Abstract

The present application provides a scene recognition method and device, which belong to the field of computer technology, and the method includes: acquiring a target video to be recognized; using a preset audio processing algorithm, audio data of the target video, and the audio data In the corresponding playback time stamp in the target video, determine the corresponding relationship between the sound state and the playback time stamp, wherein the sound state includes a sound state and a silent state; according to the corresponding relationship between the sound state and the playback time stamp, determine The corresponding sound state is the playing time stamp of the sound state, and the scene corresponding to the determined playing time stamp is determined as the target scene, so as to establish a corresponding relationship between the scene and the playing time stamp. By adopting the application, the video display effect can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a scene recognition method and device. Background technique [0002] The recording and broadcasting system has functions such as live video, video on demand, and video editing. The server of the recording and broadcasting system can use the video recorder set at the preset position to shoot the target activity to obtain a video file including the activity scene, and then the server can store the video file locally. Thus, the user can obtain the video file in the server through the client, and then perform video on demand. For example, the server can use the video recorder to record the lecture process of the teacher in the classroom to obtain a video file containing the teaching scene, and the user can obtain the video file through the client to realize the teaching recording and broadcasting. [0003] However, the teaching scene not only includes the scene of ...
