Abstract

A video monitoring system comprises fisheye shooting tube, mode control module, network interface, storage module, control module, calibration module and realization module. It is featured as obtaining fisheye image by wide-angle shooting tube then sending it to network interface after it is processed by mode control module, sending processed fisheye image to control module by network interface for storing said image in control module, utilizing calibration module to calibrate processed fisheye image to be planar image being displayed by display module.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a scheme for capturing and transmitting video data in the process of video monitoring. technical background [0002] With the improvement of people's living standards and the development of science and technology, security monitoring systems are being used more and more. For example, for the safety of companies, institutions, families and other places that need to be monitored, it is necessary to install safety monitoring systems in these places. In order to effectively monitor the security of the monitoring area, it is often necessary to install multiple cameras to monitor their respective areas, so as to achieve the effect of overall monitoring. However, numerous cameras not only increase the production cost of the monitoring system, but also increase the difficulty of system maintenance. [0003] With the development of lens and sensor technology, wide-angle cameras with larg...
