Embodiment Construction

[0051] like figure 1 As shown, the driver state monitoring method based on visual information fusion includes the following steps:

[0052] S10, collecting and preprocessing the driver's face image and the road image in front of the car.

[0053] Collect real-time images, collect real-time images of the driver's face by setting the infrared camera inside the car (and camera outside the car) collect real-time road images in front of the car, and transmit them to the image processing module for preprocessing. For example, according to the needs of the data format, the acquired The image is converted into a single-channel grayscale image, and operations such as filtering and noise reduction are performed.

[0054] S20, performing face positioning on the preprocessed driver's face image to obtain a face area.

[0055] as attached figure 2 As shown, to obtain the face area and eliminate the influence of hair and other parts on human eye detection, the specific method is as foll...

Abstract

The invention discloses a driver state monitoring method based on vision information fusion and a driver state monitoring system based on vision information fusion. The method comprises steps that: a driver face image and a road image in front of an automobile are acquired, and the images are pre-processed; face positioning on the pre-processed driver face image is carried out to acquire a face area; an eye pupil mass center and a pupil area in the face area are positioned to acquire eye state parameters, and eyes are tracked; track line detection and identification on the pre-processed road image in front of the automobile are carried out; according to a detected track line, an automobile driving direction and a navigation line included angle are calculated to determine whether the automobile deviates from the track; the driving state of the driver is discriminated according to the eye characteristics of the driver and the automobile deviation degree. The driver state monitoring method integrates two computer vision modes, improves detection efficiency, realizes real-time monitoring and alarm when the driver is under abnormal driving states, e.g., fatigue driving, after-drinking driving and driving with disperse attention, and thereby automobile safety driving is guaranteed.

Description

technical field [0001] The invention relates to traffic engineering, in particular to a driver state monitoring method and system based on visual information fusion. Background technique [0002] Drivers in an abnormal driving state can easily lead to road traffic accidents, so a safe and reliable vehicle driver status real-time monitoring system has far-reaching significance. [0003] At present, the existing driver state monitoring technology generally has the following methods: 1. The method based on the driver's physiological phenomenon; 2. The method based on the driver's manipulation behavior; 3. The method based on the behavior of the car; among them: [0004] The method based on the driver's physiological phenomenon mainly realizes the driver's status by measuring the driver's physiological signals such as heart rate, pulse, brain wave, electromyographic signal and other parameters changes or body movements including facial expressions, blinking frequency and other p...
