Summary:The invention provides a rapid segmentation method for a remote sensing image port water surface target. The rapid segmentation method relates to the field of remote sensing image processing, and solves the problem that the requirement of real-time performance cannot be satisfied due to high computation complexity, poor robustness of the existing image preprocessing method. The rapid segmentation method comprises the steps of: preprocessing an image; performing binarization processing on the original image to realize sea-land segmentation; extracting angular points of the image after binarization processing, and acquiring an image after sea-land segmentation; performing connected domain processing on the image after sea-land segmentation, acquiring a total number of connected domains, calculating the circumference of the connected domains, and determining the connected domains with a total number of connected domain pixel points greater than a connected domain circumference threshold value to be a land portio
