Abstract

The present invention discloses a pan tilt and zoom lens control task operating method of terminal camera device and a device thereof, wherein the method and device are used for video monitoring system which is based on network. The pan tilt and zoom lens control task operating method comprises the following steps: singly establishing a task which is closed when a control instruction is not received for pan tilt and zoom lens control; when the control instruction is transmitted, arousing the pan tilt and zoom lens control task by the instruction task and transferring the control instruction to the pan tilt and zoom lens control task; transmitting the control instruction to a pan tilt and zoom lens controller by the pan tilt and zoom lens control task for causing the pan tilt and zoom lens controller to drive the pan tilt and zoom lens to move according to control instruction. The invention adopts a mode of singly establishing the pan tilt and zoom lens control task to cause that the pan tilt and zoom lens control task of terminal camera shooting device operates more smoothly.

Description

technical field [0001] The invention relates to a method and device for operating a pan-tilt control task of a terminal camera device, in particular, the method and device are used for a terminal camera device in a network-based video monitoring system. Background technique [0002] With the development of multimedia technology, multimedia monitoring system is more and more used in security protection, remote monitoring, distance teaching, distance conference, distance presentation, community service and other fields, and plays an important role.
