Problems solved by technology

Usually special image acquisition equipment and control systems are required, such as special cameras or camera arrays, special identification cards, high-performance computers, special software, etc. The effect of classroom interaction is good, but high hardware costs and transformation costs are required. At the same time, artificial markers The development of design and display models requires professional skills and special operations, which increases the workload of teachers and the difficulty of training
[0005] The existing classroom teaching system based on speech recognition uses voiceprint recognition technology to recognize the teacher's voice instructions and sends the instructions to the projector to realize operations such as voice-activated page turning and voice-activated jump during multimedia playback; only It can be realized by a conventional camera, the principle is simple, and the application is convenient, but it can only realize the interactive function similar to a laser pointer, and the interactive method of classroom teaching has not changed significantly

Embodiment 1

[0057] see figure 1 The intelligent system for assisting classroom teaching provided by the present invention, when used in classroom teaching, in addition to the basic configurations of multimedia classrooms such as projector 1, projection screen 6, and podium 5, also includes a smart camera 4, and projector 1 is fixed on On the ceiling; the smart camera 4 is installed on the lower surface of the projector 1 through the connecting bracket 3, the projection screen 6 is placed on the projection light path of the projector 1, and the projection screen 6 is installed on the platform 5 wall, and the smart camera 4 passes the dedicated data The line 2 is connected with the projector 1 to realize the transmission of data information, and the data packet information is displayed on the projection screen 6 .

[0058] Specifically, one end of the connecting bracket 3 is fixed on the center of the lower surface of the projector 1 by adsorption, and the other end of the connecting bracke...

Embodiment 2

[0071] The intelligent system 4 provided by the present invention for assisting classroom teaching includes a camera housing, a lens module, an imaging module, a computing module, and an interface module, which can directly complete image acquisition and image processing functions. During implementation, the smart camera 4 uses the computing module Integrated into the camera, after the smart camera completes the image acquisition, it will directly process the image, and only send the calculation result to the projector, without transmitting the original image to an external computing unit, such as a computer, and then the external computing unit will calculate the result Transmission to the projector greatly reduces the pressure of data transmission, and also saves the time of data transmission, improves the efficiency of the whole system, makes the response of the whole system more sensitive, and the image processing is based on the embedded platform, and the development langua...

Embodiment 3

[0073] see figure 2 , the artificial interaction method based on the auxiliary classroom teaching intelligent system provided by the present invention, its working steps are:

[0074] 1) Establish a teacher face image, teacher gesture recognition and teacher movement tracking database;

[0075] 2) Image acquisition: the teacher's face is collected through the lens module and the imaging module, and the teacher's face image is obtained;

[0076] 3) Teacher's identity check: step 2) the collected teacher's face image and step 1) teacher's face image in the database are checked and analyzed, thereby determining the teacher's identity;

[0077] If the verification is successful, proceed to step 4);

[0078] If the verification fails, exit;

[0079] 4) After the identity verification is successful, the classroom teaching process is carried out through human-computer interaction, and the human-computer interaction information is projected and displayed.

[0080] When the intell...

Abstract

The invention belongs to the technical field of teaching equipment, and relates to a human-computer interaction method based on a classroom auxiliary teaching intelligent system. The human-computer interaction method comprises the following steps: 1) establishing an information database for teacher face images, teacher gesture recognition and teacher motion tracking; 2) performing image acquisition on the teacher's face to obtain a teacher's face image; 3) checking and analyzing the teacher face image acquired in the step 2) and the teacher face image in the database in the step 1) to determine the teacher identity; if the checking is successful, executing the step 4); if the check fails, performing exiting; 4) after the identity is successfully checked, performing a classroom teaching process through man-machine interaction, and projecting and displaying man-machine interaction information, wherein the man-machine interaction comprises teacher gesture recognition man-machine interaction and teacher motion tracking man-machine interaction. The multimedia courseware is controlled through gestures or limb actions, the method is convenient to use and capable of remarkably improving the classroom interaction effect.

Description

technical field [0001] The invention belongs to the technical field of teaching equipment, and relates to a human-computer interaction method based on an intelligent classroom auxiliary teaching system. Background technique [0002] With the development of artificial intelligence, the use of artificial intelligence technology to empower traditional industries has attracted more and more attention. In the field of education and teaching, attendance management based on face recognition and smart classrooms based on augmented reality are in the ascendant. [0003] The existing classroom teaching is generally a multimedia classroom. The teacher will display the prepared multimedia courseware on the projection screen in front of the classroom through a projector, and operate and interact with a mouse or a laser pointer. [0004] The existing classroom teaching system based on augmented reality technology uses pre-designed artificial markers, such as cards, models, etc., collects ...
