Baseball Pitch Tracking System BeachTrack & BeachTrack Lite VolleyTrack Shuttlecock Tracking GAA- Point Detection System Tennis: Hawk-Eye Live Electronic Line Calling Cricket: Cricket Ball Tracking UltraEdge The original ball tracking system that was used in cricket was hawk-eye, which is able to trace a cricket ball's trajectory, with a claimed accuracy of 5 mm, which can be used to adjudicate LBW decisions.More recently, a rival system Virtual Eye (also called Eagle-Eye) provides a similar service. If you then put together the range of rulings for each lbw appeal, you will find that some appeals will have been ruled out by a majority - or even all - of umpires, others will have been ruled not-out by a similar majority. If we are to assess this new alternative, it has to be compared reasonably to the traditional method used by umpires. Weve discussed this earlier and Im sure most of you will be familiar with the hawk-eye in cricket. The team has tested its algorithm on a number of video sequences of various volleyball, basketball, and soccer games. Notify me of follow-up comments by email. But, its a time taking process as it considers several patches of the image. This approach is known as the sliding window approach., since we slide the window of a patch in each part of an image.
