Abstract

The invention relates to an intelligent television user fatigue detection system and method based on face multi-feature fusion. The system is based on intelligent television application and mainly comprises a fatigue detection setting module, a video data acquisition module, a face feature point extraction module, an eye aspect ratio calculation module, a blinking detection module, a head posturedetection module and an intelligent fatigue detection module. The number of blinking times in unit time is determined according to the change of the eye aspect ratio. Through the occurrence of a sleepiness event determined by inclination of the head posture, and the duration of unit time, the fatigue state of the user is judged in a combined mode, an implementation method is provided based on thesystem, comprehensive multi-feature fusion analysis and combined decision making are conducted on fatigue detection multi-dimensional features in a smart television use scene, the accuracy of fatiguerecognition is improved, and the probability of false triggering is reduced.

Description

technical field [0001] The invention relates to the fields of smart TV terminal technology and face recognition, in particular to a smart TV user fatigue detection system and method based on multi-feature fusion of faces. Background technique [0002] With the development of society and the advancement of science and technology, people's living standards are improving day by day. Smart TV has been popularized in thousands of households and has become an important part of people's daily leisure and entertainment, and is very popular with the public. But in life, watching TV for a long time often leads to fatigue, and often falls asleep unconsciously. If the TV continues to play at this time, it will not only waste resources, but also affect the quality of sleep. How to judge The viewer's fatigue state while watching television has become a concern. Contents of the invention [0003] Aiming at the existing problems, the present invention proposes a smart TV user fatigue det...
