Detailed Description

reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

before explaining the technical scheme of the present application, a conventional pan/tilt control method and the problems thereof will be explained in detail.

in a conventional pan/tilt/zoom control method, the control panel is usually implemented by a control panel in a background monitoring device (generally, a computer), the control panel is a computer software program, the computer is used as a carrier and is connected with the pan/tilt/zoom through a data line, the control panel includes a direction button for controlling a direction, and a user can click a corresponding button in the control panel through a mouse to control the direction of the pan/tilt/zoom. However, since the control panel is usually disposed on one side of the video image area, when the control panel is used for control, the user's line of sight needs to be continuously switched between the control panel and the video image, and thus the operation process is not smooth enough. In addition, the direction keys of the control panel only comprise four keys of up-down, left-right and so only one stepping motor can be controlled to operate each time, namely, the cradle head can only be controlled to rotate towards one direction of up-down, left-right at the same time, but the cradle head cannot be controlled to rotate towards directions such as up-left, down-left and the like, and at the moment, a user needs to operate for many times, so that the operation is not convenient enough. In order to solve the above problem, an embodiment of the present application first provides a method for controlling a pan/tilt head, where the method is implemented by a user operating a mouse.
