floor-level outline, the CAD vector-image, and the text database to a furniture-level machine-learning algorithm resulting in a set of furniture entities; identifying each room depicted in the CAD drawing by applying the floor-level outline, the furniture entities, CAD vector-image, and the text database to room-level machine-learning algorithm resulting in a plurality of room-level outlines; and creating an indoor map by combining the furniture entities and the plurality of room-level outlines.
