Method and system for detecting fatigue driving based on head and neck movement feature recognition of driver

Abstract

The invention discloses a method and a system for detecting fatigue driving based on head and neck movement feature recognition of a driver. The method comprises the following steps: (1) arranging a camera on the side face of a driving position in a car, and collecting images of the head and neck part of the driver from the side face; (2) storing a group of images collected by the camera in the step (1) through an image processing unit at intervals of time T, and abstracting contour lines of head and neck side images of the driver; and (3) forming head and neck movement features of the driver according to a plurality of groups of continuous contour lines of the head and neck side images of the driver, wherein the continuous contour lines of the head and neck side images of the driver are obtained from the step(2), comparing the head and neck movement features of the driver with the head and neck movement features when a human body is in a sleepy state, carrying out judgment, if the head and neck movement features of the driver conform to sleepy state requirements, considering the driver to be fatigue driving and sending an alarm prompt, or else, repeating the step (2), and keeping operation continuously and circularly. The method and the system for detecting fatigue driving based on head and neck movement feature recognition of the driver have the advantages that detecting recognition accuracy is high, the requirements for an image processing algorithm and corresponding hardware are low, and implementation is easy.

Description

technical field [0001] The invention relates to a fatigue driving detection method and system, in particular to a fatigue driving detection method and system based on driver head and neck movement feature recognition. [0002] Background technique [0003] With the continuous increase of the total highway mileage and the number of motor vehicles, and the increase of vehicle speed, road traffic accidents in my country are increasing year by year, and the number of major accidents and casualties is on the rise. It has become a threat to the safety of people's lives and property and the sustainable development of society. Serious Problem. In many traffic accidents, the driver's human factor has become one of the main factors of traffic accidents. Research and analysis by scientists in the United Kingdom and the United States shows that road traffic accidents caused by drivers themselves account for 57% to 65% of the total number of traffic accidents, and accidents caused by fa...
