Abstract

The present invention provides a method and device for detecting fatigue driving. The method includes: collecting camera visual information and vehicle operation information in real time; The second eigenvalue of the behavior feature; calling the previous fatigue index value, and calculating the current fatigue index value according to the previous fatigue index value, the first eigenvalue and the second eigenvalue; judging whether the current fatigue index value is greater than the fatigue index threshold; If yes, it is determined that the driver is in a fatigue driving state; if not, it is determined that the driver is not in a fatigue driving state. Based on the method disclosed in the present invention, fatigue driving can be accurately detected without interfering with the driver's normal driving, while taking into account detection accuracy and driving safety.

Description

technical field [0001] The invention relates to the technical field of automobile driving safety, and more specifically, relates to a fatigue driving detection method and device. Background technique [0002] In recent years, with the rapid increase of car ownership and motor vehicle drivers, road traffic safety has become a social focus, and fatigue driving is the main cause of traffic accidents. [0003] At present, the detection of fatigue driving mainly includes facial feature detection and physiological index detection. If facial features are used, such as eye movements, facial expressions, etc., it is necessary to collect the driver’s facial image. However, due to the limitations of the driver’s head position and the light in the cab, the collected facial image is likely to be unclear. Affect the accuracy of subsequent detection; and if using physiological indicators, such as ECG data, respiratory rate, etc., the driver needs to wear relevant equipment, which may inte...
