ABSTRACT

Recently, problems have arisen in small and medium-sized reservoirs used for agriculture, such as cave-in incidents during local heavy rainfalls, owing to its deterioration and safety degradation. In this study, we acquired stereo images using stereo closed-circuit television (CCTV) and developed an automatic system that can measure water level changes in order to efficiently manage small and medium-sized reservoirs that are vulnerable to disasters. The system was developed using the unified modeling language (UML) and implemented by testing the CCTV. Epipolar geometry was utilized after reading the key points and conjugate points of the acquired images. The water level changes were then analyzed by producing a disparity map through the image matching using a normalized cross-correlation algorithm. The stereo CCTV-based automatic water level measurement system developed in this study exhibited a high accuracy compared to the conventional system.
