Abstract

The invention discloses a pan / tilt / zoom (PTZ) camera control method, a device and a system thereof, which can be applied to an audio / video monitoring system comprising a server, a terminal device and the PTZ camera. The method comprises the steps of: using the terminal device to receive the control command of the PTZ camera sent by the server, wherein the control command contains the coordinate parameter of the target imaging area of the PTZ camera in the current image window; using the terminal device to confirm the rotating direction, the rotating speed, the rotating time and the zoom time of the PTZ camera according to the coordinate parameter of the target imaging area as well as the equipment parameters of the PTZ camera; and using the terminal device to control the PTZ camera to rotate according to the confirmed rotating direction, rotating speed and rotating time, and control the PTZ camera to zoom according to the zoom time. The invention can be used for improving the compatibility of the audio / video monitoring system.

Description

A kind of PTZ camera control method and its device and system technical field The invention relates to audio and video monitoring technology in the communication field, in particular to a method for controlling a pan-tilt camera and its device and system. Background technique Audio and video monitoring is the physical basis for real-time monitoring of key departments or important places in various industries. Management departments can obtain effective data, images or sound information through it, and monitor and record the process of sudden abnormal events in time. As shown in Figure 1, the audio and video monitoring system includes cameras, transmission network, terminal equipment and servers to realize the recording, storage, display and various control functions of audio and video data. Among them, the server is mainly used for the management of the audio and video monitoring system and the control of the camera; the terminal device is mainly used for encoding the vide...
