| 摘要: |
| 对自然地表分形特征进行了分析和总结,并结合微地形所具有的自然特性,提出了具有方向性分形特征的中点随机位移法。实验结果表明该方法能较好地反映原始数据的总体轮廓,而且还能较好地再现原始微地形的粗糙起伏及各向异性, 因而是一种可行的构造三维地形的插值方法。 |

| Abstract: |
| This paper gives an analysis and summary of the features of the natural terrain, and integrating with the nature trait of tiny terrain,presents a midpoint random displacement method with orientation fractal trait.The result of the test shows that the total outline for original data is preferably generated and rough undulation and anisotropy of the original tiny terrain are preferably reproduced by this method.Thus this is a feasible interpolation method that constructs 3-D terrain. |
