摘要
通过对光学望远镜瞄准原理的分析,根据望远镜放大倍数与焦距以及视场角的数学公式得到了三者之间的联系,由计算机图形学透视投影原理建立了瞄准的仿真模型,提出了一种基于Vega的瞄准镜视景仿真的实现方法,介绍了该方法实现的关键步骤,最后给出了部分程序源代码和仿真效果图。该仿真模型与实际系统光学原理完全一致,增强了仿真系统视觉效果逼真性和瞄准原理的准确性。由于该方法在工程上极易实现,因此它对于此类视景仿真具有通用的借鉴作用。
In this paper, after analyzing the principle of optical telescope aiming, on the ground of perspective projection theory of computer graphics, an aiming simulation model is built according to the relationships among magnification factor, focal length and field angle, which are developed form their math formulae. The implementation of sighting telescope＇s visual simulation is proposed. The key steps of this implementation are presented. And at last, some programming source codes and simulation effect pictures are listed. The simulation model runs in the same way as the real system on the optical theory in this method, thus enhancing the fidelity of visual effects and veracity of aim principle. It is so easy to implement in project that this approach can be used universally in such visual simulation,
