Embodiment Construction

[0021] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0022] In the description of the present invention, unless otherwise specified, " / " means "or", for example, A / B may mean A or B. The "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: A exists alone, A and B exist at the same time, and B exists alone These three situations. In addition, "at least one" and "plurality" mean two or more. Words such as "first" and "second" do not limit the number and order of execution, and words such as "first" and "second" do not necessarily limit the difference.

[0023] The teaching quality evaluation method provided by the embodiment of the present invention can be applied to a teaching quality evaluation system. figure 1 A schematic ...

Abstract

The invention discloses a teaching quality evaluation method and electronic equipment, relates to the technical field of image processing, and is used for accurately evaluating the fairness of teaching. The method comprises the following steps: obtaining a first sight direction of a teacher in a first teaching image, wherein the first teaching image is any one of a plurality of teaching images in preset time, and the plurality of teaching images comprise teachers; based on the first sight line direction and a preset three-dimensional space model, determining a sight line drop point corresponding to the first teaching image, wherein the preset three-dimensional space model comprises a three-dimensional coordinate system of the classroom, and the sight falling point corresponding to one teaching image is an intersection point of the sight direction of the teacher on one teaching image and a preset plane in the three-dimensional coordinate system; and determining the number of the plurality of sight falling points corresponding to the plurality of teaching images in different areas of the three-dimensional coordinate system, and evaluating the teaching quality of the teacher based on the determined number and a preset rule. The embodiment of the invention is applied to the teaching quality evaluation system.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a teaching quality evaluation method and electronic equipment. Background technique [0002] With the development of informatization, the means of informatization can be applied to the evaluation of teachers' classroom teaching fairness. Specifically, the teaching quality assessment device acquires multiple teaching images, and determines the teacher's line of sight by analyzing the orientation of the teacher's head in each teaching image. Further, the teaching quality evaluation device evaluates the teacher's degree of attention to different areas in the classroom according to the distribution of the teacher's line of sight in different directions in the classroom in the multiple teaching images. [0003] However, the distribution of the teacher's line of sight in different directions in the above scheme cannot accurately reflect the teacher's attention to different ar...
