Non-blind spot novel video monitoring system

Abstract

The invention provides a blind spot free novel video monitoring, watching system. The system comprises cameras, a telecom network, and a monitoring computer. At least one of the cameras has an overall monitoring fisheyes lens with a view field range 270 degrees to 320 degrees and at least one regular zooming monitoring lens for the suspicious part detailed observation respective composes a main camera and a assistant camera with the CCD. At the same time, with the reduction of the cameras, the monitored image quantity is reduced synchronously, which decreases the working quantity of the monitoring stuffs; and under the situation of needing video, the system can save the memory hard disk space for the image documents, thereby the system increases the information of the recorded information and prolongs the recording time under the premise of the same memory distribution.

Description

technical field [0001] The patent of the present invention relates to a new type of video surveillance and monitoring system based on a fisheye lens with a field of view above 270°. Compared with the existing system, it can minimize the number of surveillance cameras, maximize the surveillance area and airspace range, and be used in conventional and special environments such as the detection and surveillance of tunnels or pipeline inner arms; it can also be used for security and military surveillance of the entire airspace ; It can also be used to assist driving in narrow waterways or road surfaces. Background technique [0002] The traditional monitoring technology in the security field has been quite mature after decades of development. Its working principle is to use a camera (composed of a lens and a CCD) to take pictures of the monitoring area and transmit them to various monitors through wired and wireless transmission. Supplemented by various image processing and man...

Problems solved by technology

[0003] However, in traditional monitoring systems, conventional lenses with a field of view of tens of degrees are generally used, and the monitoring range of a single lens is greatly limited. The number of lenses and the increase of the pan-tilt scanning device make the system larger and the circuit more complicated, which wastes resources and increases the workload of the monitoring personnel. Moreover, the scanning action of the pan-tilt itself has a certain frequency, and at a certain period of time segments still have blind spots, reducing monitoring efficiency
