Problems solved by technology

[0005] To sum up, every time the intelligent video analysis server in the existing intelligent video analysis system receives the target information input from the outside, it will decode all the video data related to the target information stored in the first memory , analysis and alarm judgment, for applications where the amount of video data corresponding to the target information to be tested is huge, the external input of the target information to be tested is frequent, and there are various types of targets to be tested, the intelligent video analysis system in the existing intelligent video analysis system The analysis server consumes too many computing resources, takes too long, and has low efficiency, which cannot meet the needs of actual applications

Embodiment 1

[0067] The preprocessing server 20 of the first embodiment includes: an image processing unit 201 and an IVS processing unit 202 .

[0068] The image processing unit 201 decodes the received video data or each frame of video data stored in one or more first memories 21 , and outputs the decoded images to the IVS processing unit 202 . Wherein, the video data in the first memory 201 is stored by frame, or the video data output from the front-end image acquisition device in the form of video frames, the image processing unit 201 outputs the decoded image to the IVS processing unit 202 At the same time, the frame number corresponding to the image is output to the IVS processing unit 202 .

[0069] The IVS processing unit 202 uses the IVS algorithm to separate the target image and the background image contained in each frame of the received image, calculates and obtains the target coordinates and assigns the target ID according to the target image and the background image, and acco...

Embodiment 2

[0075] In the intelligent video analysis system of Embodiment 2, the metadata is stored by the target ID in the second memory 32, and the target position information contained in the metadata is the target track; the target track also carries the image of the data frame of the generated track collection time.

[0076] The preprocessing server 30 of the second embodiment includes: an image processing unit 201 , an IVS processing unit 202 and a track generating unit 303 . Compared with the first embodiment, the preprocessing server 30 in the second embodiment only adds a trajectory generation unit 303. Correspondingly, the IVS processing unit 202 in the second embodiment outputs the frame number, target ID and target coordinates to the trajectory generation unit 303.

[0077] Trajectory generation unit 303 extracts a plurality of target coordinates with the same target ID and continuous frame numbers in the first time according to the frame number and target ID corresponding to...

Abstract

The invention provides an intelligent video analysis system, wherein any first memory in a plurality of first memories included in the system is used for storing video data; a second memory is used for storing metadata; any pre-processing server decodes the received video data or video data stored by the first memory, extracts a target image from the decoded image by utilizing an intelligent video analysis (IVC) algorithm, obtains a target ID (identification) and target position information, stores the target ID and the target position information as the metadata into the second memory; and any retrieving server looks up the metadata matched with a retrieving condition from the second memory according to the retrieving condition input from the external part, and generates and outputs alarm information according to the preset alarming algorithm when judging the metadata accords with the alarming condition. The invention also provides an intelligent video analysis method. With the adoption of the system and method disclosed by the invention, the processing speed of the video data is accelerated, the time is saved and the work efficiency is also improved.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to an intelligent video analysis system and method. Background technique [0002] Intelligent Video Analysis (Intelligent Video System, IVS) is a computer image vision analysis technology that analyzes and tracks the target to be analyzed corresponding to the target image that appears in the scene corresponding to the background image by separating the background image and the target image in the scene. When the intelligent video analysis technology is applied to the video surveillance system, according to the preset alarm algorithm for the scene corresponding to the background image, the target to be analyzed corresponding to the target image in the scene meets the alarm conditions included in the alarm algorithm , the system will generate and output an alarm message. [0003] figure 1 It is a structural schematic diagram of an existing intelligent video analysis system. Combine ...
