Smart Home Floor Map Generation Applications Based on Image Recognition

In this paper, we propose new smart home applications generating user's home floor plan and detecting devices, furniture, doors, and windows based on the image recognition of a panorama image and a hand sketch image. To generate a floor plan from a hand sketch diagram, vectorized house layout is generated after recognizing line, corner angles, and door/windows within 1.2 seconds. To calculate room shape and size on floor map generation from a panorama image, we predict the ceiling-wall boundary line of the image, where the errors of the estimated room size are less than 0.5 meters. The generated floor map on smartphone including device information and localization can be shown at the large screen devices such as smart TV or monitor.
