Illustratively, the manner of obtaining the brightness threshold may include: the data model is constructed in advance, for example, the data model can be established in a mode of deeply learning and storing the brightness value in the vehicle through a computer, after the data model is established, through a driving experiment, when the brightness in the monitored vehicle is lower than a certain value, the illumination intensity of the environment at the driving seat cannot meet the shooting requirement of the camera 10, the collected image information is not complete enough, and then the value is set as the brightness threshold value. It should be noted that the above-mentioned method for obtaining the brightness threshold is only exemplary and is not a limitation to the present invention.

In some practical applications, in order to ensure the accuracy of the collected luminance signal in the vehicle, a plurality of luminance sensors 50 may be disposed inside the vehicle, and are respectively used for detecting the luminance of the environment in which the vehicle is located at different positions, and correspondingly, the main audio unit 23 may determine whether the infrared lamp control command needs to be generated currently by determining the relationship between the luminance average value output by the plurality of luminance sensors 50 and the luminance threshold value.

In this example, the audio host 23 may also be used to control the audio screen 22 to display the driving fatigue monitoring interface when the driving fatigue monitoring system 100 is activated.

Referring to fig. 3, the sound host 23 is further connected to the communication module 25, and is configured to collect a driving state reference image of the driver through the camera 10 when receiving the calibration instruction through the sound screen 22, and store the driving state reference image to the cloud server through the communication module 25, so as to compare the driving state reference image with image information when the driving state reference image is used for convenience, and determine whether the driver is in a driving fatigue state.

Further, in some examples, when different drivers appear, the driving state reference image of the cloud server may be updated in time according to driving behavior states of the different drivers, and agility calibration may be performed for the different drivers, so as to achieve reliability of the operation of the system 100.

As an example, the fatigue monitoring interface displayed on the audio screen 22 may also display a calibration mode button for receiving a calibration command.

For example, when a driver sits in a vehicle and starts the driving fatigue monitoring system 100, the audio screen 22 displays a driving fatigue monitoring interface, selects a calibration mode, and performs calibration work through corresponding guidance in the calibration mode. For example, the driver can simulate a normal driving state, and can perform information such as a midline of the driver's face, eyelid states (including upper and lower eyelid states and distances when the eyes are fully opened, eyelid states when the eyes are closed, half-open state of the eyes, and the like), a change in head height, turning around, making a call, and the like. Recognizing and inputting the information, performing comparative analysis in a memory 24 or a cloud server on the dangerous state or the driving fatigue state after state capture, and inputting the current driving state; when the subsequent driver drives again, only the face state needs to be recognized, secondary calibration is not needed, the workload of the driving fatigue monitoring system 100 is reduced, and the driving experience of the driver is improved.

For example, when the driver is found to be in a driving fatigue state currently according to the image information, in order to ensure driving safety, the main audio body 23 may change the background color of the instrument screen 61 to red completely through control, thereby reminding the driver.

Therefore, the driving fatigue monitoring system 100 provided by the example of the present invention stores the driving state reference image of the collected driver through the set memory 24 or the cloud server communicating with the communication module 25, and updates the driving state reference image of the cloud server in time when different drivers appear, the calibration logic is simple, agile calibration can be performed for the driving behavior states of different drivers, and the accuracy of driving fatigue state determination is ensured; meanwhile, by arranging the vehicle-mounted instrument 60, after the driver is judged to be in a driving fatigue state, the sound host 23 carries out deeper driving safety reminding on the driver by controlling the display state of the instrument screen 61; in addition, the infrared lamp 40 is arranged to assist the camera 10 to collect image information of the driving seat when the main audio system 23 acquires an infrared lamp control instruction, so that the driving behavior judgment effect is ensured, and the reliability of the system 100 in the working process is further improved.
