【摘要】 最佳曝光是航空摄影中急需解决的主要问题之一。本文根据一些基本原理，运用分析法讨论了像差、衍射、曝光量及影像前移对摄影分辨率的影响。从控制动态分辨率的角度出发提出了实现最佳曝光的方法及数学模型。借助于这种方法，可以对系统输出影像的质量进行预测和控制。更多还原

【Abstract】 Determination of optimum exposure is one of the major problems. which needs tobe solued in the air photography. The paper based on some basic theories discusses theeffects of aberration. diffraction. exposure and the image motion to the resolution byanalysis. Starting from the control of dynamic resolution. a method and math rnodelwhich realize the optimum exposure. are presented. With the help of the method. thequality of system output image can be estimated and controlled.更多还原
