Abstract: Disclosed herein is an apparatus and method for measuring quality of audio. The apparatus includes a distorted signal generation unit, an extraction unit, a distortion level measurement unit, a distortion function generation unit, and a search and measurement unit. The distorted signal generation unit generates a plurality of distorted signals with respect to audio in compliance. The extraction unit extracts a fingerprint and AV information corresponding to the audio and fingerprints and AV information corresponding to the plurality of distorted signals. The distortion level measurement unit measures fingerprint distance differences, and arousal and valence (AV) distance differences. The distortion function generation unit generates a fingerprint distortion function and an AV distortion function. The search and measurement unit measures the quality of the audio by extracting a fingerprint and AV information from query audio and then comparing extraction results with the fingerprint distortion function or AV distortion function.

Abstract: Provided are a method and apparatus for generating ultra-high-quality digital data. A method for generating digital data includes identifying information on a target disposed at a specific position, controlling a movement of a first device to photograph two-dimensional image data for a partial region of the identified target, determining whether the two-dimensional image data for the partial region of the target photographed through a camera mounted on the first device corresponds to an entire region of the target, and controlling a movement of a second device loaded with the target when the two-dimensional image data for the partial region of the photographed target does not correspond to the entire region of the target.
