Embodiment Construction

[0036] The technical solutions of the present invention will be further specifically described below through specific embodiments and in conjunction with the accompanying drawings.

[0037] A vision-based driving behavior detection method, the processing flow is as follows figure 1 As shown, the cab image is collected, face information is extracted, face detection and identity verification are performed using a deep convolutional neural network, and the position of key points of the face and the feature map of the face are output; the position of the key points of the face and the face Feature map, for fatigue driving application detection and distracted driving application detection; based on the fatigue driving and distracted driving application detection results, judge the driver's fatigue state and distracted state, issue fatigue warning and distraction early warning signals, and warn driving fatigue behavior and Driving distraction behavior, judge and display driving fati...

Abstract

A vision-based driving behavior detection method, including: collecting cab images, extracting face information, using a deep convolutional neural network for face detection and identity verification, and outputting key point positions of faces and face feature maps; Based on the detection results of fatigue driving and distracted driving applications, judge the driver's fatigue state and distracted state, and issue fatigue warning and analysis. God warning signal, warning of driving fatigue behavior and driving distraction behavior, judging and displaying driving fatigue level and driving concentration level. One purpose of the present invention is to improve the driver behavior monitoring system, intelligently analyze the fatigue driving behavior (including drowsiness, yawning, bowing the head) and distracted driving behavior (including answering the phone, smoking) during the driving process, and provide behavior reminders .

Description

technical field [0001] The invention relates to the technical field of safe driving, in particular to a vision-based driving behavior detection method. Background technique [0002] There are 500,000 traffic accidents in China every year, and the death toll due to traffic accidents exceeds 100,000. According to the statistics of road traffic accidents, more than half of the traffic accidents are caused by the driver's danger or wrong vehicle operation. However, most of these man-made accidents are caused by fatigue driving, so the intelligent analysis and early warning system of driving behavior has important application value. The active safety systems of existing passenger cars and commercial vehicles rarely have functions involving driver behavior analysis and reminders, especially for commercial transport vehicles, where long-term and long-distance driving leads to a higher probability of the above-mentioned fatigue driving. Most existing commercial vehicles do not hav...
