Embodiment Construction

[0037] To further illustrate the various embodiments, the present invention is provided with accompanying drawings. These drawings are a part of the disclosure of the present invention, which are mainly used to illustrate the embodiments, and can be combined with related descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should understand other possible implementations and advantages of the present invention. The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0038] refer to figure 1, the overall flow of the method of the embodiment of the present invention. It mainly includes the collection of face images, the detection and recognition of face images, the acquisition of features and parameters, the judgment of fatigue degree and the alarm of fatigue state.

[0039] In the process of detecting face images, t...

Abstract

The invention provides a fatigue driving prewarning method and system.The method and system judge the fatigue degree based on multiple facial features such as the nodding frequency, eye closing percentage and mouth shape.The method mainly includes the steps of acquisition of face images, detection and recognition of the face images, feature and parameter acquisition, judgment of the fatigue degree and alarming of the fatigue status.The face features are collected, and therefore the problem that the precision degree is not high obviously when the fatigue status is judged through a single parameter is effectively avoided.

Description

technical field [0001] The invention relates to the field of car navigation, in particular to a fatigue driving monitoring and reminding method and system. Background technique [0002] Generally speaking, fatigue driving is the phenomenon of drowsiness, drowsiness, weakness of limbs, lack of concentration and obvious decline in judgment ability after driving for a long time. In severe cases, there may even be trance and momentary memory loss. Although the time for the driver to doze off while driving is only a few seconds, it is enough to instantly cause serious traffic accidents. Therefore, the harm caused by fatigue driving cannot be underestimated. [0003] The most accurate techniques currently available are methods based on physiology, such as brain waves, heart rate, pulse rate, and breathing, among others. These technologies are intrusive because they require electrodes to be attached to the driver, which tends to cause them emotional annoyance. In order to work w...
