摘要
以拓扑关系为依据,研究了一种新的栅格转矢量的方法——结点搜索法,与传统方法相比,不仅转换速度快,不需要预处理,而且在转换过程中即自动形成拓扑关系,因而具有简便、快速、高效的特点。试验取得了令人满意的效果,不失为一种优良的转换方法。
Based on the topological theory, this paper studied a new approach named'Node Searching' for transferring raster to vector. The main advantages of the new approach were: (1) high efficiency and high speed;(2) capable of building topological structure of vector data automatically during converting; (3) unnecessary to process raster data before converting; (4) not very sensitive to the number of raster image's column and rows. It was proved to be a good approach in experiments.
