Abstract
a new al gorithm based the delaunay trian gulated network and its improved al gorithm isproposed to implement area feature automatic skeleton line extraction.a delaunay trian gulated network al gorithm was improved to be better applied to more complex area feature of the trian gular network establishmentthe existence of a lar ge number of smaller trian gles in the facet element trian gulation boundary re gion was carried outan effective processing al gorithm was proposed to improve theskeleton extraction efficienc ytrian gle was considered the smallest unit as a node of the tree and an ef fective binar y tree structure based on trian gulation was presentedtrifurcate chain-table stora ge structure was used to make the binar y tree traversal more strai ghtforward.the experimental resultsshowed that the proposed concepts and al gorithms for main skeleton extraction to be more effective.
