摘要: 面向森林资源调查需求,应用IHS变换融合、主成分变换融合、乘积变换融合和全色锐化融合等4种方法对天绘一号2m全色和10m多光谱数据进行融合,并应用目视判断和数学统计方法对融合后影像进行评判。结果表明:全色锐化融合地物纹理清晰,又具有较好的光谱保持能力,适合于森林资源调查应用。

Abstract: Facing the need of forest resource investigation,we fused the high spatial panchromatic of 2 m and the multispectral data of 10 m by using four methods:IHS transform,principal component transform,multiplicative transform and pansharpening.The fusion images were compared and analysed by using both visual judgments and statistical method.The result indicated that pansharpening fusion image has more clear texture and the best ability of spectral preservation.Therefore,the pansharpening fusion is suitable for the forest resource investigation.

Key words: TH Mapping Satellite-I, forest resource investigation, fusion algorithm, fusion evaluation
