Method and system for detecting fatigue of automobile driver

Abstract

The invention discloses an automobile driver fatigue detection method and a system. The automobile driver fatigue detection method comprises the following steps: acquiring driver driving state pictureinformation, wherein the driving state picture information comprises driver head state information and driver hand state information; The driving state picture information is converted into data information by using a feature extraction method to obtain the driver's face feature parameters and the driver's hand motion feature parameters; Taking the driver's facial characteristic parameters and the driver's hand motion characteristic parameters as inputs of a BP neural network model to obtain a driver's fatigue level; Displaying a fatigue level of the driver. The selection of the invention cannot only overcome the shortcomings of the single index in detecting the driving fatigue degree, eliminate the misjudgment and missed judgment when the single index fails, but also improve the accuracy of identification.

Description

technical field [0001] The invention relates to the technical field of fatigue driving detection, in particular to a method and system for detecting driver fatigue. Background technique [0002] Driver fatigue is generally recognized as the main cause of traffic accidents leading to serious injury or death, and traffic accidents caused by fatigue driving account for about 20% of the total number and more than 40% of serious traffic accidents. According to relevant studies, if the driver is alerted one second before the traffic accident, 90% of similar traffic accidents can be avoided. [0003] Current means of detecting driver fatigue have the following disadvantages: [0004] The current detection method based on the driver's physiological indicators has strong objectivity and can accurately reflect the fatigue state of the human body. However, most physiological sensors are invasive and need to stick electrodes on the surface of the human body, which will not only cause d...
