<p>A method for calibrating a PTZ (pan, tilt, and zoom) camera using a fixed camera, the method comprising: adjusting a pan and tilt of the PTZ camera such that a field of view of the PTZ camera overlaps a field of view of a fixed camera; receiving, by a computing system, a first set of coordinates associated with a first location in the field of view of the fixed camera; receiving, by the computing system, a second set of coordinates associated with the first location in the field of view of the PTZ camera; and calculating, by the computing system, a set of transform parameters, using the first set of coordinates associated with the first location in the field of view of the fixed camera and the second set of coordinates associated with the first location in the field of view of the PTZ camera. 110 120, 130 140, Fixed Position Fixed Position Camera Camera PTZ Camera Slave Camera Digital Signal Processor Video Compressor Router Host Computer System Metadata Server Video Server User Terminal</p> |
