摘要:

在栅格数据矢量化过程中,对“岛”状图的处理一直不够理想,特别是对于有相邻关系“岛”的情况。针对这个问题本文给出一种栅格数据矢量化方法,对含有相邻关系“岛”的情况有较好的处理效果,并通过实验证明该矢量化方法的有效性。

Abstract:

In the process of vectorization, the “island”like map is inadequate to deal with vectorization of raster data, in particular for the relationship between adjacent “islands” of the situation. In this paper, a novel method of vectorization is put forward. This approach can better deal with the relationship with the adjacent “islands” of the situation. Finally, the experiments prove the effectiveness of the method of vectorization.
