  • Publication number: 20220165089
    Abstract: In an alcohol detection system, face authentication is performed on a person to be measured before an alcohol detection device starts measurement, and the success of the face authentication performed on the person to be measured triggers the acquisition of camera image information that are images of the face of the person to be measured continuously shot by a camera. In other words, when the face authentication performed on the person to be measured succeeds, the person to be measured starts alcohol detection and images of the face of the person to be measured are continuously shot during the measurement.
