The invention discloses a method and system for calculating the length of a dry beach based on image processing, and the method comprises the steps: obtaining a dry beach image data set, processing a dry beach image, and obtaining a feature image and a region of interest of the feature image; performing target category judgment based on the region of interest, and outputting a processed image; and selecting a reference point in the processed image. And according to a monocular distance measurement model, converting an actual coordinate system established by a target into a pixel coordinate system, deriving a conversion formula, and substituting the conversion formula into a reference point to obtain a dry beach length measurement value. By adopting the technical scheme, the accuracy of identifying the position of the boundary of the water surface of the dry beach can be improved, the length of the dry beach is further calculated, and the measurement and calculation accuracy is improved. 本发明公开了一种基于图像处理的计算干滩长度的
