利用多边形格网上的拓扑关系 ,可以将对单个多边形的扫描转换扩展到多边形格网上 ,使扫描过程同时对格网中的多个多边形进行 ,减少了转换过程中的求交和扫描线转换次数 .基于上述思想 ,文中对多边形格网上的图像分块处理提出了一种通用的快速算法 ,分析了该算法与逐多边形扫描转换在效率上的差异 .最后 ,介绍了该算法在高精度图像纠正中的一个应用实例-Using polygon the topological relationship on the net, can be expanded to a single polygon scan conversion to the polygon, the Internet, make the scanning process multiple polygons in the grid at the same time, reduce the intersection in the conversion process and the number of scan line conversion. Based on the above ideas, this paper polygon s online image block processing this paper proposes a fast algorithm of gm, and the algorithm is analyzed by polygon scan conversion of the differences in efficiency. In the end, this paper introduces the application of the algorithm in the high precision image correction of an application example
