This paper presents a sensor system for detecting defects in ship hull surfaces. The sensor was developed to enable a robotic system to perform grit blasting operations on ship hulls. To achieve this. the proposed sensor system captures images with the help of a camera and processes them in real time using a new defect detection method based on thresholding techniques. https://www.spidertattooz.com/Orly-Nail-Lacquer-For-The-First-Time-20931-p28703/
