Abstract

A control system of a PTZ (Pan Tilt Zoom) photographic device is applied to a handheld device which is connected with the PTZ photographic device through a network. When a user selects to access the PTZ photographic device, the control system transmits an initialized signal to the PTZ photographic device to enable a lens of the PTZ photographic device to be adjusted to the initial position and receives and displays obtained initial images in a monitoring area through photographing of the PTZ photographic device. The control system converts tilt information of the handheld device to rotating information of the lens according to preset relevance and sends the rotating information to the PTZ photographic device so as to control the lens to rotate correspondingly and receives obtained current images in the monitoring area through re-photographing after rotation of the lens. When the user performs zoom adjustment on the current images displayed on a display screen, the control system converts an adjustment ratio of the current images to an adjustment ratio of a focus length of the lens according to the preset relevance and sends the adjustment ratio of the focus length of the lens to the PTZ photographic device so as to adjust the focus length of the lens. The invention further provides a control method of the PTZ photographic device.

Description

technical field [0001] The invention relates to a remote control system and method, in particular to a system and method for remotely controlling a PTZ camera device. Background technique [0002] Panning, tilting, zooming (pan, tilt, zoom, PTZ) camera devices are generally controlled by the monitoring personnel through the controller of the monitoring center to control the panning, tilting, and zooming operations of the lens. If the monitoring personnel leave the monitoring center, they cannot know the real-time images of the monitoring area taken by the PTZ camera device in time, nor can they control the movement of the lens in time. Contents of the invention [0003] In view of the above, it is necessary to provide a PTZ camera control system and method, which can allow users to automatically control the rotation and zooming operations of the PTZ camera lens through a handheld device. [0004] A PTZ camera control system is applied to a hand-held device, and the hand-h...
