摘要
在以高速数字摄像机为核心的高精度弹体姿态测量系统中,对炸弹进行姿态测量时,成像光学系统的固有特性使得数字图像存在畸变。根据像差理论建立了三次多项式的畸变校正模型,分析比较了不同的灰度重建方法的优缺点,进行了三次卷积法的灰度重建,并进行了仿真实验。校正后的图像可用于高精度的弹体姿态测量。
In the high-precision missile body attitude measurement system with a high-speed video camera as the core component, the digital image may have distortion when measuring the missile attitude because of the inherent characteristics of the imaging optical system. A distortion correcting model of cubic polynomial was built up based on primary aberration theory. The gray scale reconstruction was implemented based on cubic convolution after analyzing the advantages and defects of different interpolation methods, and simulations were made. The corrected image can be used for high precision missile body attitude measurement.
