Virtual strike zone

A method of providing strike zone information, comprising the steps of:

• determining one or more locations of a ball;
• and
• indicating whether said ball intersects a strike zone;
• wherein said step of determining includes the steps of:
• receiving a set of video images that depict said ball, said video images include multiple data,
• identifying which data of said multiple data corresponds to said ball using a series of filters, each filter potentially removes data from consideration as a candidate for said ball, and
• using said data that to corresponds to said ball to automatically determine said one or more locations.

A method of providing strike zone information, comprising the steps of:

• determining a location of a strike zone for a first batter by receiving an indication of one or more positions on said first batter in an image of said first batter and using said indicated positions to automatically calculate height of said strike zone;
• determining a first position in a video, said first position corresponding to said location of said strike zone;
• and
• adding an image for said strike zone to said video at said first position.

An apparatus for providing strike zone information, comprising:

• a set of image sensors arranged to sense data about a ball and a strike zone;
• and
• a first set of one or more processors in communication with said image sensors, said first set of one or more processors use data from said sensors to determine one or more locations of said ball and determine a location of said strike zone;
• a second processor in communication with said first set of one or more processors, said second processor receives an indication of a first camera of a set of cameras, accesses transformation data specific to said first camera from sets of transformation data specific to each of said cameras and transforms said one or more locations of said ball and said location of said strike zone, to two dimensional positions in a video from said first camera;
• a third processor in communication with said second processor, said third processor prepares an image of said strike zone and an image of said ball;
• and
• a video modification unit in communication with said third processor and able to receive video from said cameras, said video modification unit receives said image of said strike zone and said image of said ball, said video modification unit adds said image of said strike zone and said image of said ball to said video from said first camera.
