摘要
提出了一种基于面积最大内接四边形的图斑自动数字注记方法,并给出了该标注方法的理论推导与实现过程,解决了目前不规则凹多边形图斑注记质量不好的现状,经山西大土河光明村图斑测试,证明这种方法标注质量好,效果显著。
This paper proposes a method of polygons automatic digital annotation based on the maximum area of the inscribed quadri- lateral. It also gives the theoretical derivation and the implementation process of the method. This method solves the problem that the annotation quality of irregular concave polygons is poor with current annotation method. It is proved that this method has higher quality in polygons annotation based on the test at Guangming village in Shanxi Datuhe.
