Abstract

The invention provides a fatigue detection method. The fatigue detection method includes: continuously acquiring face images of a personnel, and extracting characteristic point information of eyes and the mouth; respectively calculating closing proportions of the right eye and the left eye and the opening time of the mouth; and determining whether the calculated closing proportions of the right eye and the left eye are greater than a preset closing proportion threshold and determining whether the calculated opening time of the mouth is greater than a preset opening time threshold, determining the fact that the personnel is not in a fatigue state if the closing proportions of the right eye and the left eye and the opening time of the mouth are both not greater than the corresponding closing proportion threshold and the opening time threshold, and determining the fact that the personnel is in a fatigue state if one or more of the closing proportions of the right eye and the left eye and the opening time of the mouth is greater than the corresponding closing proportion threshold and the opening time threshold. According to the fatigue detection method, analysis factors are comprehensive, and the identification accuracy is high.

Description

technical field [0001] The invention relates to the field of state detection, in particular to a fatigue detection method and a fatigue detection system using the method. Background technique [0002] Modern fast-paced life combined with long hours of work often induces people to be in a state of fatigue. When people are in a state of fatigue, their reactions become sluggish and their body control ability is reduced. In a specific environment, such as fatigue driving, the driver will appear restless, inattention, etc., unable to accurately judge and quickly deal with various abnormal situations, and even cause traffic accidents in severe cases. Contents of the invention [0003] In view of this, it is necessary to provide a fatigue detection method and a fatigue detection system using the method. [0004] The present invention provides a fatigue detection method, the fatigue detection method comprising: [0005] Continuously collect face images of people, extract featur...
