The cinematographic image taken by the video camera during the game was reflected on the screen of notebook computer. After digitizing the middle point of player's feet, the position of serve receiving formation and the location passed actually were calculated by Two-dimensional Direct Linear Transformation Method. The performance of serve reception was evaluated into three grades, where a pass that can be set into combination play was +1, a pass that can be set to either end spiker was 0, an ace or pass that can't play attacking was -1. The analyzed data was expressed graphically on the screen so that the coach could supplement important strategy in brief time-out period. The scouting program has been tested and validated as video tape recorded the match was played back.
