영상분석을 통한 테니스 엘리트 선수들의 움직임 분석 = Analysis of Movement for Elite Tennis Players through Image Analysis

다국어 초록 (Multilingual Abstract)

This paper has been investigated to present a plan that leads favorable games through analysis of major causes of scores in elite men`s singles tennis. It has inspected the image analysis in 3 dimensions of every single set in High school level of men`s singles tennis. By analyzing move distributions that affect the final consequences, it has found an approach of leading the games. There are the consequences due to variables of move from the image such that were filmed on a whole part of the court. the 3 dimensional coordinates of tennis balls and players were found through DLT techniques and the S/W analysis. First, as a result of investigating the actual match time, the time taken was 29 minutes 28 seconds and the real game time took 364.18 seconds approximately 6 minutes 7 seconds. Moreover, it wasted about 4 times more outside of the games than real match time, 22 minutes 58 seconds. Second, it has realized that the total distance of the players moved was not influenced to the consequence of the match, however, it can be seen that taking possessions of the net to lead the favorable game due to the distance of movement forward and backward and also the distance between ball and net affect the final results. Third, the average speed of movement were estimated in absolute distance is 132.36cm/s for winner and 87.67cm/s for loser. The winner had 44.69cm/s faster. Fourth, the movement distributions of the court were targeted the backhand of the opposite player and its range of the loser was largely distributed. As summary of this study, the winner has greater numbers of balls near the net relatively compared to the loser. Therefore it is important to take the net to get the upper hand of the tennis match.
