摘要
以洪雅县柳江镇为试验区,选用SPOT-5全色影像和多光谱影像为材料,采用PCA、Brovey以及IHS变换融合方法,对SPOT-5全色与多光谱图像进行融合处理,为退耕还林工程面积监测奠定基础。通过对各融合结果图像进行主观和客观的综合评价,得到评价结果:Brovey变换融合方法得到的结果图像在其空间质量和光谱质量综合表现的最好,适宜于低山丘陵区的遥感监测使用。
With the SPOT-5 and multi spectral images of Liujiang Hongya county town as the materials, using the fusion method of PCA, Brovey and IHS transformation, this study carried out a fusion treatment of the SPOT-5 and multi spectral images, which lay the foundation for project monitoring of conversion of cropland to forest. Then subjective and objective evaluation was given to the research results. The evaluation results showed that the spatial and spectral quality of the images obtained from the Brovey transforming fusion method was the best,appropriate for remote sensing monitor of hilly areas.
