摘　　要：为除去遥感影像的辐射不一致性、条带噪声等辐射问题,反映影像真实地物信息,为遥感图像的识别、解译提供便利,基于统计策略、直方图匹配方法和改进的遗传算法,提出遥感影像相对辐射校正算法,并将生成模型应用于遥感图像数据进行实验。实验结果表明,相比传统校正方法,这种创新的算法设计更加自动化、通用,相对辐射校正效果显著。The goal of this paper is to remove the radiation problems such as inconsistency and band noise of remote sensing images,reflect the real ground object information corresponding to the images,and provide convenience for the recognition and interpretation of remote sensing images.Based on statistical strategy,histogram matching method and an improved genetic algorithm,a remote sensing image relative radiation correction algorithm is proposed.Apply the generative model to remote sensing image data for experiments.Experimental results show that,compared with traditional correction methods,this innovative algorithm design is more automated and versatile,and the relative radiation correction effect is advanced.
