Zanin Multidisciplinaria (Ciencias Naturales y Exactas) road seeds road objects road extraction digital photogrammetry ABSTRACTThis article presents an automatic methodology for extraction of road seeds from high-resolution aerial images.The method is based on a set of four road objects and another set of connection rules among road objects. Eachroad object is a local representation of an approximately straight road fragment and its construction is basedon a combination of polygons describing all relevant image edges, according to some rules embodying roadknowledge. Each one of the road seeds is composed by a sequence of connected road objects, in which eachsequence of this type can be geometrically structured as a chain of contiguous quadrilaterals. Experimentscarried out with high-resolution aerial images showed that the proposed methodology is very promising inextracting road seeds. This article presents the fundamentals of the method and the experimental results, aswell. 2005 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32777311 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.3 Vol.77 |
