Embodiment Construction

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the specific embodiments will be described in detail below in conjunction with the accompanying drawings.

[0038] figure 1 This is a flowchart of the steps of the method provided by the embodiment of the present invention. As shown in the figure, the surveillance video image retrieval method of the embodiment of the present invention includes the following steps:

[0039] Step 101: For each frame of pictures captured by the surveillance camera, calculate motion parameters representing the motion information recorded in the frame of pictures;

[0040] Step 102: Add the motion parameter of each frame to the coded data of the frame;

[0041] Step 103: In the retrieval process, extract the motion parameters in the encoded data, and decode only the encoded data whose motion parameters exceed a predetermined threshold.

[0042] The step 101 specifically includes: obtaining ...

Abstract

The invention provides a retrieval method, a device and a monitoring system for monitoring video images, wherein, the retrieval method comprises that: with regard to per frame picture photographed by a surveillance camera, a motion parameter representing the motion information recorded in the frame picture is calculated; the motion parameter of the frame picture is added into the coded data of each frame picture; and in a retrieval process, the motion parameter of the coded data is extracted, and only the coded data which has a motion parameter exceeding predetermined threshold are decoded. The method, the device and the system of the invention can quickly retrieve the pictures with motion information by adding the motion parameter representing the motion information into the coded data of each frame picture.

Description

Technical field [0001] The present invention relates to image processing technology, in particular to a retrieval method, device and monitoring system for monitoring video images. Background technique [0002] The main function of the video surveillance system is to monitor various scenes. It enables managers to observe the situation of all important locations in the control room, such as installing cameras in important places such as entrances and exits, main passages, garages, etc., and transmitting the situation of the monitoring area to the management center in real time as images, and the on-duty personnel through the TV wall You can know the situation of these important places at any time. [0003] The currently commonly used surveillance systems mainly include a camera part and a monitoring part. The camera part is generally installed on site, and it includes cameras, lenses, protective covers, brackets and pan-tilts. Its function is to take a picture of the surveillance ...
