1. A ball tracking system comprising:

  • a display;

    a sensor positioned to detect a plurality of observed ball flight paths, each in the plurality originating from a different ball strike at a different location; and

    wherein the sensor is correlated to three-dimensional space;

    a launch monitor positioned to detect one of the ball strikes and to measure the launch parameters of that ball strike;

    a processor connected to the display, sensor and launch monitor, wherein the processor is adapted to perform the following steps;

    a. receive the launch parameters from the launch monitor;

    b. calculate a predicted ball flight path based on the launch parameters;

    c. receive image data from the sensor;

    d. from the image data, identify an observed ball flight path and a landing event for each of the plurality of observed ball flights paths, further comprising the steps of;

    (1) capturing image frames;

    (2) performing ball detection within the image frames;

    (3) grouping detected balls based on spatial position and time that is characteristic of a ball in motion to form a bail trajectory; and

    (4) performing landing event identification based on a discontinuity in the ball trajectory in successive image frames;

    e. determine a landing location for each identified landing event;

    f. based on the predicted ball flight path determine a matching distance for each of the plurality of landing locations; and

    g. select the matching distance that is closest to the predicted ball flight path.
