Voronoi Centerline-Based Seamline Network Generation Method

Seamline network generation is a crucial step in mosaicking multiple orthoimages. It determines the topological and mosaic contribution area for each orthoimage. Previous methods, such as Voronoi-based AVOD (area Voronoi)-based, may generate holes low-overlap irregular orthoimage cases. This paper proposes Voronoi centerline-based seamline method to address this problem. The first detect edge vector of valid region; second construct triangle using points extract centerline network; third segment by generated centerlines image effective polygon (EMP). final segmented EMP region. All EMPs are interconnected form network. main proposed that it solves when processing with low overlap, limitation AVOD-based shape requirement, which can complete any overlap Five sets experiments were conducted, results show surpasses well-known state-of-the-art commercial software terms adaptability effectiveness.
