DEVICE AND METHOD FOR DETECTING DRIVER'S CONDITION USING INFRARED RAY SENSOR

摘要

A device for detecting driver's condition is provided. More specifically, an infrared ray (IR) sensor which includes a light-emitting unit that emits a light signal, and a light-receiving unit that receives the light signal, measures a distance to an obstacle in front of the IR sensor using a phase difference between a light signal emitted from the light-emitting unit and a light signal received by the light-receiving unit. Additionally, a camera photographs a driver's face and detects the driver's face from the photographed image. An electronic controller then determines whether a recognition error has occurred using data measured by the IR sensor and the camera, and analyzes a generated recognition error when a recognition error occurs.
