System for adjusting sensitivity of fatigue driving early warning system in self-adaptive mode

Abstract

The invention discloses a system for adjusting the sensitivity of a fatigue driving early warning system in a self-adaptive mode. The system comprises an information collecting module, an information processing module and an early warning device module. The information collecting module is used for collecting a driver face image sequence. The information processing module is used for conducting processing and analyzing on the collected driver face image sequence to obtain expression feature information of a driver, a corresponding fatigue early warning sensitivity mode is automatically started according to the initial driving time and the continuous driving duration and whether the driver is in a fatigue driving state is not is judged according to fatigue judgment parameters set in advance according to the mode. The early warning device module is used for conducting early warning prompting on the driver in the mode of voice according to the fatigue level when the driver is in the fatigue driving state.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a system for adaptively adjusting the sensitivity of a fatigue driving warning system. Background technique [0002] With the increase of car ownership and improper extension of highways, car traffic accidents are increasing, and the road traffic safety situation is becoming increasingly severe, causing a large number of casualties and huge economic losses, and social problems emerge in endlessly. Surveys show that fatigue driving is one of the main causes of many accidents, and more than 20% of accidents that cause personal injury or even death are caused by fatigue driving. When the driver is tired, his ability to perceive the surrounding environment, judge the situation and control the vehicle is greatly reduced, and traffic accidents are extremely prone to occur. With the enhancement of people's safety awareness and the advancement of science and technolog...

Problems solved by technology

[0005] In view of the current fatigue driving detection technology, the parameter threshold for judging the occurrence of fatigue at different time periods is single, resulting in false detection and missed detection. The present invention proposes an adaptive adjustment fatigue detection technology. The sensitivity system of the driving warning system, according to the different time periods of the day and the length of driving time, the difference in the driver's mental state leads to the difference in the probability of fatigue driving, adaptively adjust the sensitivity of the fatigue driving warning system, set different fatigue judgment parameter thresholds, change The general method of setting parameter thresholds in existing products and technologies reduces the occurrence of false detections and missed detections
