Problems solved by technology

[0004] It can be seen that although this solution is intelligent, in the production process, editors still need to use the selection and editing module to select event segments based on statistical analysis results and feature labels, and drag and drop the time segments corresponding to event segments to the timeline to complete Event editing has not achieved completely unmanned operation, and the entire event data needs to be obtained during the processing process, the cost of network broadband and server resource consumption are high

Embodiment 1

[0073] combine figure 1 , 2 As shown, this embodiment provides a method for structuring an event video, which at least includes the following steps:

[0074] S1. Obtain N video frames in the video stream of the event to be processed and a display time stamp corresponding to each video frame.

[0075] Before step S1, it also includes:

[0076] S01. Determine whether the video stream of the event to be processed is a live video stream or a historical video stream according to the game schedule data obtained in advance before the start of the game, and issue a frame drawing task for the video of the to-be-processed event.

[0077] When performing video processing of sports events, especially in the case of football events, the event analysis platform obtains the schedule data in advance before the game starts, and determines whether the video stream of the event to be processed is a live video stream or a historical video stream according to the schedule data.

[0078] Before ...

Embodiment 2

[0158] In order to implement a method for structuring a video of an event in the first embodiment, this embodiment provides a corresponding device 100 for structuring a video of an event, such as: Figure 5 As shown, the device 100 includes at least:

[0159] The acquisition module 1 is used to acquire N video frames in the video stream of the to-be-processed event and the display timestamp corresponding to each video frame;

[0160] The first time axis matching module 2 is used to identify the event time stamp in each video frame of the N video frames, and perform the first time axis matching between the event time stamp and the display time stamp to locate a valid event video;

[0161] The second time axis matching module 3 is configured to parse the event data corresponding to the to-be-processed event video stream to obtain structured data of all events, the structured data includes the occurrence time of the event in the event, and The second time axis matching is perfo...

Embodiment 3

[0177] Corresponding to the above method and device, Embodiment 3 of the present application provides a computer system, including:

[0178] one or more processors; and

[0179] A memory associated with the one or more processors, the memory is used to store program instructions, and the program instructions, when read and executed by the one or more processors, perform the following operations:

[0180] Obtain N video frames in the video stream of the to-be-processed event and the display timestamp corresponding to each video frame;

[0181] Identifying the event time stamp in each video frame in the N video frames, and performing the first time axis matching on the event time stamp and the display timestamp to locate a valid event video;

[0182] Analyze the event data corresponding to the event video stream to be processed to obtain structured data of all events, the structured data includes the occurrence time of the event in the event, and compare the occurrence time wit...

Abstract

The invention discloses a method, device and system for structuring event video. The method at least includes the following steps: obtaining N video frames of the event video stream to be processed, identifying the event time identifier in the video frame, and performing the first step with the display time stamp. A time axis match, and then analyze and obtain the event and perform a second time axis match on the occurrence time of the event in the event and the display timestamp, and determine the starting point and display timestamp and end point of the target event based on several associated events that constitute the target time Display the timestamp, and finally extract the video frame of the target event and edit and compress it into the target video. This method can use two time axis alignments and deep learning algorithms to realize automatic editing of batch event videos, effectively improving the timeliness and accuracy of video editing. Realize that there is no need to pull all the video streams to be processed, and only extract a few relevant video frames for processing, reducing network bandwidth costs and server resource consumption, and reducing costs.

Description

technical field [0001] The present invention relates to the field of video processing, in particular to a method, device and system for structuring event video. Background technique [0002] In the operation of copyrighted events, traditional media will edit some event clips for important events in the process of live broadcast of events or historical video on demand, such as goals, fouls and other events in football matches. The clipped event clips are used for users to browse and share. . Existing practices often rely on hand-editing production by a large number of editors. The timeliness is poor. As far as live events are concerned, the video of an event is often delayed by several minutes or even ten minutes before the event occurs, which affects the user's viewing experience. The content output is low, limited by operating resources, and content production can only be Focus on ensuring key events, the content output of non-head events is particularly affected, and the...
