Abstract

The invention provides a driver distraction behavior analysis method. The method comprises the steps of S1 when an automobile starts to walk, starting to acquire a face image of a driver through a camera, identifying the face image, judging whether a blinking frequency f of the driver during normal driving is pre-stored or not, if so, directly acquiring the blinking frequency f of the driver, and otherwise, acquiring the blinking frequency f of the driver in unit time through the camera, and storing the blinking frequency f; and S2 obtaining the real-time blinking frequency F of the driver in the driving process through the camera, and when F is smaller than or equal to 1 / 2f, pre-judging that the driver is in the road hypnosis distraction state, and carrying out further recognition.

Description

technical field [0001] The invention relates to a method for analyzing driver's mind-wandering behavior. Background technique [0002] During the driving process of the vehicle, the two behaviors of driver distraction (road hypnosis) and fatigue driving are the culprits most likely to cause danger. Especially on a high-speed highway, even a second of distraction can produce great harmful results. The driver's mind-wandering behavior is often caused by the relatively single road environment; while fatigue driving is often related to the driver. However, there is no relevant report in the prior art that can effectively distinguish mind-wandering behavior from fatigue driving. Contents of the invention [0003] The present invention provides a driver's mind-wandering behavior analysis method, which can effectively solve the above problems. [0004] The present invention is achieved like this: [0005] A method for analyzing driver's mind-wandering behavior, comprising the...
