摘　　要：装药精度问题一直是影响我国弹药制造技术发展的重要瓶颈,影响战斗部装药精度的误差源有很多,而视觉定位测量误差是所有误差源中影响程度最大的一个。为此提出了一种针对战斗部装药的视觉定位系统,创造性地建立了"两点法"数学模型,并对该定位系统的结构参数进行优化分析。通过建立战斗部装配视觉定位测量系统—双目立体视觉测量系统,对视觉定位系统测量的误差建立"两点法"数学模型,并利用MATLAB进行仿真分析,找到最优的结构参数取值范围,提高了装药装置执行端的定位精度,进而提高了战斗部的装药精度。不仅为我国弹药制造技术的发展奠定了基础,而且对提高战斗部装药的效率和智能化水平具有重要意义。Charging accuracy problem has been an important bottleneck affecting the development of China's ammunition manufacturing technology,there are many error sources affecting the accuracy of explosive w arhead,and visual position measurement error is all error sources in one of the biggest influence. In this paper,a visual positioning system for w arhead charge is proposed,and the mathematical model of ' tw o points method' is established,and the structure parameters of the positioning system are optimized. Through the establishment of w arhead assembly visual position measurement system and measurement system of binocular stereo vision,the vision positioning system of measurement error to establish ' tw o points method ' mathematical model,and simulated by M ATLAB,to find the best value range of structure parameters,improved the loading device perform positioning accuracy of end,and improve the accuracy of drug loading w arhead.Not only laid the foundation for the development of ammunition manufacturing technology in our country,but also has the important significance to improve the efficiency and intelligence level of the w arhead.
