Embodiment 1

[0026] figure 1 It is a flow chart of the object deduplication method provided by Embodiment 1 of the present invention. This embodiment can be applied to the situation of analyzing video streams, for example, it is applied to the situation of querying valuable video clips from surveillance videos. This method can be used by the target The deduplication device may be implemented by means of software and / or hardware, and may be integrated on electronic equipment, for example, on a server or computer equipment.

[0027] Such as figure 1 As shown, the target deduplication method specifically includes:

[0028] S101. Acquire any two temporally adjacent first slice video and second slice video.

[0029] Wherein, there is a pre-marked first marked time period at the end of the first slice video, and a pre-marked second marked time period at the beginning of the second slice video, and the first marked time period and the second marked time period overlap . Exemplarily, the first...

Embodiment 2

[0054] Figure 2a It is a schematic flow chart of the target deduplication method in the embodiment of this application. This embodiment is optimized on the basis of the above embodiments. See Figure 2a , the method specifically includes:

[0055] S201. Obtain a video to be divided.

[0056] Exemplarily, a 1-hour surveillance video (for example, 10:00-11:00) is used as the video to be divided. According to the picture of the live video surveillance, set the time to normally track a target as n seconds, and overlap according to n seconds, that is, it is necessary to ensure that the overlapping duration of any two slices in adjacent time series after segmentation is n seconds, where , The value of n can be adjusted according to different monitoring sites. It should be noted here that setting the time for normally tracking a target as the overlapping duration can ensure that a target can be completely tracked within the overlapping time period.

[0057] S202. Determine the n...

Embodiment 3

[0075] image 3 is a schematic structural view of the target weight removal device in Embodiment 3 of the present invention, such as image 3 As shown, the device includes:

[0076] The first acquiring module 301 is configured to acquire any two temporally adjacent first slice video and second slice video, wherein there is a pre-marked first calibration time period at the end of the first slice video, so There is a pre-marked second marked time period at the beginning of the second slice video, and the first marked time period overlaps with the second marked time period;

[0077] The calibration processing module 302 is configured to perform target detection and target tracking on the sub-slice video recordings in the first calibration time period and the sub-slice video recordings in the second calibration time period, and perform target detection and target tracking according to the target detection results and target tracking results. performing target calibration process...

Abstract

The embodiment of the invention discloses a target deduplication method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a first slice video and a second slice video which are adjacent in any time sequence, wherein the end of the first slice video has a pre-marked first calibration time period, a pre-marked second calibration time period exists at the beginning of the second slice video, and the first calibration time period and the second calibration time period are overlapped; respectively carrying out target detection and target tracking on the sub-slice video in the first calibration time period and the sub-slice video in the second calibration time period, and carrying out target calibration processing according to a target detection result and a tracking result to obtain a first calibration result and a second calibration result; and according to the first calibration result and the second calibration result, performing target deduplication processing on the first slice video and the second slice video. Therefore, the effect of target deduplication between different slice videos is realized, and the finally obtained target is ensured to be optimal.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of monitoring, and in particular, to a method, device, electronic equipment, and storage medium for deduplication of objects. Background technique [0002] There are three main types of existing video stream analysis: live, video and offline video files. When performing intelligent analysis on video and offline video files, in order to improve the analysis speed, the video or video files will be sliced, and then scheduled to different Distributed computing in computing units. [0003] At present, the method of dividing the video according to time is often used to slice the video, and then analyze the video of each slice. However, this method has certain shortcomings: there are repeated targets in the analysis results of different slices of video, and the smaller the slice granularity, the more repeated targets obtained in the analysis. Contents of the invention [0004] Embodime...
