Embodiment 1

[0026] figure 1 It is a flowchart of a video retrieval method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of retrieving videos in a database. The method can be executed by a video retrieval device, which can use software and / or or hardware, and the device can be configured in a terminal device. Specifically include the following steps:

[0027] S110. Obtain a search tag input by the user, and determine at least one search video corresponding to the search tag in the video index database based on the search tag;

[0028] Wherein, the retrieval tag is a tag used to retrieve the video, and in one embodiment, the retrieval tag includes at least one element tag. Exemplarily, the search tag includes "object A and object B", wherein both object A and object B are element tags, that is, the search tag includes two element tags. Wherein, the video index library includes element label index information of each retrieved video. Wh...

Embodiment 2

[0043] figure 2 It is a flow chart of a video retrieval method provided in Embodiment 2 of the present invention, and the technical solution of this embodiment is further refined on the basis of the foregoing embodiments. Optionally, before feeding back the video clips to the user, the method further includes: scoring the video clips, and sorting the video clips based on the scoring results.

[0044] The specific implementation steps of this embodiment include:

[0045] S210. Obtain a search tag input by the user, and determine at least one search video corresponding to the search tag in the video index database based on the search tag;

[0046] S220. Divide each retrieved video to obtain at least one video segment according to the element tag index information corresponding to the search tag and a preset division rule;

[0047] S230. Scoring each video segment, and sorting each video segment based on the scoring result;

[0048] In one embodiment, optionally, for each vid...

Embodiment 3

[0061] Figure 4 It is a schematic diagram of a video retrieval device provided in Embodiment 3 of the present invention. This embodiment is applicable to the case of retrieving videos in a database, and the apparatus may be implemented in software and / or hardware, and the apparatus may be configured in a terminal device.

Abstract

The embodiment of the invention discloses a video retrieval method, device and equipment and a storage medium. The method comprises the steps that a retrieval label input by a user is acquired, at least one retrieval video corresponding to the retrieval label is determined in a video index library based on the retrieval label, the retrieval label comprises at least one element label, and the videoindex library comprises element label index information of all the retrieval videos; according to the element label index information corresponding to the retrieval label in each retrieval video anda preset division rule, each retrieval video is divided to obtain at least one video clip, wherein the preset division rule comprises taking a video composed of video frames in which at least one element label continuously appears as a video clip; and each video clip is fed back to the user. According to the embodiment of the invention, the retrieval video is divided according to the retrieval label, so that the problem of inaccurate video retrieval is solved, and the video retrieval efficiency and accuracy are improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of data processing, and in particular, to a video retrieval method, device, device, and storage medium. Background technique [0002] With the enrichment and development of Internet applications, we are exposed to more and more video data. Faced with massive video data at this time, users often need to quickly retrieve video data that meets the query requirements. However, since the video data includes various scenes composed of characters, objects, environments and other features, when we need to query the flexible combination of scenes, there are often hundreds of millions of information analysis results of the video data, and various retrieval The combinations of tags are even more numerous. [0003] Since video data has different lengths and contains various contents, users have different retrieval requirements. When a user retrieves a part of the video content included in the vi...
