Embodiment Construction

[0019] Below in conjunction with embodiment the present invention will be further described.

[0020] The system as a whole includes the vehicle intelligent platform and the server side, such as figure 1 shown. The in-vehicle intelligent platform is based on the STM32 single-chip microcomputer with ARM core, and is wired to connect the high-definition camera, 3G / 4G module, display screen, speaker and power supply. The in-vehicle intelligent platform includes face detection algorithm, photo upload service and timing cycle algorithm, and the server side includes driver database and face recognition algorithm. The on-vehicle intelligent platform communicates with the server through a 3G / 4G data link; the display screen can preview the driver's photo in real time and display the time of the first timer and the second timer; the speaker can emit voice; the power supply is connected to the vehicle power system to Smart platform powered.

[0021] The invention divides the driver's...

Abstract

The invention discloses a driver fatigue state monitoring system and method based on face detection and identity verification. The system includes vehicle equipment and server. The on-board equipment uses the camera to obtain the image frame of the driver and uses the face detection algorithm for real-time detection. The result of the face detection is used to update the sleep time; according to the sleep time in different time periods, different abnormal states of the driver are handled. The server side is used to verify the identity of the driver. When the sleep time is at T 1 and T 2 In between, the on-board device sends the driver's image to the server to re-verify the driver's identity, and the driving time is updated according to the result of the identity verification. The driver fatigue state monitoring method provided by the present invention combines face detection and identity verification with two timers for fatigue monitoring, and realizes non-contact and real-time fatigue monitoring. The method is flexible, convenient and has high reliability and practicality.

Description

technical field [0001] The invention relates to a driver fatigue state monitoring system and method based on face detection and identity verification, belonging to the field of image signal processing. Background technique [0002] Driving fatigue refers to the imbalance of physiological and psychological functions of drivers after long-term continuous driving, and objectively, there will be a phenomenon of decline in driving skills. When the driver enters the process of fatigue driving state, it is almost always accompanied by obvious fatigue state characteristics. According to statistics, there are about 20,000 traffic accidents due to fatigue driving in my country every year. In 2003, my country's transportation department organized a test on the alertness of 516 drivers on expressways in the Beijing area. The test results showed that 10% of them had dozed off on the day of driving, and 10% of them had dozed off in the past driving process. 50%. It can be seen that fati...
