摘要
通过分析光学系统的特性,利用点扩展函数,提出了用图像斑点的几何尺寸推算红外点源辐射强度比的方法。通过本方法对多帧因自动增益控制和成像设备饱和而受损的红外图像分析表明,红外辐射强度比的计算值和理论值是吻合的,证明了该方法的有效性。
After analyzing the features of the optical system, this paper, based on the point spread function, proposes a method to calculate the infrared radiant intensity ratio by means of the spot size of the corresponding point. With this method, many infrared images spoilt by AGC and equipment saturation are tested, and the calculated values of the infraced radiant intensity ratio are coin-cient with the theoretical ralues, which proves the effectiveness of the method.
