摘要
模拟在测绘过程中被忽略的地形细节对逼真地形重建来说是十分重要的。本文提出了一种基于从原始观测数据提取的分形特征的快速自适应分形内插方法。所介绍的内插模型是对ｆＢｍ的一个局部稳态的近似，由此产生的几何纹理细节不论在视觉上还是在精度上都更接近真实地形。
To model the lost small terrain details during surveying and mapping is very important to realistic terrain reconstruction.This paper describes a fast abaptive fractal interpolation technique based on the fractal features extracted from the raw DTM.Since the stochastic midpoint displacement model introduced by the authors is a locally stationary approximation to fBm,it can produce more visual acceptable and more accurate geometric texture details.
