Embodiment 1

[0053] This embodiment provides a method for storing video summary data, such as figure 1 shown, including the following steps:

[0054] S1: Obtain the summary data of the moving target from the video image data.

[0055] S2: Store the abstract data in a file fragmented manner.

[0056] In the method for storing video abstract data described in this embodiment, the video image data may be real-time video image data or historical video image data. As an optional implementation manner, the above video image data may be acquired from a monitoring platform. In practical applications, it will first judge whether a real-time or historical video image data acquisition request is received. When the request is received, the monitoring platform will transmit the real-time or historical video image data in the form of data packets through the network and send them to the destination After that, the received data packets are framed according to the transmission protocol, and the encode...

Embodiment 2

[0093] This embodiment provides a storage system for video summary data, such as figure 2 shown, including:

[0094] The summary data obtaining module 1 is used for obtaining the summary data of the moving target from the video summary data.

[0095] The slice storage module 2 is configured to store the summary data acquired from the summary data acquisition module 1 by means of file slices.

[0096] As a preferred implementation, the video abstract data storage system described in this embodiment, the fragment storage module 2 further includes:

[0097] The setting unit 21 is configured to set the maximum fragmentation time.

[0098] The fragmentation unit 22 is configured to generate a fragmentation file for storing the obtained summary data when the time for obtaining the summary data reaches the maximum fragmentation time.

[0099] The storage system of the video summary data described in this embodiment stores the summary data of the moving target obtained from the su...

Embodiment 3

[0107] This embodiment provides a display system for video summary data, such as image 3 shown, including:

[0108] A storage module, the storage module has a built-in storage system for video abstract data according to any one of claims 1-13.

[0109] Display module, when there is a request to play the original video, play real-time or historical video image data that meets the search conditions; when there is a request for target retrieval and display, preview and display the best picture of the moving target that matches the search condition; When there is a request for condensed synthesis display, the summary data is subjected to region filtering, line-pass filtering, and filter compression ratio selection processing, and then the condensed synthesis display is performed.

[0110] The intelligent identification module is used for extracting summary data.

[0111] The intelligent management module is used to trigger or close the corresponding functions of the storage mod...

Abstract

The invention provides a storage method and system and a display system for video abstract data. According to the storage method and system for the video abstract data, the abstract data, obtained from video image data, of a moving target are stored in a file fragmentation mode, and a fragmentation file formed by the obtained abstract data can be generated and stored at each maximum fragmentation time. Compared with the single-file storage mode that in the prior art, data storage cannot be carried out until video data transmission is finished, abstracts can be extracted in real time, and the video abstract data can be continuously stored in real time through the storage method and system and the display system for the video abstract data; in addition, due to the real-time characteristic, the time delay from the moment that some moving target appears in a monitoring front-end image to the moment of obtaining the abstract data of the moving target is only the sum of the network image transmission time delay and the abstract data extraction time delay, and the video copying time delay and the video storage time delay are omitted.

Description

technical field [0001] The invention relates to a storage method, system and display system of video summary data. Specifically, it relates to a storage method, system and display system for video summary data based on video surveillance. Background technique [0002] In recent years, with the construction of a safe city, the scope of video surveillance has gradually expanded. Video surveillance technology, with its advantages of being able to directly or indirectly record the criminal process, makes the suspect's image, behavioral characteristics, and property loss and other information intuitive. It can be seen that video surveillance technology has gradually become an important means of collecting criminal evidence and extracting criminal clues in the process of solving various cases. Video image detection technology has become the fourth largest investigation technology for public security organs after criminal technology, mobile technology, and network detection technol...
