Abstract

The invention relates to a system and a method for recording a teaching video. The system comprises a camera sub-system, a tracking sub-system, a recording sub-system, an editing sub-system. The method comprises the steps of: setting a template; shooting in the whole scene; analyzing a panoramic picture; sending out a command of starting up tracking; tracking; acquiring; triggering; switching; recording; and editing. A recording template and an intelligent triggering and switching device adopted in the invention can remove useless scenes efficiently, edit the teaching video based on a teaching scene language, carry out multiple after-treatments such as automatic color cast adjustment and de-noising by using the editing sub-system, and also can add individual openings and endings, so that automatic edition of the teaching video is realized, and a person without any professional training can edit well. The method for recording the teaching video realizes teacher tracking stability as a safety frame strategy is adopted, removes useless scenes of excessive actions of students by using a student action anti-interference strategy, and avoids redundancy of the teaching video.
