Ship wake detection method based on top hat transformation and Radon transformation

The invention discloses a ship wake detection method based on top hat transformation and Radon transformation, and the method comprises the steps: obtaining an original image, processing the originalimage based on the top hat transformation, and obtaining an image with improved contrast; and performing Radon transformation on the image with the improved contrast, extracting a peak point, obtaining wake position information, and marking a wake in the image. The method provided by the invention has a contrast improvement effect on both the bright wake and the dark wake, and the dark line feature of the dark wake can be converted into the bright line feature; radon transformation is carried out on the image with the improved contrast ratio, and a peak point in a Radon transformation domain is highlighted, so that the detection performance of the ship wake is improved; the method can be applied to ship wake detection in Tiangong-2 interferometric three-dimensional imaging microwave altimeter images. 本发明公开了一种基于顶帽变
