Abstract

In this study, a real time image integrating system which can reconstruct two images from a surface camera and an under water camera into one new image was developed to support Korea artistic swimming team. The developed system consists of four USB cameras (two USB 2.0 and two USB 3.0) sealed in water proof case and one note book computer, and a LabVIEW based real time image merging program was developed. During field test, problem in cooperative motion of acrobatic formation was found, and it was proved that correction of motion to improve skill of the player could be possible in real time with aid of the developed system. After the filed test, the developed system has been being used to support Korea artistic swimming team.

본 연구에서는 국가대표 아티스틱 스위밍팀 선수들의 연기 및 동작 촬영 지원을 위해서, 수상 및 수중 카메라에서 생성된 영상을 실시간으로 하나의 통합 영상으로 재구성하는 아티스틱 스위밍 수상 수중 영상 통합 시스템을 개발하였다. 개발된 시스템은 방수 처리가 된 4대의 USB 카메라(USB 2.0 카메라 2대, USB 3.0 카메라 2대) 와 1대의 노트북 컴퓨터를 이용하여 구현 되었으며, 수집된 영상의 처리를 위해서 LabVIEW 기반의 영상 합체 프로그램을 개발하였다. 구현된 장비를 이용하여 아티스틱 스위밍의 아크로바틱 동작을 관찰한 결과 협동 동작에서 발생하는 문제점 관찰 및 원인 파악이 가능하였으며, 현장에서 효과적인 동작 지도가 가능함을 확인 할 수 있었다. 개발된 장비는 현장 실험을 통한 성능 검증 후, 국가대표 아티스틱 선수들의 경기력 향상 지원에 활용되고 있다.
