摘要
针对在虚拟战场环境仿真中构建大规模地形,现有的计算机硬件条件无法进行实时处理,本文提出了一种对特征点用线性约束能量最小化方法反算控制点;用三次准均匀B样条曲线插值特征点生成B样条曲线,最后利用线动成面的原理生成B样条地形曲面。其中对偏差较大点通过增加新特征点的方法进行了自动修复。通过对实际高程数据值插值地形进行实验,得出运用该方法拟合的地形图更精确、更逼真。该算法主要用于对地形中重点关注区域进行地形重构,以提高局部地区的分辨率和逼真度。
Construction of a virtual battlefield simulation for large-scale topography,the existing condition of computer hardware can not be real-time processing,,a feature point using the linear constraints on energy minimization method of inverse control points was proposed.With three quasi-uniform B-spline curve interpolation feature points generated B-spline curve,and finally moving into the surface using the principle of line generated B-spline surface topography,which points to the larger deviation of feature points by adding a new auto repair.Through interpolation of the actual terrain elevation data values were obtained by experiments using this method more accurate fitting of topographic maps and more realistic.This method can be used to focus on the large terrain topography reconstruction region,to improve some areas of resolution and fidelity.
