ABSTRACT
In this paper, the authors propose the system for autonomous breakwater inspection. The system is composed of two parts; mission planning and data analysis pipeline. Mission planning is for setting flight configurations such as height, velocity, and path. The data analysis pipeline detects changes in breakwater using point cloud. This paper mainly discusses the data analysis pipeline and the results of its evaluation with simulation and field tests. The authors tested the system performance in simulation and field experiments. The results of the evaluation in simulation show that the system can detect changes such as the addition of objects, and removal, and movement of breakwaters. The authors also compared the result of the simulation and field test to check if the system works well under the actual situation. The results of field tests show the system has enough resolution to detect the addition, removal, and movement of a breakwater in the real environment.
