摘　　要：航空光电成像载荷作为一种有效的侦察装备,由于光学系统灰尘、探测器坏像元、探测器非均匀性等因素,导致光电成像载荷生成的图像中存在固定噪声,从而使载荷的成像质量下降。为解决该问题,文中提出一种可以去除航空光电成像载荷系统固定噪声的方法。首先使用光电成像载荷对标准光源进行成像,得到标准图像;再对标准图像进行处理,得到固定噪声图像;最后从待优化图像中将固定噪声图像剔除,得到去噪后图像。实践证明,该方法在保持图像空间结构信息以及不损失图像细节的前提下,可以有效地去除光电成像载荷的系统固定噪声,提升光电成像载荷图像质量。As an effective reconnaissance equipment,aerial photoelectric imaging load,due to the factors such as dust on the optical system and unqualified pixels and the non⁃uniformity of the detector,can lead to the presence of fixed noise in the image generated by the photoelectric imaging load,which can degrade the imaging quality of the load.Therefore,a method that can remove system⁃level fixed noise from an aerial photoelectric imaging load is proposed.A standard light source is imaged by photoelectric imaging load to obtain a standard image,which is processed and then a fixed noise image is obtained.The fixed noise image is removed from the image to be optimized to obtain a denoised image.It is proved that the proposed method can effectively remove the system⁃level fixed noise of the photoelectric imaging load and improve the image quality under the premise of maintaining the spatial structure information of the image and not losing the image details.
