Firstly,the Delaunay triangle nets of scattering soungdings are built and the topologic relation of points,edges and triangles are saved.Secondly,the average distance of close points is used as limited distance for the borderline of soundings.Finally,the results of topologic relation and the limited distance are applied for extracting the soundings'borderline.By the experiment,the method is provided with the characteristics of simple structure,convenient operating,low-occupied memory and high efficiency,which turns the borderline's quickly extracting from scattering soundings into reality.
