Abstract

Video monitoring techniques and their applications to beaches were reviewed. The recent development of video hardware and image process made it possible to measure shoreline changes, sandbar morphology, wave runup, swash motion, and so on using video camaras. Especially, quantitative information from the video image can be obtained by digitization of image, rectification procedure, and image process. Using video monitoring techniques, measurements can be made at much lower cost and for long periods of time compared to the traditional measurement techniques, although these techniques are of lower accuracy and provide only indirect information on the land and water surface.

비디오_모니터링 기술 및 이의 해안에서의 적용에 대하여 검토하였다. 최근에 비디오 하드웨어 및 영상처리 기술의 발달로 인하여 비디오카메라를 이용한 해안선 변화, 연안 사주의 형태, 파의 쳐올림 및 스워쉬(swash)운동 등에 대한 관측이 가능해졌다 특히 영상의 디지털화(digitization),좌표수정(rectification)및 영상 처리과정을 통하여 비디오 영상으로부터 정량적인 정보를 얻을 수 있게 되었다. 비디오 모니터링 기술은, 비록 정밀도가 낮고 육지 및 해수 표면에 대한 정보만을 간접적으로 제공하지만, 기존의 관측 기술에 비해 훨씬 적은 비용으로 장기간의 관측을 가능하게 해 준다.
