Method for recognizing road rage states of drivers on basis of electroencephalography and pulse information

Abstract

The invention discloses a method for recognizing road rage states of drivers on the basis of electroencephalography and pulse information. The method includes steps of 1), acquiring pulse informationand electroencephalography signals of the drivers and preprocessing the pulse information and the electroencephalography signals; 2), extracting features of the pulse information and the electroencephalography signals of the drivers; 3), fusing electroencephalography features and pulse features of the drivers and reducing dimensions of the electroencephalography features and the pulse features; 4), training driver road rage state discrimination classifiers; 5), judging the road rage states of the drivers in real time, to be more specific, judging the road rage states of the drivers by the trained road rage state discrimination classifiers in real time and prompting the drivers when judgment results are 'yes'. The step 1) particularly includes (1), acquiring the pulse information of the drivers by wrist strap type terminals and preprocessing the pulse information; (2), acquiring the electroencephalography signals of the drivers by head-mounted terminals and preprocessing the electroencephalography signals. The step 2) particularly includes (1), extracting the features of the pulse information of the drivers; (2), extracting the features of the electroencephalography signals of the drivers. The method has the advantage that the problems of high power consumption and susceptibility to external conditions in the prior art can be solved by the aid of the method.

Description

technical field [0001] The present invention relates to a method belonging to the field of traffic safety driving and intelligent technology, more precisely, the present invention relates to a driver's road rage recognition method based on the integration of EEG signal processing and pulse information processing. Background technique [0002] "Road rage" is a kind of driving anger caused by frustration and pressure. It belongs to paroxysmal rage disorder. The driver will actively obstruct, provoke and other excessive behaviors, endangering the safety of others and himself. According to statistics, the proportion of traffic accidents caused by violent driving behavior is becoming more and more serious. Studies have shown that quite a lot of drivers have these symptoms, but not everyone can have a clear understanding of their emotions during the onset of symptoms. If driving emotions cannot be detected and eliminated in time, they will deteriorate into traffic accidents. Ther...
