摘要：

3D seabed terrain is established by the improved fractal interpolation algorithm. By adopting moving surface idea and making use of the local self-similarity of seabed terrain, this method maps rectangular subfield which consists of the cells around the centre interpolated cell to the interpolated cell by using fractal interpolation. In the seabed terrain establishment process, elevation is used to calculate vertical scale factor creatively in this paper. The results show that seabed terrain which is established by this method has high precision, good stability and good sense of reality. Besides, data partitioning and smooth edging is unnecessary so that the complexity of this method is greatly reduced.
