Abstract

The invention discloses a driver fatigue detection method and system based on computer vision. The method comprises: firstly, a camera is called to collect a driver face video; Then, the face is positioned through an AdaBoost classifier algorithm of the Harr-like feature; then, blinking and yawing detection are carried out by utilizing the Landmark to prompt fatigue; and finally, positioning humaneyes through picture preprocessing, judging fatigue according to a PERCLOS algorithm criterion, and carrying out early warning. According to the method, fatigue early warning is carried out on the driver by combining a PERCLOS human eye detection algorithm and a human face key point extraction algorithm, non-contact performance and real-time performance are achieved, interference on normal driving of the driver is avoided, and fatigue detection is more accurate, more efficient and faster.

Description

technical field [0001] The invention relates to the technical field of image detection, in particular to a computer vision-based driver fatigue detection method and system. Background technique [0002] According to the statistics of the traffic department, the number of deaths due to road traffic accidents has continued to increase in recent years. Fatigue driving of motor vehicle drivers is an important cause of traffic accidents. Many experts and scholars are actively researching methods for detecting fatigue driving. How to effectively prevent fatigue driving has become a domestic research hotspots. [0003] Traditional driver behavior detection algorithms based on physiological signals and behavioral features have their advantages and disadvantages. Among them, the detection algorithm based on physiological signal features has high precision, but because the sensor is in contact with the driver, driving is affected; the detection algorithm based on behavioral features ...
