Abstract

The invention discloses a study monitoring system based on myopic glasses. The study monitoring system based on myopic glasses comprises a study monitoring terminal and a service analysis terminal, wherein the study monitoring terminal and the service analysis terminal are connected through a wireless communication network; the service analysis terminal comprises a data preprocessing module, a screening obtaining module, a feature extraction module, a management server, a feature database and a display module; the data preprocessing module is respectively connected with the screening obtainingmodule and the feature extraction module; and the management server is respectively connected with the screening obtaining module, the feature extraction module, the feature database and the displaymodule. The study monitoring system based on myopic glasses can remind a wearer of a safe distance from the eyes to a desktop so as to protect the eyesight; a sitting posture normalization evaluationcoefficient and a study state conformity coefficient of the wearer in a wearing duration can be evaluated; the sitting posture and the study state of the wearer are intuitively shown; the monitoring management on the study process of the wearer is realized; and the characteristic of high detection accuracy is realized.

Description

technical field

[0001] The invention belongs to the technical field of eye monitoring for learning, and relates to a learning monitoring system based on myopia glasses. Background technique

[0002] With the rapid development of society, the learning tasks of students and office workers are gradually increasing, resulting in excessive eye use, and the number of people wearing myopia glasses is gradually increasing.

[0003] In the prior art, an infrared detector is installed on the glasses to detect the distance between the eyes and the table, so that when the distance between the eyes and the table is less than 30cm, a prompt is given. There is a single function, and at present only by measuring the distance between the eyes and the table. The distance between the desktop can judge whether it is at a safe distance, but it is impossible to judge the sitting posture of the students and the learning status of the students according to the distance between the eyes and the desk...
