Abstract:
Embodiments of the present application provide an automatic focusing method and a PTZ camera. The method is applicable to the PTZ camera and comprises: calculating a current target object distance from a lens of the PTZ camera to a monitored target monitoring plane based on a pre-established spatial object distance parameter; wherein, the spatial object distance parameter contains a spatial plane equation of a reference monitoring plane; the reference monitoring plane is an equivalent plane of the target monitoring plane; searching in a preset relation table based on the current target object distance, a current magnification of the PTZ camera, determining a position information corresponding to a focus motor of the PTZ camera, the preset relation table including the relationship of the object distance, the magnification and the position information of the focus motor, and driving the focus motor to a position corresponding to the determined position information. Embodiments of the present application are applied to realize fast automatic focusing of the PTZ camera.

Claim (Index 10):
The PTZ camera of  claim 9 , wherein the second determining sub-module comprises:\n a first obtaining unit, configured for obtaining a distance from any target point in a spatial rectangular coordinate system to the lens of the PTZ camera, wherein an origin of the spatial rectangular coordinate system is an intersection of rotation axes of the PTZ camera; the rotation axes of the PTZ camera comprise a rotation axis about which the PTZ camera rotates in a horizontal direction and a rotation axis about which the PTZ camera rotates in a vertical direction; a second obtaining unit, configured for obtaining a position information of the lens of the PTZ camera in the spatial rectangular coordinate system; a calculating unit, configured for calculating the spatial coordinates of any target point based on the distance and the position information of the lens of the PTZ camera in the spatial rectangular coordinate system.
