A method for generating auxiliary statistical report based on audio and video of teaching for young school age

Abstract

The invention discloses an auxiliary statistical report generation method based on teaching audio and video for low school age. The audio and video auxiliary statistics report comes from the extraction and processing of the teaching video resources of special teachers at the present stage. By separating the audio data and video data from a large number of excellent teachers' teaching images, the audio data is collected using the LSTM-based network model. The audio data is converted into text data, and the text data is segmented to generate brief teaching plans through Chinese word segmentation; the video data is first classified through the scene, and then the category and time of the teaching aids appearing in the video are counted through the target detection algorithm based on deep learning, and generated Visualization charts. Finally, the information extracted from the audio data and video data is fused to generate a teaching auxiliary statistical report, which is used for auxiliary teaching of low-school students; the teaching auxiliary statistical report generation system can provide a real-time online teaching auxiliary statistical report, reducing teachers' lesson preparation time.

Description

technical field [0001] The invention relates to the field of teaching aids, and mainly relates to the fields of computer vision and natural language processing in terms of video and audio. Background technique [0002] In general teaching activities, when teachers are dealing with students of low school age, many explanations of abstract knowledge need to be visualized and concretized in order to be easier for students to understand. Therefore, when preparing lessons, teachers must not only prepare their own teaching plans , but also to prepare auxiliary props during class. In this way, the teacher needs to prepare more comprehensive materials to deal with the lecture. Watching a large number of online video course resources of special teachers is a good way to prepare, but if you want to watch a lot The lecture video must consume a lot of lesson preparation time, so saving lesson preparation time and improving efficiency is the key. The teaching auxiliary report is proposed...

AI Technical Summary

Problems solved by technology

[0003] To sum up, we present to the teachers a written report combining pictures and texts on the lecture content of special teachers, which can be used as a reference for the teachers to pay attention to what should be paid attention to in the teaching process when dealing with students of low school age, and greatly shorten the lesson preparation. time, but the form and means to generate such teaching aid reports are not available in the existing technology
