Abstract

The invention relates to a video teaching course intelligent generation method and system based on deep learning, and the method comprises the steps: recording a preliminary video course for teaching of a lecturer through an intelligent terminal and an optical screen, the intelligent terminal is used for playing a course lecture, and the optical screen is used for carrying out the amplification projection of the course lecture; the optical screen is also used for receiving blackboard writing content written by a lecturer; based on deep learning, performing mask extraction on portrait information in the preliminary video course to obtain a lecturer portrait; based on deep learning, performing mask extraction on projection information in the preliminary video course to obtain blackboard writing content; synthesizing the blackboard-writing content and the course lectures to obtain a target lecture blackboard-writing; according to the method, the teacher portrait and the target lecture blackboard-writing are fused into the preset background, and the target video teaching course is generated, so that recording of high-quality teaching videos can be completed at home, the recording is not limited by a specific site any more, a certain recording cost is saved, and recording of the teaching videos by the teacher is effectively facilitated.

Description

technical field [0001] The invention belongs to the technical field of intelligent video teaching, and in particular relates to a method and system for intelligently generating video teaching courses based on deep learning. Background technique [0002] A large number of teaching courses have been converted to online, and the demand for video courses has exploded. Paradoxically, high-quality video courses often require professional studio recording. Since video courses often have strict requirements on the background of recording and writing on the blackboard, if a studio is not used for recording, a large number of post-processing requirements will be generated, which will not only cost a lot, but also make it difficult and safety risks for lecturers to use the studio due to the isolation of the epidemic. very high. [0003] Therefore, how to provide a simple intelligent system that can help lecturers to complete high-quality video course recording at home has become a te...
