    摘要： A method and system for converting privacy zone corner points in a still image to PTZ coordinates using the equations for distance along the great circles of a sphere, where the sphere is defined along the pan-tilt axes of a PTZ camera with radius equal to the focal length of the image. The method includes receiving planar coordinate data defining a plurality of privacy zone corner points, the planar coordinate data taken from a still image, converting each privacy zone corner point to corresponding spherical coordinates, converting each of the corresponding spherical coordinates to corresponding PTZ coordinates, and storing the corresponding PTZ coordinates in a storage device. The stored PTZ coordinates may then be transmitted to a computer monitor. The motor of the PTZ camera moves the camera according to the PTZ coordinates until the privacy zone corner points appear at the substantial center of the monitor screen.
