Camera locating method and locating device of video monitoring system

Abstract

The invention provides a camera positioning method and a device thereof in a video monitoring system, wherein the method comprises the following steps: setting a target positioning interface containing a plurality of sub positioning areas, wherein each sub positioning area being corresponding to the attitude parameters of a subregion to be monitored in a region to be monitored; obtaining the attitude parameters of the corresponding subregion to be monitored when selecting a sub positioning area in the targeting positioning interface, and carrying out positioning of the camera by using the attitude parameters. According to the target positioning method and device provided by the invention, monitoring personnel can identify and select a sub positioning area visually in the target positioning interface through images and characters. A target positioning unit can obtain the attitude parameters of a corresponding target according to the selected sub positioning area, convert the target attitude parameters into corresponding action parameters of a cradle head and transmit the action parameters to the cradle head, and carry out accurate one-time positioning of the camera.

Description

technical field [0001] The invention relates to a camera positioning method and a positioning device of a video monitoring system. Background technique [0002] As a combination of traditional video technology and modern communication technology, video surveillance has attracted more and more attention at home and abroad, and has been widely used in finance, public security, transportation and other fields. The earliest video surveillance system is a fully analog video surveillance system, also known as CCTV surveillance system. The image information is transmitted from the monitoring camera to the monitor in the form of analog data through the video cable. Generally, the transmission distance cannot be too far. It is mainly used for monitoring in a small area. The monitoring image can only be viewed in the control center. With the development of digital technology, digital video surveillance systems began to appear in the mid-1990s, replacing the original analog video equi...

Problems solved by technology

This operation method is the same as the above operation method, and it is difficult to take into account the sensitivity and accuracy of the operation. If the step size is large, the camera may not be positioned accurately. Usually, it is necessary to set the fine-tuning button for further adjustment, which is troublesome to operate.

[0008] No matter which of the above-mentioned operating devices or operating methods is used, there will inevitably be a certain delay between the operation command issued by the operator and the execution of the operation command by the pan / tilt motor. There is a certain delay, so from the control point of view, it is difficult to achieve a quick one-step camera
