Problems solved by technology

Among them, the segmentation method of the specified frame or duration needs to be manually operated and the entire video content needs to be watched in advance. The segmentation method according to the blank gap of the content is likely to cause inaccurate segmentation and make it difficult for viewers to understand

Embodiment 1

[0026] figure 1 It is a flowchart of a video segmentation method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of dividing a video, especially applicable to the situation of dividing a teaching video. The method can be executed by a video segmentation device, and the video segmentation device can be implemented in software and / or hardware, for example, the video segmentation device can be configured in a computer device. like figure 1 As shown, the method includes:

[0027] S110. Acquire the video to be divided, and determine the correspondence between the knowledge point data and the video frames in the video to be divided.

[0028] In this embodiment, the video to be divided may be an educational teaching video, or a popular science video. After obtaining the video to be segmented, analyze the content of the video to be segmented, extract the subtitle content, voice content and / or text content in the video frame of the ...

Embodiment 2

[0037] figure 2 It is a flowchart of a video segmentation method provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the foregoing embodiments. like figure 2 As shown, the method includes:

[0038] S210. Acquire the video to be segmented, input the video to be segmented into a pre-trained video segmentation model, acquire segmented data output by the video segmented model, and determine the interval of video frames corresponding to the knowledge point data according to the segmented data.

[0039] In this embodiment, the video to be segmented is segmented by a machine learning algorithm. Specifically, the video to be segmented is input into the trained video segmentation model, and the segmentation data output by the video segmentation model is obtained. Wherein, the segmentation data output by the video segmentation model may include the knowledge point data contained in the video to be segmented and the corresponding relation...

Embodiment 3

[0051] Figure 3a It is a flow chart of a video segmentation method provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the foregoing embodiments. like Figure 3a As shown, the method includes:

[0052] S310. Acquire the video to be divided, and determine the correspondence between the knowledge point data and the video frames in the video to be divided.

[0053] S320. Segment the video to be segmented according to the corresponding relationship to obtain at least one video segment.

[0054] S330. Determine the association relationship between the video clips according to the association relationship between the knowledge point data, and determine at least one learning path according to the association relationship between the video clips.

[0055] In this embodiment, after the video to be divided is divided, the relationship between the divided video segments is determined according to the relationship between the knowledge poin...

Abstract

The embodiment of the invention discloses a video segmentation method and device, equipment and a medium. The method comprises the steps: obtaining a to-be-segmented video, and determining the corresponding relation between knowledge point data and video frames in the to-be-segmented video; and segmenting the to-be-segmented video according to the corresponding relationship to obtain at least onevideo clip. According to the video segmentation method provided by the embodiment of the invention, the to-be-segmented video is segmented according to the knowledge point data in the to-be-segmentedvideo, so that the segmentation process of the video is simplified, and the segmentation accuracy of the video is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of information processing, and in particular, to a video segmentation method, device, equipment, and medium. Background technique [0002] With the rapid development of mobile Internet technology, video teaching resources have been greatly promoted. Digital teaching videos are favored by teachers and students. The existing teaching videos are relatively long, one lesson corresponds to one video, and one video contains multiple knowledge points. Therefore, if you need to view a certain knowledge point in the video, you need to divide the video. [0003] In the process of implementing the present invention, the inventors found at least the following technical problems in the prior art: the current video segmentation mainly performs video segmentation according to specified frames, duration or content blank gaps. Among them, the segmentation method of the specified frame or duration needs to be m...
