自适应的三维分形地形重建算法研究*

针对常规三维分形地形重建算法具有的速度慢、插值点分布不均匀、参数设置复杂等缺点，提出自适应的三维分形地形重建算法。该算法根据地形的起伏特征自动确定垂直压缩因子，根据子域面积进行均匀插值。实验结果表明，该方法插值效率更高，所获得的插值曲面更加真实，与常规分形插值相比具有一定的优越性。

Adaptive 3D fractal reconstruction algorithm of terrain profile

This paper presented an adaptive 3D fractal reconstruction algorithm to overcome the shortcomings of conventional methods, such as time consuming, ununiformity, parametric complexity. The proposed algorithm could automatically determine the vertical scaling factors according to topographic patterns. The area of subdomain was taken into consideration in the process of interpolation to make the added points uniform. The experimental results indicate the new algorithm is superior to conventional fractal interpolation for high efficiency and fidelity.
