2D 카메라 기반 배드민턴 단식선수 이동거리 산출 기법 구현

초록

This study id intended to develop a technique of calculating a badminton singles player’s moving distance by utilizing perspective grid based on 2D camera. In this study, data were collected by using the perspective grid of Adove Illustrator CC and Dartfish Team Pro 5.5 ver., Sports video analysis S/W, with regard to the recorded video through 2D camera in order to calculated the player’s moving distance indoors where it was difficult to utilize GPS. It was possible to calculate the players’ moving distance with a formular entered in advance, using functions such as IF, ABS, and SQRT, on entering the collectedd ata in Excel 2013. It was possible to extract the player’s actual moving distance per stroke by substituting the coordinates of starting point(x1, y1), and end point(x2, y2) into the Pythagorean theorem. The results of exatrcted data showed that total moving distance per game was 2097.236m. In the future, it is thought that thee vlel can be raised up to where real-time dat a can be collected or feedback is possible by using halftime through continuous studies.
