摘要: 根据目标和背景亮度计算公式和3维图形开发包，建立了仿真3维场景。基于仿真场景，对激光动态光束定向系统的跟踪识别过程进行了仿真研究。分析了跟踪、瞄准过程中各种误差的涵义，研究了视场大小、目标成像姿态对跟踪过程的影响，通过头部跟踪顶点滑动误差的理论值与仿真实验值的比较校验了仿真场景的建立与图像处理方法的正确性。研究了头部边缘跟踪算法，仿真结果基本满足了激光动态光束定向系统对跟踪精度的较高要求。

Abstract: 3D simulation scene is obtained according to formulae of target and background luminance and 3D graphics software. Based on the simulation scene, tracking and identifying process of dynamic laser beam pointing system is studied. Several errors in tracking and aiming process and effects of scale and target imaging attitude in the scene on process are concerned. The construction of 3D scene and image process methods are proved correct by comparing simulation results with theoretic results of the tracking error of moving top of head edge. Head edge tracking is studied and enough tracking precise is achieved for laser beam pointing system. -
