Problems solved by technology

The advantage of this type of method is that it does not need to touch the driver's body, and the test results can directly reflect the driving state. The disadvantage is that the judgment basis cannot be determined, and it is impossible to give a clear critical judgment threshold for different drivers.

Embodiment Construction

[0083] Below, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0084] Such as figure 1 As shown, in the embodiment, the system of the present invention includes an initialization module, an acquisition module, a positioning module, a tracking module, a detection module, and a voice communication module, and the detection method of the system includes the steps in the following order:

[0085] S1, execute the initialization module;

[0086] The function of the initialization module is to load the necessary face detection classifier files of the system.

[0087] S2. Execute the collection module;

[0088] The function of the collection module is to collect the driver's driving status image in real time, mainly the driver's head image, and transform it into a grayscale image.

[0089] S3. Judging the on-off state of the positioning module, if it is on, go to step S4, otherwise, go to step S6.

[0090] S4...

Abstract

The invention relates to a fatigued drive detection method based on mouth features. The fatigued drive detection method comprises the following steps that a face detection classifier is established; drive state images of a driver are collected in real time; the mouth of the driver is accurately positioned in the drive state images; in continuous video images, according to the position of the mouth in the image of the last frame, the position of the mouth in the image of the current frame is accurately predicted; according to the predicated position of the mouth, the position of the mouth is accurately positioned, the opening degree of the mouth of the driver is judged, and according to the ratio of the number of frames with large mouth opening degrees within unit time, whether the driver is in the fatigue drive state or not is judged; if the driver is in the fatigue drive state, an alarming reminding is conducted or a real-time video of the driver in the fatigue drive state is sent to a remote server, and a remote order is received. The fatigued drive detection method has the advantages that the monitoring accuracy is high, the leak detection and false detection rate is low, the environmental influence is small, the speed is high, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of safe driving, in particular to a fatigue driving detection method based on mouth features. Background technique [0002] Fatigue driving is one of the important causes of traffic accidents. Because it cannot be prohibited by traffic laws like drinking driving or driving on the phone, it is easy to be ignored by people. However, when the driver is in a state of fatigue , There will be distraction, reduced adaptability, untimely observation of road conditions and surrounding environments, and even short-term sleep, complete loss of driving ability, and extremely easy to cause traffic accidents. [0003] For traffic accidents caused by fatigue driving, due to the inability to detect the driver's fatigue driving state in real time, the regulatory departments of some passenger transport and freight companies cannot monitor and prevent them in advance. Therefore, real-time detection of the driver's fatigue dri...
