摘要
为了研究气压对车载光电系统成像质量的影响,在分析气压变化对光电系统离焦影响的基础上,建立了气压引起光电系统成像模糊的数学模型。通过建立某轮式火炮瞄准镜的光学系统模型,并设置不同的环境气压对系统模型进行仿真分析,最终得到了不同气压下该瞄准镜的成像仿真图像。利用灰度平均梯度法对仿真图像进行评价,并得出结论:环境气压越低,图像越模糊,该瞄准镜的成像质量越差。此研究对新型车载光电系统的环境适应性设计具有重要的参考价值。
Abstract
In order to study air pressure influence on imaging quality of vehicle-mounted photoelectric system,a mathematical model of air pressure leading to image blurring of photoelectric system was established based on the analysis to the influence of air pressure variation on defocusing of photoelectric system.Optical system model of a certain type of wheeled artillery sight was established,the simulation analysis of system model was carried out by setting different ambient air pressure,and simulated images of the sight under different air pressure were obtained finally.Simulated images were evaluated by using gray mean gradient,and the conclusion was summarized: the lower the air pressure,the more blurred the image,and the worse the imaging quality of the sight.The study is of great reference value to environmental adaptability design of new type vehicle-mounted photoelectric system.
