ABSTRACT:
A method used in broadcasts of events is disclosed for identifying the coordinates of an object in world space from a video frame, where the object is not on the geometric model of the environment. Once the world coordinates of the object are identified, a graphic may be added to a video replay showing the object. The method may also be expanded in a further embodiment to identify a trajectory of an object over time moving through world space from video images of the start and end of the trajectory, where the object is not on the geometric model of the environment. Once the trajectory of the object in world space is identified, a graphic may be added to a video replay showing the trajectory.
