Fatigue driving detection method and system

Abstract

The invention provides a fatigue driving detection method and system, and relates to the technical field of safe driving, and the method comprises the steps: continuously collecting chest vibration signals of a driver; a heartbeat signal and a breathing signal of the driver are separated from the chest vibration signal; respectively carrying out feature extraction on the heartbeat signal and the respiration signal to obtain a corresponding heartbeat feature value and a corresponding respiration feature value; and inputting the heartbeat characteristic value and the breathing characteristic value into a fatigue driving classification model obtained by pre-training, and processing to obtain a fatigue detection result of the driver. The device has the advantages that thoracic cavity vibration signals are collected in a non-contact mode, body discomfort or secondary injury caused by contact of a driver is avoided, meanwhile, the reliability of a detection result of the thoracic cavity vibration signals is effectively improved due to the fact that the driver does not achieve far-end monitoring, and the reliability of the detection result is improved. Therefore, the detection reliability of the breathing signal and the heartbeat signal is improved, the accuracy of a fatigue detection result is improved, a driver can be early warned in time, and road safety accidents are reduced.

Description

technical field [0001] The invention relates to the technical field of safe driving, in particular to a fatigue driving detection method and system. Background technique [0002] With the progress of the times, the continuous development of society, the gradual improvement of people's living standards, and the requirements for better material enjoyment, in terms of travel, people's demand for motor vehicles is increasing, and at the same time, the accompanying road traffic accidents are also Increasing year by year, it is reported that a large number of traffic accidents occur every year, causing huge property losses and casualties to people all over the world [1]. How to reduce and avoid traffic accidents has become a difficult problem in China and even in the world. In the analysis of road traffic accidents every year, fatigue driving is one of the most common causes of road traffic accidents. Therefore, road traffic safety issues are increasingly causing people s concern...

Problems solved by technology

Among all known physiological characteristics, ECG (electrocardiogram) can collect physiological signals in a non-contact manner. However, the detection accuracy of the non-contact system is relatively low, and there are many detection artifacts and errors caused by human interference.
