摘    要:提出一种基于双三次B-样条的DEM地形数据重构算法.根据用户对不同地形区域关注程度的不同而采用不同的地形分辨率,可有效地降低计算机负荷.采用该算法可以有效地对关注度较高的区域进行地形重构,提高该区域的地形分辨率.实践结果表明,该算法满足大地形视景仿真系统的需要.

关 键 词:B-样条  地形重构  视景仿真

Abstract:A terrain reconstruction algorithm of DEM datum is proposed based on bi-cubic B-spline interpolation according to attention difference of terrain area,and using the multi-resolution terrain model can lighten computer load,process terrain reconstruction to attention area,and improve the resolving power.The experimental results indicate that this algorithm is practical and applicable.
Keywords:DEM
