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 based on 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 smart classroom deployment method belongs to the technical field of data processing methods, and comprises the following steps: S1, teacher detection: arranging a camera at a teacher, aligning the camera to a platform, after the camera obtains an image, firstly establishing a background model and searching a moving object, and judging whether the moving object is the teacher according to the body type and skin color range of the teacher; step S2, teacher tracking; s3, correcting by a teacher; s4, action identification: after the teacher enters a preset blackboard area, judging whether the teacher is the back according to the change of the face skin color, and if so, close-up the blackboard picture; when the residence time of the teacher in the area exceeds a threshold value, the residence area is amplified; and when the image change exists in the curtain area, the curtain area is close up. According to the scheme, it is judged that the teacher needs to close up or amplify a specific area according to the position of the teacher, students can clearly see characters on a blackboard or a projection curtain, and demonstration or explanation of the teacher can be conveniently understood.

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 the publication number CN201811081325.1 discloses a smart classroom cloud platform, including a teacher camera. The teacher camer...
