Problems solved by technology

[0003] The above-mentioned various methods and systems at home and abroad have made great progress in monitoring and alarming systems for fatigue driving, but there are more or less the following three problems: 1. Often only a certain fatigue feature is considered
In fact, because different drivers have great individual differences, and each fatigue assessment method has different emphases, various specific methods that only consider one fatigue ...

Embodiment Construction

[0026] Referring to Figure 1, a CMOS camera 1 (Hyundai HY 100A) and a near-infrared light source 2 (Pacific Cybervision CV100D) are installed near the position of the steering wheel 5 in front of the driver in the cab. The light source only contains the infrared light source of the corresponding wavelength (wavelength 850nm). When using infrared lighting, the driver's face is clearer, and objects farther away from the light source are almost filtered out. Image processing is less difficult. Considering the real-time problem of image analysis, the size of the collected image is set as 320*240. The size of the driver's face image is adjusted to approximately 10,000 pixels.

[0027]An embedded system 3 is also installed on the car to continuously capture the driver's frontal image of the head. The embedded system 3 judges the lighting conditions of the environment, automatically determines whether to turn on the infrared lighting source 2, and performs corresponding operations...

Abstract

This invention discloses a system and a method for monitoring fatigue of driver based on image process and information combination technology, first of all a camera head collects continuous digital signals, tests position of the drive face and further decides positions and sizes of eye, pupil and mouth, then determines the PERCLOS, frequency of yawning, rule of head shaking, gazing direction and time of the eyes and turns the four measurement values to fatigue degree and finally uses the information combination technology to combine the information of the four characters, when his fatigue degree exceeds a set value, the alarm starts up warning.

Description

technical field [0001] The invention relates to a driver fatigue monitoring system and method based on image processing and information fusion technology. Background technique [0002] At present, there are many related researches on "driving fatigue detection" at home and abroad: "Driver Fatigue Level Detector" developed in Austria. It can accurately record the change frequency of the driver's pupil diameter for the tester to judge the driver's fatigue and the danger of driving. "Fatigue detection glasses" developed in Australia. The infrared sensor can detect the driver's eyelid activity and blinking frequency, so as to judge whether the driver is already in a state of fatigue. In addition, there are two alarms in the metal box connected to the glasses, which can remind the driver in time that "it is time to rest" and "you are already in a state of fatigue". In 1998, Zhou Peng of Shenzhen Long-distance Bus Company applied human psychology, modern neurology, and electron...
