Abstract

In this study, the following analyses were conducted to determine the potential applications of CCTV for multifunctional use in agricultural water resource management. First, an investigation of changes in agricultural water use revealed that agricultural water use has increased due to consecutive droughts in recent years. Accordingly, a monitoring system for agricultural river water use was proposed as an appropriate utilization measure. Second, the introduction of a video-based flow velocity measurement technique was suggested as a simple method for measuring the amount of water flowing through irrigation channels. Since 6,021 CCTV cameras currently in operation are IP cameras, it was confirmed that there is a high potential for multifunctional utilization through video-based flow velocity measurement. Additionally, considering the characteristics of irrigation channels, which generally have a relatively stable flow, achieving a certain level of accuracy is more critical than high precision. Therefore, the LSPIV (Large-Scale Particle Image Velocimetry) method was deemed to be more efficient in terms of maintenance and management compared to conventional direct measurement methods. Based on the existing system, this study proposes a method in which videos captured in the field are transmitted to a central platform, where they are analyzed to estimate water level, flow velocity, and discharge. These results can then be accessed by regional offices. Moving forward, the development and pilot operation of a related platform are necessary to expand the CCTV-based agricultural water resource survey system.

이 연구에서는 농업용 수자원 관리에서 CCTV의 다목적 활용 가능 분야를 결정하기 위해 다음과 같은 분석을 수행하였다. 첫째, 농업용수 사용량 변화를 조사한 결과, 최근 연이은 가뭄으로 인해 농업용 하천수 사용이 증가하고 있음을 확인하였다. 이에 따라 농업용 하천수 사용량 모니터링 체계가 적절한 활용 방안임을 제안하였다. 둘째, 간단한 방법으로 용수로에 흐르는 수량을 측정할 수 있는 영상 유속 측정 기법의 도입을 제안하였다. 현재 운영 중인 6,021개소의 CCTV가 IP 카메라로 운용되고 있어, 영상 유속 측정을 통한 다목적 활용 가능성이 높음을 확인하였다. 또한, 비교적 안정적인 흐름을 갖는 용수로의 특성 등을 고려할 때, 정교함 보다 일정 수준의 정확도 확보가 요구되므로 영상 유속 산정 기법 중 LSPIV(Large-Scale Particle Image Velocimetry) 방법이 기존의 직접 측정 방식보다 유지 ‧ 관리 측면에서 더욱 효율적일 것으로 판단되었다. 이에 기존 방식을 바탕으로, 현장에서 촬영한 영상을 중앙으로 전송한 뒤 중앙 플랫폼에서 이를 분석하여 수위, 유속, 유량을 산정하고, 각 지사에서 조회할 수 있는 시스템을 제안하였다. 향후 관련 플랫폼의 개발 및 시범 운영을 통해 CCTV 기반 농업용 수자원 조사 체계를 확대하고자 한다.
