    摘要: 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.

    摘要: A system is disclosed that can be used to enhance a video of an event. Sensors are used at the event to acquire information. For example, the system can include pan, tilt and zoom sensors to acquire camera view information. This information can be added to the video signal from a camera (e.g. in the vertical blanking interval) or otherwise transmitted to a central studio. At the studio, the sensor information is used to enhance the video for broadcast. Example enhancements include drawing lines or other shapes in the video, adding advertisements to the video or adding other graphics to the video.

    摘要: A system determines 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 system includes determining the height that a basketball player jumped and adding a graphic to a television broadcast that displays the determined height. The system includes two or more cameras 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 determined the vertical position.

    摘要: A telestrator system is disclosed that allows a broadcaster to annotate video during or after an event. For example, while televising a sporting event, an announcer (or other user) can use the present invention to draw over the video of the event to highlight one or more actions, features, etc. In one embodiment, when the announcer draws over the video, it appears that the announcer is drawing on the field or location of the event. Such an appearance can be performed by mapping the pixels location from the user's drawing to three dimensional locations at the event. Other embodiments include drawing on the video without obscuring persons and/or other specified objects, and/or smoothing the drawings in real time.
