Video monitoring device and tracking and recording method based on linkage camera

Abstract

The invention relates to a video monitoring device and a tracking and recording method based on a linkage camera. The monitoring device comprises a linkage camera device and a computer, wherein the linkage camera comprises a first camera arranged on a first movement control platform and a second camera arranged on a second movement control platform, and the second movement control platform is fixedly connected with the first camera to follow the first camera to synchronously move; and the computer is connected with the two cameras through a data communication interface and the two movement control platforms, controls the first camera to track and position a target entering a monitored area, controls the second camera to align the target and to capture the close-up details of the tracked target, and achieves video monitoring and intelligent recording of the target. The device not only can track and record a movement process of the target in the monitored area and the close-up details of the target, but also can normally work on a mobile carrier, track and record the target which enters the monitored area and keeps stationary for a long time, save memory space and reduce hardware cost.

Description

Technical field [0001] The invention belongs to the field of video monitoring, in particular to a dual-camera follow-up video monitoring device and a tracking recording method thereof. Background technique [0002] With the rapid development of electronic information technology, people's requirements for security products are getting higher and higher. Security products based on video surveillance have been widely used. For example, banks, customs, stations and high-end office buildings have installed video surveillance devices. , The security capabilities of these places have been improved. Existing video surveillance devices generally suffer from poor video quality, inability to zoom in on the tracking target and capture close-up details, resulting in the inability to identify the target in the recorded video image and the inability to conduct effective judicial forensics and identification. In order to overcome this problem, the Chinese invention patent application with the ap...

AI Technical Summary

Problems solved by technology

Existing video surveillance devices generally have poor video quality, cannot zoom in on the tracking target and capture close-up details, resulting in the inability to identify the target in the recorded video image, and cannot carry out effective judicial evidence collection and identification.

In order to overcome this problem, the Chinese invention patent application with the application number 200710012370.7 titled "Intelligent Target Detail Capture Device and Method in Video Surveillance System" introduced a video surveillance device, although high-quality video recording and The capture of close-up details of the tracking target, but this device has the following problems: ① the designed device is installed on a mobile carrier or platform, and its function will basically fail; Complicated and costly; ③It can only capture close-up details and does not have the function of intelligent analysis; ④The video recording method adopted is very blind, recording a large amount of meaningless video data, resulting in varying degrees of Waste of hardware storage space

Moreover, the existing target tracking method uses the motion detection method to only capture the moving target. When the moving target is still in the scene for a long time, the target will be misjudged as the background area, resulting in the inability to accurately track the target.

These problems have seriously affected the actual promotion and application effect of the existing video surveillance system
