研究河流和湖泊的矢量目标匹配方法在地理空间变化检测、地图更新等方面具有重要意义.文中提出一种计算线线部分匹配的折线集的算法,基于该算法和面面叠置率,研究河流和湖泊的面面、面线、线线1∶1匹配算法和非1∶1匹配策略,实现河流和湖泊整个目标数据集的匹配.实验表明,文中所研究的算法和策略具有两个优点:解决了面与线在不相交情况下的匹配问题;对数据误差有很强的适应性.%It is important to study the vector object matching method of rivers and lakes in geospatial changing detection and map updating.In this paper, an algorithm on calculating the polyline set in partly matching of line to line is put forward, and based on this and area to area overlay rate, the one to one matching algorithm for area to area, area to line and line to line, and tactics of not one to one matching for rivers and lakes are presented.The matching of the whole dataset of rivers and lakes can be realized.The experiments show that the algorithm and tactics in this paper has two advantages: a.the matching can be resolved when an area does not intersect with a line;b.it has a great adaptation to data error.
