Problems solved by technology

As the main carrier of online learning, online course video plays a pivotal role in the development of distance education. However, although online learning is very convenient, compared with face-to-face teaching, the learning method through online video has shortcomings, mainly manifested in the lack of personal experience. Its learning environment, video and courseware production level and demonstration quality are generally not high, relying too much on machines, weakening the communication between teachers and students in the classroom
[0003] Over the years of the development of online education, there are many excellent online course videos on the Internet, but these online course videos are relatively boring and difficult to attract learners to concentrate on watching for a long time

Abstract

The invention relates to a method for converting a video or audio into a VR video. The method comprises the steps that an audio file is acquired, or an audio file in a video is extracted; a subtitle file corresponding to the audio file is acquired through voice recognition; emotion labels of all text sentences in the subtitle file and difference values of timestamps are obtained by means of natural language processing, and the subtitle file is converted into a text file; figures in the video or audio are modeled through a 3D modeling tool to obtain a figure model file; a corresponding animation file is recorded for the emotion label of each text sentence through recording equipment, or a corresponding animation file is made for the emotion label of each text sentence through the 3D modeling tool; and by means of a 3D game engine, voice matching is conducted on the audio file, subtitle matching is conducted on the text file, expression action matching is conducted on the figure model file and the animation files, and a VR video in a three-dimensional scene is generated.

Description

technical field [0001] The present invention relates to the technical field of virtual reality, in particular to a method and device for generating a VR video. Background technique [0002] In recent years, with the development of computer technology and network technology, the trend of network learning has become more and more obvious. Compared with traditional teaching, online teaching has many advantages. It is not limited by time and region, takes students' activities as the teaching center, and makes full use of the advantages of rich online teaching resources. As the main carrier of online learning, online course video plays a pivotal role in the development of distance education. However, although online learning is very convenient, compared with face-to-face teaching, the learning method through online video has shortcomings, mainly manifested in the lack of personal experience. Its learning environment, video and courseware production level and demonstration qualit...
