摘要
图像融合是目前广泛应用的一种增强图像信息的技术手段 ,其目标是将不同几何和不同质的图像通过某种数学和物理变换生成相同几何或另一种均质的新图像。以引大灌区土地利用调查为例 ,针对灌区的土地类型特点以及对空间分辨率的要求 ,选择 SPOT全色波段和 TM多光谱波段 ,利用 Brovey图像融合方法进行图像融合 ,以获得 1 0 m空间分辨率的假彩色合成图像。同时 ,对融合的图像进行精度验证 。
Image fusion is one of widely used techniques to enhance image information of re mote sensing, which could be used in different geometric and quality images to g enerate a new image with same geometric feature and quality by transform of math ematics and physics. The investigation of land cover in Yinda irrigated region w as selected as cast site. According to the characteristics of land types and the requirement of spatial resolution of the investigation, panchromatic Spot image and multi-spectral TM image were used to generate new false color composite ima ge with 10m spatial resolution by using Brovey image fusion. The precision of im age was analyzed and tested. The results show that the fusion image could meet t he demand of application.
