[0052] An embodiment of the present invention provides a fatigue driving detection method, which is used to detect whether the driver is in a state of fatigue driving, and when the driver is in a state of fatigue driving, a corresponding reminder is given to ensure the safety of the driver and passengers. see figure 2 , is a flowchart of a fatigue driving detection method provided by an embodiment of the present invention. The fatigue driving detection method includes:

[0053] Step S201: Obtain detected face image information.

[0054] Understandably, after the image collection module 105 collects the driver's image information, it transmits the image information to the processor 103, and the processor 103 can detect the driver's face image information through a preset face recognition mode.

[0055] Step S202: Calculate the offset of the center of gravity of the driver's head based on the face image information.

[0056] It should be noted that the offset of the center o...

Abstract

The embodiment of the present invention provides a fatigue driving detection method and device and relates to the technical field of fatigue recognition. The method comprises a step of acquiring detected face image information, a step of calculating an offset of a center of gravity of a head of a driver and an effective number of closing eyes of the driver in a unit time based on the face image information, and a step of determining a driving state of the driver according to the offset of the center of gravity of the head and the effective number of closing eyes. Whether the driver is in a fatigue driving state or not can be accurately judged by integrating the offset of the center of gravity of the head and the effective number of closing eyes to reduce cases of misjudgment, and the safety of the driver and passengers is guaranteed to a greater extent.

Description

technical field [0001] The present invention relates to the technical field of fatigue recognition, in particular to a fatigue driving detection method and device. Background technique [0002] Fatigue driving is an important cause of traffic accidents. How to effectively monitor and prevent driver fatigue driving has very important practical significance for reducing traffic accidents and death rates. [0003] However, the current market models only judge whether the driver is in a fatigued driving state through the driving time in the navigation. The intelligence level is relatively low, and the driving state of the driver cannot be accurately judged, and there is a large safety hazard. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a fatigue driving detection method and device to solve the above problems. [0005] In order to achieve the above object, the technical solution adopted in the embodiment of the present...
