基于Quickbird影像的耕地变化监测中影像融合处理方法研究

Discussion on the Selection of Quickbird Image Fusion Methods in Cultivated lL and Use Change Monitoring

遥感影像预处理是一切工作的前提。以两期快鸟影像为例,以成都市郫县古城镇为研究区,分析了影像预处理中的融合技术。探讨耕地变化监测中影像融合方法选择问题。分别用相同传感器的相同时相的全色波段影像和多光谱影像进行融合,以及不同时相的全色波段和多光谱影像进行融合,得出三个结论。为耕地变化监测中影像融合处理方法问题提供一些好的建议。

Remote sensing image preprocessing is the premise of all the work.Two Quickbird images is used to analyze the fusion technology in the image preprocessing,and discussed the methods selection problem of image fusion in the cultivated land use change monitoring in Gucheng towns of Pixian.The same sensor and the same phase panchromatic image and multispectral image are used to fuse,and used the different phase of panchromatic and multispectral image to fuse,and summarized three conclusions.some good suggestions is provided to the image fusion in cultivated land use change monitoring.
