摘要
针对扫描地图矢量化过程中对交叉、粘连地图要素自动提取困难的特点,提出了一种基于拆分—组合的地图要素自动提取方法,对该方法的各个步骤进行了设计,并对其中关键的细化处理方法进行了优化研究,验证了该方法的有效性。
During the vectorization of scanned map, it is difficult to extract the crossing and conglutinating map elements automatically. Aiming at this characteristic, an automatic extraction method for map elements based on splitting and combining was proposed. This paper also designed each step of this method, studied the optimization of the key technique about thinning and tested the validation of the method by programming.
