Embodiment 1

[0024] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a video positioning method according to an embodiment of the present invention, which may specifically include the following steps:

[0025] Step 101, analyzing the video to be positioned to generate a voiceprint database set.

[0026] It should be noted that the audio and video channels in the video are separated. In this embodiment, the audio channel information can be obtained by analyzing the video to be located. The audio channel information can specifically include information such as time stamps and audio waveforms. The timestamp is usually a sequence of characters that uniquely identifies a certain moment of time. Both the time stamps in the audio channel information and the video channel information correspond to a time reference line, so they can be synchronized. During specific implementation, the voiceprint library set can be obtained by dividing the audio channel information, su...

Embodiment 2

[0035] On the basis of the foregoing embodiments, this embodiment continues to describe the video positioning method.

[0036] refer to figure 2 , which shows a flow chart of the steps of an embodiment of a video positioning method according to an embodiment of the present invention, which may specifically include the following steps:

[0037] Step 201, analyzing the video to be positioned to obtain audio channel information.

[0038] It should be noted that the audio and video channels in the video are separated. In this embodiment, the audio channel information can be obtained by analyzing the video to be located. The audio channel information can specifically include information such as time stamps and audio waveforms. The timestamp is usually a sequence of characters that uniquely identifies a certain moment of time. Both the time stamps in the audio channel information and the video channel information correspond to a time reference line, so they can be synchronized. ...

Embodiment 3

[0056] On the basis of the foregoing embodiments, this embodiment continues to describe the video positioning method for videos with voiceprints.

[0057] refer to image 3 , which shows a flow chart of the steps of an embodiment of a video positioning method according to an embodiment of the present invention, which may specifically include the following steps:

[0058] Step 301, associate the voiceprint library, and initialize the voiceprint set Map (including voiceprint and time information).

[0059] It should be noted that this embodiment is a video positioning method for videos with existing voiceprints. The voiceprint set described in this embodiment is the corresponding video voiceprint set. Search according to the video name, if there is a matching item, use this item as the voiceprint set Map of the video.

[0060] Step 302, acquiring a user's voice instruction.

[0061] The acquisition of the user's voice command described in this embodiment can be achieved in th...

Abstract

The present invention provides a video positioning method and device. The method comprises a step of analyzing a video to be positioned to generate a voiceprint library set, a step of obtaining a user voice command, a step of retrieving the voiceprint library set according to the user voice command to carry out matching processing, and obtaining a positioning time coordinate set, and a step of obtaining the frame picture corresponding to the positioning time coordinate set and displaying the frame picture to be select by a user. Compared with a method of adjusting a progress bar for many times by a user to carry out frame previewing and positioning in the traditional technology, the video positioning method of the invention has the advantages that through voiceprint matching, multiple matched position frame pictures are directly displayed, the user can select directly, video positioning steps are simplified, the time of video positioning is saved, thus the video positioning efficiency is improved, and the process of constantly adjusting the progress bar to carry out previewing and positioning by the user is optimized.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a video positioning method and device. Background technique [0002] At present, watching videos has become a necessity in people's daily life, and there are more and more demands for sharing videos and pictures. How to more conveniently locate the video to the location that the user wants or directly obtain the video and picture that the user wants to share is still unknown. Great way. [0003] At present, the main method of video positioning is the method of frame preview and user selection. In this way, users generally need to adjust the progress bar multiple times for frame preview to select. Video positioning takes a long time, the positioning efficiency is not high, the operation is cumbersome, and the user experience is poor. Contents of the invention [0004] The invention provides a video positioning method and device to solve the problem of low video p...
