Abstract

A three-dimensional model is created to represent an environment to be captured on video. A camera is fitted with pan, tilt and/or zoom sensors. An operator selects a location in the environment. The three-dimensional model is used to determine the three-dimensional coordinates of the location selected by the operator. Information from the pan, tilt and/or zoom sensors is used to transform the three-dimensional coordinates to a two-dimensional position in the video from the camera. Using the two-dimensional position of the video, a graphic is properly added to the video such that the graphic appears to be at the selected location in the environment.
