摘要： 在传统无人侦察机模拟训练方法中，视景仿真环境逼真度不足，三维地形容易忽视动态目标。为此，提出一种基于谷歌地球(GE)和SketchUp(SU)模型的动态侦察环境模拟方法。通过GE场景建立三维仿真环境，利用SU制作三维模型，采用三次B样条插值方法对路径进行平滑处理，计算模型的姿态角，使用Keyhole标记语言和GE COM API，完成飞行视景仿真。实验结果表明，该方法能生成逼真的动态三维场景，减少建模工作和开发周期。

Abstract: In order to solve the difficulties of traditional simulation training method on unmanned reconnaissance aircraft, such as the low environment fidelity, ignoring dynamic target in 3D terrain, this paper proposes a simulation method of dynamic reconnaissance environment based on Google Earth(GE) and SketchUp(SU) model. It produces the 3D simulation environment based on GE and the 3D model through the SU, adopts cubic B-spline interpolation method to smooth the path, and calculates models’ attitude data as well, completes flight visual simulation through the method of Keyhole Markup Language(KML) and GE COM API. Experimental results show that this method can generate a realistic dynamic 3D scene, and reduce the amount of modeling work and the development cycle.

Key words: simulation training, Google Earth(GE), 3D model, dynamic target, cubic B-spline interpolation
