Problems solved by technology

[0004] Some techniques for judging whether the user is in a fatigue state have been proposed in the prior art, but the equipment required for the judging techniques in the prior art is generally more expensive, the detection accuracy is not high, and it is more complicated to use. Therefore, the utilization rate of users is not high, and the cost is relatively high, and the user experience is relatively poor.

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Embodiments of the present invention provide a method for detecting fatigue state of a user. figure 1 Shown is a flowchart of a method for detecting user fatigue state in an embodiment of the present invention, as figure 1 As shown, the specific steps of the method for detecting user fatigue state in the embodiment of the present invention are as follows:

[0031] Step 11, acquire the user's facial features through face detection.

[0032] In general, the appearance of fatigue state is the result of a long-term accumulation. When the user is full of energy, the user's eyes are usually opened, the opening angle is relatively large, and the closing time is very short; As the frequency increases, the closing time also prolongs;...

Abstract

The invention provides a method for detecting the fatigue state of a user. The method for detecting the fatigue state of the user comprises the steps of obtaining the face features of a user through face detection, extracting the position information of the eyes of the user from the obtained face features, recording the closing times and the closing time of the eyes of the user in real time, calculating the recorded closing times and the closing time of the eyes of the user every a preset time period, obtaining the closing times and the closing time within a unit time period, and sending an alarming message to the user when the closing times or the closing time within the unit time period is larger than or equal to a preset threshold value. Through the method, the fatigue state of the user can be effectively detected, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of pattern recognition, in particular to a method for detecting fatigue state of a user. Background technique [0002] With the rapid development of science and technology and the improvement of people's living standards, people are paying more and more attention to their own health. However, due to the acceleration of the pace of life, people tend to be in a state of intense work for a long time, and because the attention is highly concentrated on the things currently being done, users often do not realize that they are already in a relatively tired state. [0003] According to the research results, it can be known that the state of fatigue will cause many adverse effects on people's various daily affairs. For example, when people are in a state of fatigue, traffic accidents are prone to occur. Studies have found that about 30% of traffic accidents are related to fatigue driving, so fatigue driving has be...
