Cruise control method for tripod head video camera

Abstract

The invention provides a cruise control method for a tripod head video camera. The method is applied to a video monitoring system which comprises the tripod head video camera, a video server and a client terminal. The method comprises the steps that (S1) a panoramic picture of a monitorable area of the tripod head video camera is displayed on the client terminal; (S2) the client terminal collects position coordinates of a tracing point on the panoramic picture and sends the position coordinates the video server every other preset time, and the video server generates control parameters by combining the position coordinates of the tracing point collected latest and sends the control parameters to the tripod head video camera; (S3) the tripod head video camera controls own rotation according to the control parameters, and the own optical axis of the tripod head video camera is made to be located on a same straight line with a ground location coordinate corresponding to the position coordinates of the tracing point collected latest. According to the cruise control method for the tripod head video camera, the rotation of the tripod head video camera can be control by moving the tracing point, a user can acquire all the information around a monitoring point conveniently through the panoramic picture, observation and judgment over an overall situation by the user are facilitated, and therefore better monitoring effects can be achieved.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to a cruise control method for a pan-tilt camera. Background technique [0002] Video surveillance is an important part of the security system. With the rapid development of computer, network communication and image processing technologies, video surveillance technology has also made great progress. At present, video surveillance technology has been widely used in various fields, especially in some fields such as public safety and emergency command. [0003] In the current video surveillance system, in order to reduce the deployment density of cameras, PTZ cameras are deployed at many monitoring points. Using the rotation and zoom functions of the PTZ camera, one PTZ camera can monitor a large area in real time. Whether the operation of the PTZ camera is fast or not has become an important indicator in the monitoring system, which affects the user's use effect to a larg...

AI Technical Summary

Problems solved by technology

[0006] The field of view is limited; the user cannot intuitively see all the areas that the PTZ camera can monitor, especially for the 360-degree rotating PTZ camera, when the user rotates the PTZ camera by moving the track point on the monitoring screen, it is difficult to rotate the PTZ camera from different angles. It is not conducive to the overall observation and judgment

[0007] The rotation of the pan/tilt is discontinuous; in the above scheme, the pan/tilt camera is turned from the static s
