| Abstract(in English) | In baseball games, foul balls sometimes fly into the spectators seats. Some person can be seriously wounded for those balls. This research aims at developing a system which computes the orbit of a foul ball on real time using a camera, predictes of the spot where foul balls fall and informs spectators about danger. Detection of balls consists of following three steps: At first each frame is processed using smothing filter for noise reduction. Next, temporal Laplacian are made from series of those filterd images. Finally, whether a part of a ball or not is judged for each pixels by translation the resultant images into polar coordinates. The pitching motion is also considered. |
