Illegal dumping in the river is grasped by the river patrol once or twice a week, and the minimum size is about 30 cm. Since it is difficult to grasp illegally dumped wastes in low waterways that are difficult to see from embankments, it is necessary to comprehensively grasp illegally dumped wastes in the entire river area including low waterways. Compared to satellite and aerial photographs, UAV photographs are considered to be more suitable for river patrol because they are easier to take and have higher resolution. However, it takes time and effort to visually interpret illegally dumped waste from UAV photographs. Therefore, in this study, in order to realize a comprehensive grasp of the entire river area, we confirmed the feasibility and effectiveness of work efficiency improvement of the illegal dumping grasping method that combines UAV photography and AI. As a result, we were able to grasp the comprehensive distribution of illegal dumping in the entire river area from the UAV photograph, and it was confirmed that the automatic detection by AI shortened the work time to detect illegal dumping.
