| 摘 要： | 根据地理信息系统中路径设计的需要,对已有的三维路径设计方法进行了概括,提出了两种三维路径生成法概念,并对其做了简单的比较。为了得到沿路径连续的飞行或运动,两种路径生成法都必须对路径进行拟合。论文重点论了张力样条在路径光滑处理中的有关问题,如张力样条的构造、求解以及规范化张力系数对路径外貌和光顺性的响,并用实验加以证实,其结果有较好的实用价值。

| Abstract: | This paper sums up two design methods of3D path and puts forward two concepts of design method of3D path for the need of path designing in GIS,and briefly introduces the differences of two methods.For continuity of flying or moving,both methods have to get fitting curves.This paper emphasizes to discuss problems of application of tension spline in3D path smoothing.such as forming and solving the function of tension spline,and discussing the influence of standardizing tension coefficient on shape and smoothing of path,also proves by experiments.The results have preferable applied importance. |

| Keywords: | control point path smoothing property curve fitting tension spline tension coefficient |
