[Abstract]:Ship target detection based on optical remote sensing image is an important research direction in the field of ocean target detection, especially at the present stage when the maritime security situation is becoming more and more complicated. Ship target detection based on space-borne optical remote sensing images has become the research focus of scholars and experts from all over the world. It has important research significance and broad application prospect in waterway traffic management, sea area monitoring and other fields. In this paper, aiming at the problems of fast detection of ship target and accurate estimation of ship velocity in visible light remote sensing image, the common algorithms of target detection and ship velocity estimation are introduced, and the principle frame of ship target detection and ship speed detection is established. Then, a ship target detection algorithm based on visible light remote sensing image is proposed, which takes noise image, uneven illumination image and cloud and fog interference image as the research object, combined with the sea and land complex background image and the imaging characteristics of ship target. Using image preprocessing, image processing and anti-cloud interference algorithms, the ship target detection under the complex background of sea and land is realized quickly and accurately. Finally, according to the characteristics of moving ship wake imaging in different resolution remote sensing image, The physical relationship between ship wake parameters and ship velocity is studied, and two methods for ship velocity estimation at different resolution are proposed.
