Measurements of the Thickness and Area of Thick Oil Slicks Using Ultrasonic and Image Processing Methods

The in situ measurement of thick oil slick thickness (>0.5 mm) and area real time order to estimate the volume an spill is very important for determining response strategy evaluating disposal efficiency. In this article, a method proposed assess slicks by simultaneously measuring using ultrasonic inspection image processing methods, respectively. A remotely operated vehicle (ROV), integrating two immersion transducers, was implemented as platform receive reflections from slick. determined multiplying speed sound traveling within slick, which calculated cross-correlation method. Images were captured optical camera airborne drone. conducting on images algorithms. Multiple measurements performed verify laboratory experiments. results show that thickness, can be accurately measured with could potentially used applicable tool during response.
