Problems solved by technology

This method is a non-contact detection method. The detection equipment is easy to install and has strong operability. However, this method needs to customize the fatigue state judgment conditions, and because everyone’s blinking habits are different, this is self-knowledge. The defined fatigue state judgment conditions do not necessarily match each user, and it is easy to cause misjudgment

Embodiment Construction

[0044] Below with reference to the accompanying drawings, through the description of the implementation examples, the specific embodiments of the present invention, such as the shape, structure, mutual position and connection relationship between each part, the role and working principle of each part, etc., will be further described. detailed instructions.

[0045] Such as figure 1 As shown, a structural diagram of a fatigue judgment system, which includes a standard data set, an acquisition unit, a calculation unit, a judgment unit, and an alarm unit. The standard data set and the acquisition unit are connected to the input end of the calculation unit, and the output end of the calculation unit The input end of the judging unit is connected, and the output end of the judging unit is connected to the alarm unit.

[0046] The standard data set is to obtain the characteristic parameters of the subject under non-fatigue state, and form a standard set according to the characteris...

Abstract

The invention provides a fatigue judging system and method to reduce erroneous judgment of fatigue driving. The system comprises a standard data set, an acquisition unit, a calculation unit, a judging unit and an alarm unit. Compared with the prior art, the system and the method have the advantages that a number of non-fatigued feature parameters are respectively acquired; the acquired feature parameters form the standard set; in a judging process, the state feature parameter of a detected person is acquired in unit time in real time, and at the same time the state feature parameter and the standard set are compared; whether the detected person is fatigue is comprehensively judged; the judgment accuracy of fatigue driving is improved; and a driver is timely reminded in a fatigue driving process to avoid traffic accidents.

Description

technical field [0001] The invention relates to the technical field of electronic systems, in particular to a fatigue judgment system and method. Background technique [0002] Fatigue driving detection belongs to the category of active safety, and there are many methods for fatigue driving detection, such as facial expression, body movement detection, muscle condition, eye opening and closing state, steering wheel angle detection, etc. At present, the research on fatigue detection system can be divided into two kinds of methods, one is based on hardware, and the other is based on computer vision. [0003] The hardware-based method involves the research and design of physical hardware, such as electrooculogram, electromyography, and electroencephalogram measurement. Although this method can obtain accurate results for fatigue judgment, the hardware used in this type of method It must be in contact with the human body, and the operability is not strong in practical applicatio...
