Monitoring method for smoking behavior of driver

Abstract

The invention relates to a monitoring method for a smoking behavior of a driver. The method comprises the steps of building a face detecting classifier and a nose detecting classifier; acquiring a driving state image of the driver on real time; accurately positioning an effective mouth detecting area of the driver from the driving state image; determining whether a cigarette is in the effective mouth detection area in the driving image state at the current frame. The method has the characteristics of being high in monitoring accuracy, small in detection mission and false mission rate, fast in speed and low in cost.

Description

technical field [0001] The invention relates to the technical field of safe driving, in particular to a method for monitoring a driver's smoking behavior. Background technique [0002] With the rapid growth of car ownership, road traffic has become more and more congested, and various traffic accidents occur frequently, especially the accidents of dangerous goods transportation and passenger transportation, and the losses caused by them are even more immeasurable. After studying its many reasons, it was found that smoking and driving was a special inducing reason. Because it is not prohibited by traffic laws like drinking and driving or talking and talking on the phone, and it is also a factor that people generally ignore. However, in fact, the harm it causes is no less than that of drinking and driving or driving on the phone, mainly in the following aspects: [0003] 1. When the driver wants to smoke, he will inevitably free up one hand to pick up the cigarette and relax...

AI Technical Summary

Problems solved by technology

When smoking, the driver usually holds the steering wheel with one hand and holds the cigarette with the other. Driving with one hand will cause the body to tilt involuntarily, causing the center of gravity of the vehicle body to shift, which will easily lead to irregular control of the steering wheel

The smoke exhaled will not only block the driver's sight, but also irritate the eyes, respiratory tract, and nostrils, causing blurred vision and coughing, seriously affecting normal driving

[0004] 2. After the effect of Nicola in cigarettes, there will be symptoms such as energy dispersion, uncoordinated movements, and fatigue

[0005] 3. The cigarette butts thrown out are basically ignited, which is easy to ignite roadside items. At the same time, due to the high-speed airflow, the cigarette butts are easy to scratch into the car again, causing a fire

The advantage of this type of method is that it does not rely on smoke and has high accuracy. The disadvantage is that in the actual environment, various heat sources and low ambient temperature will affect the sensitivity. Small, there will be some missed detection and false detection
