Fatigue or drunk-driving detection and control method and corresponding system

Abstract

The invention provides a fatigue or drunk-driving detection and control method and a corresponding system. According to the fatigue or drunk-driving detection and control method and the corresponding system, whether a driver drives in a fatigue or drunk state can be detected accurately, effectively and simultaneously, and thus corresponding control is carried out. The invention provides the drunk-driving detection and control method which comprises the following steps of: firstly, shooting a face of the driver to acquire a current eye image of the driver; and secondly, extracting a normal eye image of the driver, comparing the normal eye image with the current eye image, judging that the driver drives in the fatigue or drunk state if the ratio of the current eye image to the normal eye image exceeds a standard preset value and limiting the driving of the driver. Due to the adoption of the technical scheme provided by the invention, the fatigue and drunk-driving can be detected accurately, effectively and simultaneously and necessary driving limiting operation is carried out at the same time; and in addition, an image and an iris identification can be used as a reference for storage.

Description

technical field [0001] The invention relates to a fatigue or drunk driving detection and control method and a corresponding system, in particular to a fatigue or drunk driving detection and control method and a corresponding system using eye image scanning comparison. Background technique [0002] One of the reasons why safety accidents often occur when drivers are tired or drunk driving. Driving fatigue and drunk driving refer to the phenomenon that the driver's physiological function and psychological function are disordered when he is tired or drunk, and the driving skill declines objectively. Fatigue or drunkenness will affect the driver's attention, feeling, perception, thinking, judgment and movement. If you continue to drive a vehicle after being tired or drunk, you will feel drowsy, sleepy, weak in limbs, inattention, poor in judgment, or even appear in a trance or lose your instant memory, be late or premature in action, stop operation or correct time, etc. Unsafe ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many methods and technologies to prevent fatigue or drunk driving. For example, some methods simultaneously detect the driver’s grip on the steering wheel, the steering wheel’s angle of rotation, the driver’s skin current, the driver’s breathing depth and frequency, and the depth of the accelerator. Judging by the data, the device designed by this type of method has a complex structure and high price. For example, the patent document with the application number 200710051344.5 and the name "Automobile Driver Fatigue Real-time Detection System" discloses a

Although some are simple, they are not very reliable. For example, the patent No. is 200620032537.7, and the patent document called "automobile anti-fatigue driving alarm" discloses a simple method for reporting to the police when the head touches the sensor when people doze off, but It has the following deficiencies: 1. If you accidentally bump into it, you will report to the police by mistake, so the alarm is not accurate. The alarm is not timely

The alcohol test can only determine whether the person who blows into the instrument has drunk alcohol or whether someone around the sensor has drunk alcohol, but cannot determine the identity of the driver

Therefore, if the driver asks someone else to blow his breath or the driver himself did not drink, and the person next to him drank a lot of alcohol, a misjudgment may occur, and these situations cannot be used as a punishment for drunkenness in the existing drunkenness judgment methods. accurate evidence of driving
