Video-based driver fatigue detection device

Abstract

The invention provides a video-based driver fatigue detection device, which comprises an infrared illumination component, a lens, a filtering component, an image capturing component and an image processing unit, wherein the infrared illumination component is used for providing infrared illumination for the monitored scene; the lens is used for acquiring the infrared optical image signal of the monitored scene; the filtering component is used for carrying out filtering treatment on the received infrared optical image signal of the monitored scene so as to highlight the face and pupils in the infrared optical image signal of the monitored scene; the image capturing component is used for converting the filtered infrared optical image signal into a digital image signal; and the image processing unit is used for extracting eyes and pupils from the acquired digital image and judging whether the driver is tired. By utilizing pupils to judge whether the eyes are open or closed, the video-based driver fatigue detection device of the invention effectively improves the accuracy of judging the open / close state of eyes, and then accurately and rapidly detects whether the driver is tired.

Description

technical field [0001] The invention relates to a video-based driver fatigue detection device, which belongs to the fields of image processing and video monitoring. Background technique [0002] Driver fatigue and lack of sleep are one of the important causes of serious traffic accidents, so it is of great significance to effectively supervise and prevent driver fatigue driving. Fatigue detection is a process of real-time detection and appropriate warning of driver fatigue during driving. It has the following requirements: 1) It must be non-interfering; 2) It must be real-time; 3) It must be illuminated 4) can not have harmful radiation; 5) can not include mobile devices. Among the various existing detection methods, the one that can meet the above requirements and have a more ideal effect is to use a camera to shoot in real time, and then use image processing to detect the physical reaction of the driver's eyes.
