| Abstract(in English) | In order to analyze teamworks of team sports, it is necessary to extract players' positions and their movements out of video data, but we have to do almost all the work manually in the present technology. To cut down this burden, we study an interactive system. There are three major problems, which are the extraction of players' coordinates in the image plane, the conversion of them to the positions in the real field, and the identification of the same player in different frames. In order to solve these problems, we respectively applied simple image processing techniques, the projective transformation and a minimum-cost transportation algorithm. |
