Embodiment Construction

[0073] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the application. Unless otherwise defined, 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] Micro-expression-based driver fatigue driving state detection method, 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 state video, and obtain the driver's facial image information from it.

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

[0078] Step (21): the image grayscale transformation includes linear ...

Abstract

The invention discloses a method for detecting the driver's fatigue driving state based on micro-expressions, which includes: using a high-speed infrared camera in the car to collect the driver's driving state video, and obtaining the driver's facial image information; Processing and feature extraction to detect the driver's micro-expressions during driving; identify the collected driver's micro-expressions, monitor the driver's driving fatigue state based on the micro-expressions, and warn the driver's fatigue state or whether There is a tendency to drive fatigue; realize the early warning and recognition of driving fatigue, and avoid the driver's reaction slowdown and reaction time increase due to deep fatigue driving, and even short-term sleep state and loss of control of the vehicle causing road traffic accidents.

Description

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