Abstract: The flying kick in Nanquan was taken for example. According to 2003 Wushu competition rules, a threedimensional coordinate system was built, and the deduction rules of flying kick error action were given a formal description. Then the error function was established. Finally, the pointdeduction model for flying kick error action recognition was established and illustrated to help electronic referees to identify the quality of the action and to facilitate the competition score (group A) referees’ decision making.
