针对三维不规则军标与三维地形的匹配问题,对于不规则军标,提出一种基于简化的控制点的地形匹配方法,可以既满足实时绘制的要求,同时又达到绘制效果逼真,较大地提高绘制的速度和效率,该算法通过对标绘中获取的高程曲线进行控制点求解、简化,并和地形数据进行交互平滑等计算处理,生成的曲线更加光滑、合理,通过实验分析验证了该算法的可行性,该算法可以在保证较好的匹配效果同时实现更快速的匹配速度。

A terrain matching method was proposed based on a simplified control point, which could not only satisfy the requirements of real-time rendering, but at the same time, achieve realistic rendering effects, and greatly improve the rendering speed and efficiency of the algorithm for plotting to obtain the elevation curve control points solving, smooth computing, and the resulting curve is more smooth and reasonable. The experimental analysis verifies the feasibility of the algorithm, and the algorithm can achieve better balance between real-time matching speed and matching effect.
