摘要
骨架是线状对象的一个重要特征,如何快速地提取骨架线是研究图像图形学的一个重要方向.为了快速地提取线状地物的骨架线,通过分析其与Voronoi图之间的异同点,提出了一种基于Voronoi图快速提取线状地物骨架的方法,并针对不同的边缘采取了不同的方案以保证提取的骨架线的准确性,最后以福州市区内闽江部分河段的骨架提取为实例检验了该方法的有效性,并分析了存在的问题,提出了改进的方向.
Skeleton is an important character in linear feature. How to extract the skeleton rapidly and accurately attracts many experts＇ attention . In order to extract the skeleton of linear feature quickly, by comparing the difference and relationship between the skeleton and Voronoi Diagram, a method which designed to attain the skeleton of the linear feature based on the Voronoi Diagram is put forward. The validity is testified through a case study in which the skeleton of a part of Minjiang river in Fuzhou has been extracted by the method, and its disadvantage is also analyzed.
