Systems and methods for automating conversion of drawings to indoor maps and plans

A computer-implemented method of creating an indoor map from a CAD drawing, the method comprising:

• preprocessing, by a device, an original CAD drawing to create a modified CAD drawing, a text database containing text from the original CAD drawing, a CAD vector-image of the modified CAD drawing, and a CAD raster-image of the modified CAD drawing;
• creating, by a device, a floor-level outline;
• sensing, by a device, furniture depicted on the floor, the sensing creates set of furniture entities;
• identifying, by a device, a room depicted in the CAD drawing by:
• applying the floor-level outline and the CAD vector-image to a first machine-learning algorithm to produce a room-level bounding line and a first probability distribution regarding identity of the room;
• applying the room-level bounding line and the text database to a second machine-learning algorithm to produce a second probability distribution regarding identity of the room;
• applying the first and second probability distributions to a third machine-learning algorithm to generate a room identity;
• and
• selecting, based on the room-level bounding line, a room-level outline;
• and
• creating, by a device, the indoor map for a floor using the floor-level outline, the room-level outline, and the room identity.
