摘　　要：研究飞行员头盔控制问题,头盔瞄准技术越来越多地应用于战斗机和直升机地面飞行模拟训练和实际作战。为了使目标瞄准线转为控制信号,实现目标识别的准确性,提出通过对单目视觉测量方法和四点定位模型采用图像式头盔瞄准具的系统结构及工作机理,实现定位模型方程。结合当今虚拟现实与仿真技术,设计并开发了头盔瞄准系统仿真平台。在VC开发环境中导入三维模型,调用OpenGL函数设置投影模型参数与相机标定参数一致,实现了摄像机成像的仿真过程,完成了图像式头盔瞄准系统工作过程的仿真,实验结果证明模型能够完成目标的精确定位,开发平台可为系统设计和系统综合设计提供参考依据。Helmet targeting technology has been used more and more in fighter aircraft and helicopters on the ground training and actual combat flight simulation.Under more and more observations,experiment and product prototype cost much money.An in-depth investigation into the mechanism of helmet-mounted sight（HMS） based on monotone photogrammetry techniques is reported,the aiming model with 4 points is analyzed in detail.Combing virtual reality with simulation technology,the platform is constructed to carry on the simulation of the HMS system,loading 3D model with OpenGL in VC development environment.The imaging process is simulated by setting project model parameters in accord with camera.The model is evaluated with experiments for practical use in aiming accurately.This article may provide help for understanding,designing and improving the HMS system in some extent.
