【摘要】 TM影像的专题信息提取以及最佳合成方案的选择,一直是遥感应用研究领域一个需要深入探讨的课题。其中,对图像色度的定量计算和定量预测以及与此有关的最佳合成方案的确定,目前还没有一个完整的标准和规范可供遵循。 本文,利用TM影像,采用分层曝光方法,讨论了TM影像专题信息提取规范化问题,提出了定量计算色差的方法及合成方案优选的理论,并给出了相应的数学模型。更多还原

【Abstract】 The extraction of thematic information from TM images and the selection of versions of optimal composition material have been a subject which needs a deep research in the fields of remote sensing application. But so far there is no set of complete norms and standards to be followed, especially in the quantitative calculating and estimating of colorimetry on image, and in the determination of optimal composition.The problems as mentioned above are studied more deeply by means of traditional multiple exposuring TM image of experiment area, Shuang yang County in Jilin Province. As the standardization of thematic information extraction from TM images is concerned, this paper proposes a theory of optimizing various composition versions by a method of quantitative calculating colour difference, and gives corresponding mathematical model.更多还原
