遥感影像数据融合方法应用研究

摘要

介绍了遥感影像数据融合中常用的三种方法：主成份变换法、乘积变换法、比值变换法。以某地区的 SPOT 和 TM遥感影像为实验数据，选用 ERDAS 软件平台，采用数据融合的三种方法分别进行融合实验，对融合的效果和应用进行了对比和分析。实验结果表明：应用不同的融合方法可以得到不同的融合效果，多源遥感影像融合不仅可以提高图像的清晰度，还可以使得提取的信息量更加丰富。%The paper introduced three kinds of commonly used methods,principal component analysis,multiplicative and Brovey trans-form.Using the SPOT and TMremote sensing images of the area as experimental data and based on the ERDAS software platform,the study conducted the fusion experiments with the three methods,and compared and analyzed the effects and application of the fusion. The experimental results showed that different fusion methods could get different fusion effects,and multi -source remote sensing image fusion could not only improve image clarity,but also make the information extracted more abundant.
