Description

Vehicle eye control device with lighting source

technical field

The invention relates to an eye control device, in particular to an eye control device for a vehicle with an illumination light source designed with a separate light source.

Background technique

In recent years, the topic of ensuring driving safety has gradually received attention, and has become one of the key research projects of relevant manufacturers. To explore the causes of traffic safety accidents, most of them are caused by incorrect operation of driving, such as fatigue caused by lack of sleep in driving, driving for too long without proper rest, or talking on mobile phones, drinking alcohol, etc. driving and so on. In other words, poor mental conditions such as distraction and inattention are the main causes of car accidents.

In order to solve such problems, various technical solutions have been proposed. For example, Chinese Patent No. 200910310326.3 discloses a method of detecting the driver's eye area and hands on the steering wheel through image capture, and judging whether the driver's hands are placed on the correct area on the steering wheel and whether the eyes are open or not. Closed due to fatigue.

Another example is the paper proposed by Rochester Institute of technology, Jason S.babcock and Jeff B. Pelz: "Building a lightweight eyetracking headgear", which mentions a portable eye motion detection device, which is mainly configured with a camera on the spectacle frame , After obtaining the movement of the eyes, various applications can be performed.

Monitoring the condition of the eyes, avoiding traffic accidents caused by driving fatigue, or obtaining eye movement parameters for medical behavior or scientific research can all work reasonably and have certain effects. When analyzing and judging, misjudgments or failures often occur. The reason is that the main method of this type of technology is to obtain eye images through cameras, and use infrared light-emitting diodes, that is, IR LED lights, to irradiate the eyes to make the surface of the eyes reflect a bright spot. By judging the relative position of the bright spot and the pupil, Calculate the motion parameters of the eyes. Among them, the IR LED lighting is an important key in the technology. If the bright spot is too close to the pupil, or if the lighting is incorrect and causes deviation or even no bright spot, the movement of the eyes cannot be judged, and the device will also lose its function.
