Abstract

The invention discloses an attention detection method fusing multiple discrimination technologies. The method comprises three stages of human face posture estimation, human face expression analysis and upper body behavior analysis; collected images are subjected to human face posture estimation, human face expression analysis and upper body behavior analysis through a fusion multiple discrimination technology, and then a final attention detection result is obtained in combination with analysis results of the three stages. According to the technology of the invention, no tool is needed, the detection cost is greatly reduced, the economic benefit is improved, and the quantitative analysis of the attention is realized; the attention is divided into four conditions of inattention, attention relative concentration, attention concentration and attention focused concentration according to the quantitative result, and the attention detection accuracy is greatly improved.

Description

technical field

[0001] The invention relates to the technical fields of computer vision and educational informatization, in particular to an attention detection method integrating multiple discrimination technologies. Background technique

[0002] Whether students concentrate in class is an important indicator of learning efficiency and teaching quality. The traditional analysis of students' attention mainly adopts methods such as classroom observation or scale comparison, and there are obvious deficiencies and lags in the aspects of informatization, standardization and intelligence. With the rapid development of information technology, especially computer vision technology, informatization and intelligence have been widely used in various fields of people's daily life. It is possible to deploy information systems in classrooms to observe and record students' behaviors. Automated observation of student attention provides a technical approach.
