Abstract

본 발명은 촬상관(CCD)을 사용하여 차량 운전자의 눈 상태를 감시하고, 제어부에서는 차량의 속도를 감지하여 운전자가 졸음 운전 중이라 판별되면, 경보를 울려 졸음 운전을 방지토록 하는 차량에서 졸음운전 방지장치 및 그 구현방법에 관한 것으로, 차량의 앞면에 있는 거울과, CCD 카메라를 이용하여 운전자의 눈 상태를 감시하고, 감시 결과 운전자가 졸고 있으면 경보를 울려 졸음에서 깨어나도록 하므로써, 졸음으로 인해 발생하는 교통 사고를 미연에 방지하도록 한다.The present invention monitors the eyes of the driver of the vehicle using an imaging tube (CCD), and if the control unit senses the speed of the vehicle and determines that the driver is drowsy driving, an alarm sounds to prevent drowsy driving in the vehicle to prevent drowsy driving. The present invention relates to a device and a method for implementing the same, wherein a mirror on the front of a vehicle and a CCD camera are used to monitor the driver's eye condition, and if the driver is asleep, an alarm is issued to wake up from sleepiness. Prevent traffic accidents in advance.
