摘要
根据西宁市城区扩展监测对遥感信息提取的需要,采用多种方法将具有较高空间分辨率的SPOT遥感图像和具有多波谱的ETM+遥感图像进行增强及融合试验,结果表明:对ETM+影像先进行锐化处理,再将SPOT影像与锐化后的ETM+信息融合,然后对融合后的影像进行去霾处理得到的影像质量最好。
Based on the demand of extracting remote sensing information for monitoring the urban area expanding of Xining city, some methods were used for image enhancement and fusion by using SPOT high spatial resolution remote sensing image and ETM ＋ multi - spectral remote sensing image. The results showed that the best method is firstly sharpening the ETM ＋ images, secondly implementing the image fusion for the sharpened ETM ＋ images and SPOT image, then hazing the fused image.
