배드민턴 선수의 타구 예측능력 측정을 위한 다채널 영상 음향 통합 시스템 개발

Abstract

In field of motion analysis or related researches, video recording device is commonly used as a measurement system. Because the video recording device can gather more information than other measurement systems, and operation/construction of it is simple and cheap. However the video recording system has many merits for the researches, modification of the video recording system is always needed. It is due to that the general video recording devices do not satisfy requirements of various researches. Therefore, it is important that proper modification or reconstruction of the general video recording devices to adapt purpose of the researches. In this paper, a special system is developed to apply a research that analyzes motion and eye movement of badminton players. The developed system consists of a multi channel image process board, a personal computer and a sound-electric conversion circuit. It can merge four video images into one video image synchronously, and record the merged video image on a hard disc drive(HDD) of the computer in real time. Moreover, the sound-electric conversion circuit can light LED on the merged image frame to mark a reference point when smash of shuttlecock arises. Because the developed system is designed with commercial off the shelf(COTS) devices, developing time and cost can be minimized.
