Abstract

A system is disclosed that can determine the vertical position of an object and report that vertical position in a format suitable for use on a television broadcast, a radio broadcast, the Internet or another medium. One example of a suitable use for the present invention includes determining the height (62) that a basketball player jumped and adding a graphic (74) to a television broadcast that displays the determined height. The system includes two or more cameras (20, 22, 24, 26) that capture a video image of the object being measured. The object's position in the video images is determined and is used to find the three-dimensional location of the object. The three-dimensional location includes a height coordinate. In some cases, the height coordinate is the desired vertical position. In other cases, the height or size of the object may be subtracted from the height coordinate to determine the vertical position.
