Abstract

The invention discloses face detection method and system for detecting driver fatigue. The method comprises the following steps of: image preprocessing: greying a color image and reducing the image resolution; image processing: acquiring a connected region and an integral image, wherein the acquisition of the connected region is realized by carrying out image binaryzation, edge image extraction, face region decomposition and connected region analysis on the current frame image, and the acquisition of the integral image is realized by carrying out image difference on every two adjacent frame images; selecting the face region of the candidate according to the acquired connected region and integral image; and verifying the face region of the candidate, filtering out the required false face region by using the judgment conditions, and outputting the face region. The invention can be used for detecting driver fatigue, realizes the driver's face detection, and has the advantage of simple and quick detection.

Description

technical field

[0001] The invention relates to video surveillance technology, in particular to a face detection method and system for driver fatigue detection. Background technique

[0002] Driver fatigue and lack of sleep are one of the important causes of serious traffic accidents. Statistics show that traffic accidents caused by fatigue / drowsiness account for about 7% of the total number of traffic accidents, 40% of serious traffic accidents, and 35% of traffic accidents on heavy trucks and highways. Therefore, it is of great significance to effectively monitor and prevent driver fatigue.

[0003] 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) No harmful radiation, not including mobile devices.

[0004] Among the various detection methods that can meet the above requirements and the eff...
