中心阵列法实现面状地图要素的自动注记

Automated name placement of area map feature by center array method

本文阐述了中心阵列法进行面状要素自动注记的原理、多边形预处理算法、求取阵列旋转中心的方法和求取注记定位线的算法。另外,还对中心阵列法进行了验证其可行性的试验,其结果证明这种算法不但能够处理所有常规形状的多边形,而且能够适应一些不规则特殊形状的多边形的注记。

The paper mainly expounds the principle of automatic name placement of area element by center array method,the algorithm of polygon pretreatment,the method of getting array rotating center and the algorithm of name placement positioning line.Then,an experiment,made to test the feasibility of center array method,proves that it can deal with not only all polygons with general shape,but also some irregular polygons with special shape.
