Abstract

The invention discloses a method and system for detecting and repairing sun glint in UAV optical RGB ocean image, introduces a sun glint attention module, and constructs a semantic segmentation network model based on attention mechanism. The sun glint region is segmtioned by semantic segmentation network model based on attention mechanism, and the optical flow field of high-resolution UAV optical RGB ocean image is extracted by RAFT optical flow estimation network. sun glint region and optical flow field are used for optical flow propagation to repair the sun glint in UAV optical RGB ocean images and restore the real benthic image features.
