Embodiment Construction

[0058] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0059] A deployment method for a smarter classroom includes the following steps:

[0060] Step S1, teacher detection: after the teacher arranges the camera and points the camera at the podium, after the camera obtains the image, first establishes a background model and searches for a moving object, and judges whether the moving object is a teacher by using the teacher's body shape and skin color range.

[0061] In this step, the camera can automatically detect the teacher who is in a moving state.

[0062] Step S101, first perform grayscale processing on all camera images, thereby reducing the influence of illumination;

[0063] In step S102, the camera image is input to establish a background model; the background model includes the background image and the reference image.

[0064] The reference image is used as a buffer for sudden changes in the camera i...

Abstract

A deployment method for a smarter classroom belongs to the technical field of data processing methods, and includes the following steps: Step S1, teacher detection: when the teacher arranges a camera, points the camera at the podium, and after the camera obtains an image, firstly establishes a background model and searches for a moving Step S2, teacher tracking; Step S3, teacher correction; Step S4, action recognition: when the teacher enters the preset blackboard area, judge whether the moving object is a teacher according to the change of facial skin color The teacher is the back, if it is, it will close up the blackboard screen; when the teacher stays in the area for more than the threshold, the staying area will be enlarged; when there is an image change in the screen area, the screen area will be close-up. In this plan, according to the teacher's position, it is necessary to close up the teacher or zoom in on a specific area, so that students can clearly see the words on the blackboard or projection screen, and it is convenient to understand the teacher's demonstration or explanation.

Description

technical field [0001] The invention belongs to the technical field of data processing methods, and in particular relates to a deployment method of a smart classroom. Background technique [0002] There are two current teaching methods: one is the traditional classroom where teachers teach and students listen to lectures. In this way, the classroom environment and time of each class are easily limited, and the space and time for students to learn are easily limited. [0003] The second way is to learn through the Internet. This way of learning is to record the teaching video for the online teacher or use the live broadcast method for students to learn and watch online. This way of learning is not easily affected by time, space and environment. The number of studies can also be flexible to meet demand. [0004] For example, the Chinese patent with publication number CN201811081325.1 discloses a smart classroom cloud platform, including a teacher camera, which is used to coll...
