摘要
线要素化简一直是自动制图综合中的重要研究内容。利用小波分析的多分辨率原理和Douglas算法,对线状要素进行平滑和综合,实现了线状要素的空间多尺度表达。并对实际数据进行实验,结果表明,此方法不仅能够达到曲线化简的目的,而且能够保持化简前后的视觉效果和原始数据的特征。
Simplifying linear elements is always the important research in automatic drawing generalization.With the principle of multi-resolution analysis and Douglas algorithm,linear elements have been smoothed and synthesized and finally linear element spatial multi-scale expression is realized.The results show that this method can not only achieve the purpose of simplifying the curve but also maintain visual effect and the characteristics of linear elements before and after simplification.
