摘要
通过介绍在MAPGIS环境中实现数字地图拼接的理论和方法,阐明了拼图过程按多项式拟合法进行误差纠正与按正交旋转矩阵进行线性变换的本质区别,对MAPGIS软件整图变换功能技术内幕进行了深入研究,同时从数字拼图的几何原理出发,勾绘出拼图过程中所涉及的数学模型以及算法模型,最后通过程序设计语言源代码给出具体的实现方案。
After a introduction to the theory and method of realizing digital map - joining onMAPGIS platform, two methods of map - joining, i.e., polynomial fitting and ortho - lineartransformation have been expounded. The core of entire - map transformation technique was thoroughlydescribed. From the geometric principle of digital map - joining, the related mathematics model andalgorithm model were illustrated. At last, the conrete enforcement plan was given by programminglanguage.
