Abstract

The invention relates to a fatigue driving warning system on the basis of human face recognition and belongs to the technical field of safety driving warning. The fatigue driving warning system comprises an image acquiring and converting module, an image preprocessing module, a human face detecting module, a face fatigue characteristic extraction and tracking module, a multi-fatigue characteristic integrating module, a fatigue warning module, a data storage module and a power source supply module. The fatigue driving warning system has the advantages that face recognition and fatigue characteristics of a driver are quickly extracted, fatigue characteristics of face are accurately tracked, multiple pieces of fatigue characteristic information of the face are quickly integrated and processed, fatigue states are quickly detected under the conditions of complicated backgrounds and shading of the face of the driver, the fatigue driving warning system has higher robustness to environment changes, and real-time, non-contact, quick and accurate fatigue warning on the basis of the face recognition technology is realized. Besides, the fatigue driving warning system is high in practicality.

Description

technical field [0001] The invention relates to the technical field of safe driving early warning, in particular to the technical field of fatigue driving early warning, in particular to a fatigue driving early warning system based on face recognition. Background technique [0002] Statistical analysis of traffic accidents shows that with the development of the transportation industry and the increase of vehicle speed, traffic accidents have become a serious problem in all countries, and driver fatigue is one of the important reasons for traffic accidents. In order to prevent drivers from driving fatigue, traffic management departments at home and abroad usually educate drivers to remind drivers that when driving fatigue, in order to keep alert, they should stop and rest. However, the prevention of driving fatigue is limited by means of education alone. It is necessary to use scientific means to analyze the mechanism of fatigue, design a set of driving fatigue warning modu...
