The present invention relates to a system for preventing drowsy driving, which rapidly realizes a drowsy state of a user and alarms the state, releases a drowsy state even if the user does not disperse eyes or movements of the user when the drowsy state is erroneously determined, recommends proper rest to the user who suppresses drowsiness when driving a vehicle, and induces safe driving by obstructing the user from re-driving the vehicle without enough rest. The system for preventing drowsy driving, comprises: a camera installed in the vehicle to photograph the user; a control part which detects blinking eyes of the user by receiving an image photographed by the camera, detects a drowsy state of the user from blinking eyes of the user, and transmits a control signal to an electronic control unit (ECU) in accordance with a determined result. The control part is characterized by obtaining a face outline of the user from the image; calculating positions of both eyes from the obtained face outline; and obtaining pupil outlines of the both eyes from the positions of the calculated both eyes. In regards to this, if the pupil outlines are not obtained from the positions of the pupil outlines with respect to the face outline, it is considered as closing eyes of the user. Also, if the number considered as closing eyes rapidly changes in comparison to the average number of closing eyes, it is considered as drowsy driving.

    본 발명은 사용자의 졸음 상태를 신속히 파악하여 경보하고, 졸음 상태의 판별에 오류가 발생한 경우 사용자의 시선 및 동작을 분산시키지 않아도 이의 해제가 가능하며, 졸음을 억지로 참으며 운전하는 사용자에게 적절한 휴식을 권장하고, 사용자가 충분한 휴식을 취하지 않고 재운행을 시도하지 못하도록 하여 안전한 운행이 될 수 있도록 하는 졸음 운전 예방 시스템에 관한 것으로서, 차량 내부에 설치되어 사용자를 촬영하는 카메라; 상기 카메라로부터 촬영된 화상을 입력받아 상기 사용자의 눈 깜빡임을 감지하고, 상기 사용자의 눈 깜박임으로부터 상기 사용자의 졸음 상태를 판별하며, 판별된 결과에 따라 ECU에 제어 신호를 전송하는 제어부;를 포함하되, 상기 제어부는, 상기 화상에서 상기 사용자의 얼굴 윤곽선을 획득하고, 획득된 얼굴 윤곽선으로부터 양 눈의 위치를 추정하며, 추정된 양 눈의 위치로부터 양 눈의 동공 윤곽선을 획득하되, 상기 얼굴 윤곽선에 대한 상기 동공 윤곽선의 위치에서 상기 동공 윤곽선이 획득되지 않는 경우 이를 상기 사용자가 눈을 감은 것으로 판단하며, 눈을 감은 것으로 판단된 횟수가 평균치로부터 급격히 변화한 경우 졸음 운전으로 판단한다.
