Problems solved by technology

[0003] There are many existing driver fatigue detection methods. The detection method based on physiological signals uses EEG, ECG, EMG, breathing and other information. High staff dependence, poor real-time performance and high cost
The detection method based on the control behavior needs to detect the driver's various operations such as changes in the steering wheel, accelerator, and brakes.

Abstract

The invention relates to the technical field of traffic, in particular to a fatigue detection method and system based on image processing. The fatigue detection method based on image processing comprises the following steps: Step S1, face detection; Step S2, image processing; Step 3, data processing; and step S4, fatigue detection. Through cooperation of the face detection, image processing, dataprocessing, and fatigue detection, fatigue detection based on image processing is realized.

Description

technical field [0001] The invention relates to the technical field of traffic, in particular to an image processing-based fatigue detection method and a system thereof. Background technique [0002] At present, with the rapid development of social economy and the continuous acceleration of urbanization, the number of car users is increasing year by year, and the road traffic safety situation is deteriorating. The number of road traffic accident deaths in my country exceeds 60,000 people every year, and the average daily death toll exceeds 165. , ranks among the top in the world. According to the "National Road Traffic Accidents in 2016" issued by the Traffic Management Bureau of the Ministry of Public Security, in 2016, there were 212,846 road traffic accidents involving casualties, resulting in 63,093 deaths, 226,430 injuries, and direct property losses of 1.21 billion yuan. It can be seen that the problem of road traffic safety has seriously affected economic development ...
