摘　　要：随着虚拟现实与仿真技术的发展,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。通过对单目视觉测量方法和四点定位模型的分析,论述了图像式头盔瞄准具的系统结构及工作机理,着重讨论了定位模型方程解的结构以及错误解的排除等关键问题。设计了头盔瞄准仿真平台,使用VC开发环境与Open-GL相结合导入3dmax模型,设置投影模型参数与相机标定参数一致,仿真相机成像过程,完成了系统组成结构和工作过程的仿真与模拟。仿真实验证明该模型能够完成目标的精确定位,可供从事头盔瞄准具设计和系统综合的工程师参考。With the development of virtual reality and simulation technology,helmet targeting technology is used more and more widely in fighter aircrafts and helicopters for ground training and actual operation.The construction and working principle of image-based Helmet-Mounted Sight（HMS） are discussed here with detailed analysis on monocular vision measurement and 4-point positioning model.After that,the structure of the solution for positioning function and how to eliminate the fault solutions are presented.A platform to carry out simulation of the HMS system was built up,and 3dmax model was loaded with OpenGL in VC development environment.The imaging process was simulated by setting project model parameters in accordance with camera.Simulation experiment showed that the model can implement precise target locating,which may supply a reference for HMS design and system integration.
