Face recognition-based fatigue driving detection method

Abstract

The invention discloses a face recognition-based fatigue driving detection method. The method includes the following steps that: human face video image acquisition is carried out; an integral projection algorithm is adopted to carry out eye and mouth positioning on the first frame of image, the images of a left eye portion, a right eye portion and a mouth portion are extracted; an adaptive particle filtering-based eye tracking algorithm is adopted to carry out eye tracking; an improved horizontal projection-based eye and mouth state recognition method is adopted to carry out recognition; eye and mouth fatigue information extraction is carried out, a PERCLOS value, blink frequency, eye closing time and the number of times of yawning are calculated; and fatigue judgment is performed on a driver based on the PERCLOS value, the blink frequency, the eye closing time and the number of times of yawning. According to the defects of an original horizontal projection method, an improved horizontal projection method is adopted to recognize eye and mouth states, and therefore, high recognition accuracy and high adaptability can be achieved; and the fatigue judgment algorithm can improve judgment accuracy.

Description

technical field [0001] The invention relates to a fatigue driving detection method based on face recognition. Background technique [0002] Fatigue driving refers to the phenomenon of blurred vision, unresponsiveness, distraction, and stiff movements caused by factors such as long-term driving, lack of sleep, or physical discomfort. And the disorder of psychological function, appear the phenomenon that driving skill declines. If the driver does not have a good rest or drives for a long time, he is prone to fatigue. Once tired, the driver's attention, judgment, decision-making and motor awareness will be weakened. Improper time and other wrong operations can easily lead to traffic accidents. In order to ensure safety, fatigue driving should be strictly prohibited. [0003] According to the latest statistics, if the driver is inattention within 3 seconds, it will cause about 80% of traffic accidents, mainly including lane departure and rear-end collision accidents. The occur...

If the driver does not have a good rest or drives for a long time, he is prone to fatigue. Once tired, the driver's attention, judgment, decision-making and motor awareness will be weakened. If he continues to drive the vehicle, the action will be delayed or premature, and the operation will stop or correct Improper time and other wrong operations can easily lead to traffic accidents. In order to ensure safety, fatigue driving should be strictly prohibited

[0003] According to the latest statistics, if the driver is inattention within 3 seconds, it will cause about 80% of traffic accidents, mainly including lane departure and rear-end collision accidents. A large number of traffic accidents have seriously affected our harmonious life.
