Detection of rust and exposed steel bars of concrete surface of quaywalls and breakwaters by object detection, YOLO

Abstract

In order to improve the efficiency of infrastructure maintenance and management for port managers, the author has been developing a system for port and harbor facilities using AI. The system targets automatically detection of facility changes of state such as cracks, difference in levels, rust, exposed steel bars. This paper describes the AI-based detection of rust and exposed steel bars in the system. Comparing the past study, I succeeded improvement of detection of rust, but detection accuracies were not sufficient. Further improvement is needed.
