METHOD AND SYSTEM FOR CHECKING DOZE AT THE VEHICLE

摘要

The present invention relates to a system for preventing drowsy driving by photographing a face of a driver driving a vehicle and operating a drowsy driving prevention alarm unit, including a camera photographing the face of the driver; a control unit outputting an image of the face photographed by the camera and executing an algorithm for determining the drowsy driving based on the image data outputted; and an alarm unit for warning the driver of the drowsy driving under to control of the control unit. The drowsy driving algorithm extracts an image of a pupil in a normal state, and calculates an area of the pupil. If the pupil image having an area smaller than a given ratio relative to that of the pupil in the normal state is extracted, the control unit operates the drowsy driving prevention alarm unit. The drowsy driving of the driver is automatically detected in real time by use of the image data while driving, without special manipulation of the driver or attaching a specific equipment to a body of the driver, and if the drowsy driving is verified by the algorithm, an warning signal is outputted to the driver, thereby preventing a traffic accident in advance.
