Embodiment 1

[0048] Such as figure 1 As shown, a kind of concentration evaluation method that the embodiment of the present invention provides, comprises:

[0049] Step 101: Acquiring brainwave signals and face images corresponding to the brainwave signals in real time;

[0050] In the embodiment of the present invention, through biological research, it can be known that the factor that really determines the degree of concentration of a person's attention (abbreviation: degree of concentration) is the human brain, that is to say, whether a person's attention is focused or not depends on the brain wave signal. The changes are particularly evident. Therefore, using brain wave signal detection equipment to obtain the tester's brain wave signal as a supervision quantity, so that there is an objective measure of concentration, and using computer vision technology to obtain the tester's face image corresponding to the brain wave signal in real time as Pre-measurement can avoid the interference...

Embodiment 2

[0084] The present invention also provides a kind of specific implementation of the attention concentration evaluation system, because the attention concentration evaluation system provided by the present invention corresponds to the specific implementation of the aforementioned attention concentration evaluation method, the attention concentration evaluation system The purpose of the present invention can be realized by performing the process steps in the specific implementation of the above method, so the explanations in the specific implementation of the above-mentioned attention concentration evaluation method are also applicable to the specific implementation of the attention concentration evaluation system provided by the present invention. Embodiments will not be repeated in the following specific embodiments of the present invention.

Abstract

The present invention provides a method and system for evaluating concentration degree, which can not only avoid the interference of subjective factors on the concentration degree evaluation, but also improve the reliability of the concentration degree evaluation result. The method includes: acquiring brain wave signals and face images corresponding to the brain wave signals in real time; determining the category of the brain wave concentration level corresponding to the brain wave signal, and according to the brain wave signal corresponding to the brain wave concentration level The category identifies the concentration category corresponding to the human face image corresponding to the brain wave signal in real time; the attention concentration classifier is trained according to the human face image and the concentration category corresponding to the human face image. The invention is applicable to the technical field of computer vision.

Description

technical field [0001] The present invention relates to the technical field of computer vision, in particular to a method and system for evaluating the concentration of attention. Background technique [0002] In recent years, with the development of the field of computer vision and the development and deepening of brain wave signals, there are more and more opportunities for the combination of the two. There are also more and more applications for judging the concentration of the testee by facial recognition. However, in many existing studies on concentration of attention, the evaluation results of the concentration of attention of the subjects often have more or less subjective factors of the researchers. [0003] Attention can be said to be the quantitative result of information such as alertness, fatigue, and sensitivity. Nowadays, the general society pays more and more attention to driving safety. Many research institutes are using machine vision to analyze the driver...
