Master-slave target monitoring system and method in combination of fisheye camera and PTZ camera

Abstract

The invention discloses a master-slave target monitoring system and method in combination of a fisheye camera and a PTZ camera. The system is characterized by comprising a fisheye camera, a PTZ camera and a processing host; the fisheye camera is a master monitoring camera, the PTZ camera is a slave monitoring camera. The master monitoring camera in the invention adopts the fisheye camera to realize seamless monitoring of stand-alone hemisphere space and the moving target detection; the slave camera adopts the PTZ camera so as to realize the high resolution directional imaging to a specific target. The advantage of being large in monitoring range of the fisheye camera is sufficiently integrated, and meanwhile, the defect that the image of the fisheye camera is serious in deformation and low in resolution due to huge distortion is overcome through the directional secondary imaging of the PTZ camera, the fisheye camera and the PTZ camera are supplemented with each other so as to realize a real sense of single-system hemisphere space seamless monitoring function.

Description

technical field [0001] The invention relates to a super-large-range target monitoring system, in particular to a single-system super-wide-range seamless master-slave target intelligent monitoring system and method combined with a fisheye camera and a PTZ camera. Background technique [0002] With the continuous industrialization and rapid economic growth in modern society, people's living standards are gradually improving, and their safety awareness is becoming stronger and stronger. Therefore, more requirements are put forward for the safety of the living and working environment. In recent years, with the development of video surveillance technology, people are increasingly aware of the importance of video surveillance technology in life. The wide application of video surveillance technology in key security monitoring areas such as road traffic, banks, and residential areas has effectively deterred various potential crimes and guaranteed people's life safety. However, most...

Problems solved by technology

However, most of the existing monitoring systems are still in the stage of video storage and playback, lacking intelligent analysis functions. Seamless monitoring of key areas, but complex structure, high cost and difficult maintenance

However, the use of a simple fisheye lens with a large viewing angle can achieve 180° or more area monitoring with a single lens, but due to serious distortion, there are problems of poor stability and reliability in the later intelligent analysis and processing.
