Abstract

The embodiment of the invention discloses a method for matching exercises with a teaching video. The method is used to solve the problems that the screening difficulty of manual exercise screening is large and the efficiency is low. The method disclosed by the embodiment of the invention comprises the steps that a current teaching material picture in a target teaching video is acquired; character recognition is conducted on a title and / or main body contents in the teaching material picture, so knowledge point keywords are obtained; the knowledge point keywords are matched with each exercise in a preset exercise base, and the exercises of a preset amount with the highest matching degree are taken as target exercises; and corresponding relations between the target exercises and the teaching material picture are established, so the target exercises can be displayed in a preset mode when the teaching material picture is played in the target teaching video. The embodiment of the invention also provides a device for matching the exercises with the teaching video, and a recorded playing system.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a teaching video exercise matching method and device, and a recording and broadcasting system. Background technique [0002] In the field of video teaching, during or after the teacher is teaching the students, a series of exercises are often required to consolidate the students' knowledge points, so as to examine the students' mastery of the knowledge points. [0003] At present, the selection of exercises generally adopts the method of manual preprocessing. The teacher first determines the knowledge points required for this video teaching, and then the teacher manually selects relevant exercises from the question bank based on these knowledge points. When students watch the teaching video, the system Display these exercises preset by the teacher. [0004] However, this method of manual screening of exercises requires the teacher to select exercises corresponding to kn...
