Sea ice outer edge line extraction method and device, electronic equipment and storage medium

The invention provides a sea ice outer edge line extraction method and device, electronic equipment and a storage medium, and relates to the technical field of ocean remote sensing, and the method comprises the steps: obtaining an optical remote sensing image of a preset ocean region; performing preliminary sea ice extraction processing on the optical remote sensing image to obtain a sea ice extraction matrix (used for representing a plurality of connected regions satisfying a preset range); carrying out broken ice identification processing on the plurality of connected regions to obtain broken ice regions, and removing the broken ice regions to obtain a target matrix; converting the target matrix after the broken ice area is removed into a target image, and performing grid-to-vector processing on the target image to obtain a vector surface file; and removing a background vector surface in the vector surface file, and carrying out vector surface line conversion processing to obtain a sea ice outer edge line.
