Simulation Method of Dynamic Reconnaissance Environment Based on GE and SU Model

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.
