Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0037] refer to figure 1 , an event-based video enrichment method, comprising the following steps;

[0038] S1. Obtain code stream data; code stream data includes low-resolution video, high-definition images with intervals of several seconds, and high-definition moving target images;

[0039] S2, code stream data is transmitted to the buffer for temporary storage;

[0040] S3, event filtering, used for basic filtering of events; the steps of event filtering are;

[0041] The first step is to extract events from the buffer pool;

[0042] The second step is to set up the event filtering form, which has multiple event entries, which is used for the basic filtering re...

Abstract

The present invention relates to the technical field of smart cameras, in particular to an event-based video concentration method, comprising the following steps: S1, acquiring code stream data; S2, transmitting the code stream data to a buffer for temporary storage; S3, event filtering, S4 , extracting the GOP, S5, judging whether the GOP enters the key interval segment; S6, inserting the key interval segment rate mark or the non-key interval segment rate mark; S7, counting, the key interval segment rate mark and the non-key interval segment rate mark are carried out one by one Superimposing and recording; S8, extracting key frames, S9, backing up key frames; S10, lossless output. The invention sequentially filters events, extracts key intervals and extracts key frames, and realizes that each frame of video data in the key intervals will be played without loss, so that the traffic transmission of video data can be reduced, and the video frequency can be improved. The extremely fast experience of playback will not skip the playback of key data, which is more suitable for extensive promotion.

Description

technical field [0001] The invention relates to the technical field of smart cameras, in particular to an event-based video concentration method. Background technique [0002] With the popularization of smart cameras in more and more families, people have higher playback and review requirements for historical video images recorded by cameras, such as wanting to quickly preview key video data captured by cameras in the past day or a few days (event), the normal frame-by-frame playback obviously cannot meet the user's requirements. At this time, a technical means is needed to give the user a quick preview of the historical picture without skipping the playback of key data. Contents of the invention [0003] The purpose of the present invention is to solve the problem existing in the prior art that it is impossible to quickly preview historical pictures of video data without skipping the playback of key data, and proposes an event-based video enrichment method. [0004] In o...
