摘要
提出一种利用薄板样条函数实现地图矢量化处理的方法。通过对地图图像进行轮廓提取、追踪,获取边界线的特征点,运用薄板样条函数拟合曲线,最后,通过与克里金插值法的实现效果进行对比,证明薄板插值是有效的插值方法。
In this paper,a method using thin-plate spline function to achive map vectorization process was put forward, of boundary Finally, the Through the process of contour extraction, contour tracking, and acquisition of feature points of the map image, and using thin-plate spline function, the curve fitting was completed method was proved effective in contrast with the implements of Kirging method
