Intelligent target detail capturing device and method in video monitoring system

Abstract

The invention relates to an intelligent target details acquisition device of video monitoring systems and the method thereof. The device uses one or a plurality of fixed cameras to monitor the whole monitored area, and uses one movable camera to capture target details in the set region. First of all, the invention obtains moving targets in the region from the images captured by the fixed cameras through a processing module; then tracks the separated moving targets and determines the motion state; if any target enters the set region, then according to the preset position parameters and focal length parameters of the region, the invention will adjust the direction and the focal length of the movable camera to capture detailed images of the target in the region; at the same time, the invention can conduct storage and remote transmission of the images as required. The invention has the advantages that the invention provides the video monitoring device which not only can monitor a large area, but also can automatically capture details of physical targets, and the method thereof, solving the contradiction between the monitored scope and the monitored target details in the prior art.

Description

technical field [0001] The invention belongs to the technical field of video monitoring, and relates to a device and method for capturing intelligent target details in a video monitoring system. Background technique [0002] At present, in the field of video surveillance technology, most video surveillance videos can only record the motion state of the target in the surveillance scene, but cannot provide clear target detail information. Like this, make the use value of video recording greatly reduce. At present, there are two main methods to improve the definition of target details: one is to use high-quality imaging equipment to improve the imaging resolution, or to provide image information of target details by setting multiple cameras in the scene. The disadvantage is that the cost of the video surveillance system is increased; another method is to use a video surveillance system with a PTZ camera, but at present this kind of method works through manual adjustment, and t...

Problems solved by technology

At present, there are two main methods to improve the definition of target details: one is to use high-quality imaging equipment to improve the imaging resolution, or to provide image information of target details by setting multiple cameras in the scene. The disadvantage is that the cost of the video surveillance system is increased; another method is to use a video surveillance system with a PTZ camera, but at present this kind of method works through manual adjustment, and the disadvantage is that it cannot achieve intelligence. The efficiency of detail image acquisition is relatively low

[0003] Therefore, it is necessary to solve the contradiction between the scope of video surveillance in the existing surveillance system and the collection of specific target details, and provide a video surveillance system that can effectively solve the contradiction between the two without increasing the cost
