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

Embodiment Construction
[0077] Further illustrate the present invention below in conjunction with accompanying drawing.
[0078] Such as figure 1 As shown, the system based on the monitoring method of the present invention includes an initialization module, a collection module, a positioning module, a detection module and a communication module. In each embodiment of the present invention, the direction of the adopted coordinate system is stipulated as follows: the abscissa is positive to the right, and the ordinate is positive downward.
[0079] A kind of driver smoking behavior monitoring method, this method comprises the steps of following order:
[0080] S1. Execute the initialization module. At system startup, load the necessary classifier learning files.
[0081] S11, establishing a face detection classifier;
[0082] S12. Establish a nose detection classifier. Both the face detection classifier and the nose detection classifier adopt the adaboost algorithm.
[0083] S2. Execute the acqui...

The invention relates to a method for monitoring a driver's smoking behavior. The method comprises the following steps: establishing a face detection classifier and a nose detection classifier; collecting the driver's driving state image in real time; The effective detection area of the driver's mouth; judge whether there is a cigarette in the effective detection area of the mouth in the current frame driving state image. The method of the invention has the characteristics of high monitoring accuracy, low false detection rate, fast speed and low 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...
