基于拓扑关系原理的栅格转换矢量方法的研究
摘要:

从与传统方法不同的角度着手,以拓扑关系为指导,研究了一种新的由栅格数据转换为矢量数据的方法。与传统转换方法相比,该方法不需对栅格数据进行预处理,它在转换过程中即形成拓扑关系,只需对图像数据逐行处理一次,故适合于大图像的处理。该方法转换效率高、速度快,并在试验中取得了很好的效果。

Study on a New Method for Transferring Grid to Vector Using the Topological Theory
Abstract:

With the different view of traditional methods, in the light of the topological theory, this paper studies a new method for converting raster data to vector data. Compared with traditional methods, the new method does not need to pro process the raster image, created topological structure of vector data during the conversion. This method processed raster data row by row just one time, and could fit for large image. It, therefore, has high efficiency high speed, and gives good experimental results.
