| 摘 要： | 本文在详细分析线要素的拓扑关系和弧段拓扑建立中的自动剪断线方法的基础上,引入扫视求交法,重点探讨了自动剪断线算法在线状要素合并中的应用。通过合并自相交与线状要素之间相交两步过程,引入求交前的预处理,提高了自动剪断线的效率。最后对本方法进行了简单的试验分析。

| Abstract: | This article introduces scanning junction method and discusses with emphasis the application of the broken line method automatically in the striation essential factor merge,based on describing in detail the automatically broken line method of the establish- ment of line factor's topology and arc topology.Through two steps of intersection merging automatically and line factors's mutual in- tersection,introduces pretremeat before intersection,improving the efficiency of cutting line automatically.Finally make a simple ex- periment. |
