摘　　要：虚拟测试场景的可视化仿真是经纬仪室内性能测试的重要手段。构建了虚拟测试场景仿真系统总体结构,该系统主要为虚拟测试提供三维虚拟场景和场景仿真图像。论述了虚拟场景仿真中基于目标运动特征的轨迹、姿态建模方法及背景云图模拟技术,图像仿真时目标姿态扰动模拟、灰度模拟及目标、背景图像实时合成等关键技术。采用VC++和OpenGL,开发了经纬仪虚拟测试场景仿真系统,应用表明,生成的三维场景、合成出的目标、背景图像及数据有效满足了经纬仪相关性能的测试需求。Virtual test scene simulation is an important method for testing capabilities of optoelectronic theodolite system in the lab. A general function structure of the virtual test scene simulation system was established. This system mainly provides the virtual scene and simulation image for virtual test. Methods of the virtual target track modeling and the target pose simulation for the target motional characteristics, and the background cloud simulation in the scene simulation were proposed. Moreover, the target pose interference, the noise influence and the grey distribution were discussed in the scene image simulation. This simulation system was developed by the combination of VC＋＋ and OpenGL. Simulation tests show that virtual test scene and the synthesis image of the target and background are effective in testing tracking capabilities of theodolite.
