Embodiment Construction

[0073] It should be pointed out that the following detailed description is exemplary and intended to provide further explanation to the present application. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0074] figure 1 The realization process of the present invention is given.

[0075] A detection method for driver fatigue driving state based on micro-expressions, including:

[0076] Step (1): In order to obtain the driver's micro-expression, first collect the driver's facial expression image. The high-speed infrared camera installed at the rearview mirror is used to collect the driver's driving status video, and the driver's facial image information is obtained from it.

[0077] Step (2): Convert the collected image into a grayscale image, and perform histogram equalization on the image.

[0078] Step (21): Image gray scale tran...

Abstract

The invention discloses a detection method of driver fatigue driving status based on a micro-expression. The method includes the steps that a high-speed infrared camera in a vehicle is used to collecta driving state video of a driver, from which the face image information of the driver is obtained; preprocessing and feature extraction of the obtained image information are carried out, the micro-expression of the driver during the driving process is detected; the collected micro-expression of the driver is identified, the driving fatigue status of the driver is monitored based on the micro-expression, the fatigue status of the drivers or whether the driver is prone to driving fatigue or not, is pre-warned; pre-warning identification of the driving fatigue is achieved, it is avoided that aroad traffic accident is caused by a slow response, increased reaction time of the driver and even an occurrence of short sleep status to lose control to the vehicle due to deep fatigue driving.

Description

technical field [0001] The invention belongs to the field of driving safety protection, in particular to a method for detecting driver fatigue driving state based on micro-expressions. Background technique [0002] With the continuous progress of the social economy, the people's living standards are improving day by day, the demand for transportation is increasing day by day, and the number of motor vehicles on the road is increasing year by year. What follows is that the problem of road traffic safety in our country has become increasingly prominent, and traffic accidents have occurred from time to time, which has buried hidden dangers for public safety. In recent years, the number of vicious road traffic accidents in my country has been on the rise, seriously threatening the safety of people's lives and properties. Among the many traffic accidents, the traffic accidents caused by driver fatigue driving account for 20% of the total, and the proportion of serious traffic ac...
