Embodiment 1

[0046] This embodiment provides an intelligent video teaching method for realizing action recognition, such as figure 1 shown, including the following steps:

[0047] Step 1. Obtain the color image of the learner's face, use the face recognition algorithm to search for the learner in the face database, if the learner is found in the face database, obtain the user ID of the learner, and obtain the learner in the system database Historical learning information (including name, gender, age, learning time, learning points, learning progress, learning efficiency, etc.), and uploaded to the display interface, and presented. At this time, the display interface displays a color image of the learner's face, and displays Learners' historical learning information, including basic information such as name, age, and last learning time, can be presented on computer monitors, large screens, projection displays, etc.; otherwise, add the learner's face image to the face database, And add the ...

Embodiment 2

[0112] The present embodiment provides an intelligent video teaching system for realizing action recognition, which specifically includes the following modules:

[0113] A historical learning information acquisition module, which is configured to: acquire the historical learning information of the learner;

[0114] A learning video playing module, which is configured to: acquire and play learning videos based on learners' historical learning information;

[0115] Among them, in the process of playing the learning video, based on the state judgment cycle, the learner’s face color image is obtained, the key points of the face in the face color image are identified, and the average value of the left and right eye closure and mouth are calculated based on the key points of the face Opening angle, based on the average of left and right eye closure and mouth opening angle to determine whether the learner is in a state of fatigue; at the same time, capture the key points of the learn...

Embodiment 3

[0118] This embodiment provides a computer-readable storage medium, on which a computer program is stored. When the program is executed by a processor, the steps in the intelligent video teaching method for realizing action recognition as described in the first embodiment above are implemented.

Abstract

The invention provides an intelligent video teaching method and system for realizing action recognition. The method comprises the following steps: acquiring historical learning information of a learner; acquiring and playing a learning video based on the historical learning information of the learner; wherein in the process of playing the learning video, the positions of the body joint points of the learner are obtained in real time, the body movement of the learner is judged, and the playing progress of the learning video is controlled based on the body movement of the learner; meanwhile, acquiring a face color image of the learner, recognizing face key points in the face color image based on the face color image of the learner, calculating a left and right eye closure degree mean value and a mouth opening angle based on the face key points, calculating a head turning angle based on the face color image, and calculating the head turning angle based on the left and right eye closure degree mean value, the mouth opening angle and the head turning angle. And updating the video playing content. The limb control of the playing progress and the autonomous updating of the playing content in the online education are realized.

Description

technical field [0001] The invention belongs to the technical field of intelligent video teaching, and in particular relates to an intelligent video teaching method and system for realizing action recognition. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In the era of knowledge economy, people's demand for fast learning and mastering new knowledge is increasing day by day.
