Abstract:

In recent years,the use of remote sensing images for ship detection and surveillance and technological development has received considerable attentions in the field of ocean remote sensing.This issue has been one of the most important marine applications of remote sensing data.When the ocean remote sensing imagery is used for ship wake detection,one can discover and extract ship target information quickly and effectively.The main work of the article is to estimate ship target speed and heading by using the ship wake characteristics in the remote sensing ocean images.We use gray accumulation method and Radon transform method separately to extract wake length,and with the feature of wake length we can estimate ship speed and heading.Finally,the experimental results and error analysis are accomplished and the influencing factors in the process of ship wake detection are described simply.The experimental results verify the validation of the proposed method.
