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。

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.
