A system, device and method for preventing fatigue driving based on iris recognition

Abstract

The present invention belongs to a kind of iris recognition-based anti-fatigue driving system, device and method in the field of automobile safety driving; the anti-fatigue driving system includes an iris recognition unit, a central control unit, a timing module, an alarm module and an output module; the prevention Fatigue driving device comprises anti-fatigue driving system, fixed base, control signal output line, loudspeaker and warning lamp; The control method of described anti-fatigue driving device is through the iris information characteristic point and the storage iris information collected in the sampling time Comparing the feature points, calculating the coincidence degree Ci of each frame image and the coincidence degree within the sampling time. According to the size of the iris information coincidence degree C and the duration of the iris information coincidence degree <80%, prevent the fatigue driving device from making relevant responses; Monitoring driver fatigue through iris recognition has higher precision and accuracy than previous monitoring methods based on changes in facial expressions and physiological characteristics.

Description

technical field [0001] The invention belongs to the field of active and safe driving of automobiles, and in particular relates to a system, device and method for preventing fatigue driving based on iris recognition. Background technique [0002] With the increase of car ownership, the incidence of road traffic accidents is also increasing. my country's car ownership only accounts for 2%-3% of the world's total, but the number of deaths due to traffic accidents is nearly 20% of the world's every year. Therefore, my country is one of the countries with the most severe traffic problems in the world. A research report by the American Automobile Association Traffic Safety Foundation shows that fatigue driving accounts for 21% of traffic accident deaths. [0003] In the current technology for preventing fatigue driving, the driver's monitoring is usually based on the change of the driver's facial expression or physical condition to characterize the driver's fatigue condition, but...

Problems solved by technology

[0003] In the current technology for preventing fatigue driving, the driver's monitoring is usually based on the changes in the driver's facial expression or physical condition to characterize the driver's fatigue condition, but these monitoring methods are not accurate enough to judge the driver's fatigue condition

Iris recognition technology has the advantages of convenience, reliability, and high precision. At present, it is rarely used in the prevention of fatigue driving, and the relationship between existing research and practical applications is not close enough.

For example, the patent application with the application number 201510270928.6 discloses a method of motor vehicle iris recognition to prevent fatigue driving. Time is used as the basis for judgment, and the fatigue status of the driver is not considered in real time, so it is impossible to give early warning of fatigue driving in time
