Modeling and Simulation of Optical-electronic Observation and Sighting Device Based on Radial Restriction

为研究单兵系统作战演示系统,分析了线性、非线性光电瞄具模型,建立了基于径向约束的光电瞄具标定模型,给出了瞄具所要标定的内、外部参数和标定步骤.对光电火控系统光电瞄具进行了标定,通过编程得到了标定后的光电瞄具的成像,在不同距离射击时对某物体的成像数据与图像进行了计算与仿真.仿真结果表明,利用径向约束的方法能够正确反应光电瞄具的成像.计算结果表明,该模型是可靠的,为进一步研究轻武器火控系统打下了基础.

To research operational demo system of individual soldier system,the model of linear and non-linear optical-electronic observation and sighting device was analyzed;the calibration model of optical-electronic observation and sighting device based on radial restriction was established.Inner parameter,outer parameter and calculation process of the optical-electronic observation and sighting device were given.The calibration of the optical-electronic observation and sighting device was obtained.The imaging data and image of the object was calculated and simulated at different shooting distance.The results show that the model is reliable,and imaging of optical-electronic observation and sighting device can be correctly described by radial restriction.Current research work lays the foundation for further research of fire control system of small arms.
