Abstract:
A method of generating data representing a structure of a room on a device, the method including: outputting an audio signal at a first position in the room; acquiring a first reflection signal of the audio signal at the first position; outputting the audio signal at a second position in the room; acquiring a second reflection signal of the audio signal at the second position; estimating distance information about the room by using the acquired first and second reflection signals; acquiring at least one angle information about the room; and generating a floor plan illustrating the structure of the room using the estimated distance information and the acquired angle information.
