AI Technical Summary
Under conditions of drastic tidal changes, existing technologies struggle to maintain the continuity of marine oil spill boundaries in nearshore environments, and oil film boundary features are prone to drift.
By acquiring remote sensing images and tidal observation data of the target sea area, a tidal mapping field is generated. The initial features of the oil film are spatially regularized using a dynamic regularization algorithm to generate an aligned feature set. Based on the corrected mapping field, elastic correction is performed to construct an oil film diffusion topology map. Structural reasoning is performed based on the node relationships in the topology map to determine the oil film diffusion boundary.
Under conditions of drastic tidal changes and synchronous changes in the shallow water background, it is essential to maintain the continuity and accuracy of the oil slick area boundary to achieve rapid decision-making and emergency response for the oil spill area boundary.
