Abstract: Various implementations provide a 3D floor plan based on scanning a room and detecting windows, doors, and openings using 2D orthographic projection. Points of a dense set of points (e.g., a dense point cloud) that are close to a plane representing a wall are projected onto the plane and used to identify windows, doors, and opening on the wall. Representations of the detected windows, doors, and openings may then be positioned in a 3D floor plan based on the known position of the wall within the corresponding room, i.e., the location of the wall plane relative to the dense point cloud is known. Other aspects of a 3D floor plan may be detected directly from points of a dense 3D point cloud, windows, doors, and openings may be detected indirectly using projections of the points of the 3D point cloud onto a 2D plane, and the detected aspects may be combined into a single 3D floor plan.
