Abstract

The invention discloses a driver inattentive driving detection method and a driver inattentive driving detection system based on video face analysis. The driver inattentive driving detection method comprises the steps of: acquiring a video sequence of the head of a driver during the driving process; performing face detection on the video sequence to obtain a face image; performing feature positioning on the face image; mapping the positioned face features onto a three-dimensional model to obtain face attitude data of the driver; extracting mouth feature point information from the positioned face features, so as to obtain mouth shape data of the driver; and judging whether the driver drives inattentively according to the face attitude data and the mouth shape data of the driver. The driverinattentive driving detection method and the driver inattentive driving detection system can improve the reliability and precision of judging non-fatigue driving of the driver in various complicated scenes such as at night, having uneven illumination, wearing sunglasses and the like.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a method and system for detecting inattentive driving of a driver based on video face analysis. Background technique [0002] Fatigue driving was once considered to be the most important cause of road traffic accidents, but statistics show that the proportion of accidents caused by inattentive driving (such as driving with a mobile phone, talking for a long time) is higher than that of fatigue driving. On the other hand, fatigue driving can also be classified as inattentive driving. In this way, the development of a high-performance driver inattentive driving detection system can greatly reduce traffic accidents caused by inattentive driving by monitoring the driver in real time and giving appropriate warnings. Existing video-based driver fatigue detection methods and systems are all based on face detection and eye pupil determination, and determine whether the driver i...
