摘　　要：从影像整体质量、局部纹理特征、影像融合和地物类型识别效果等几个方面对资源一号(ZY-1)02C卫星全色/多光谱(P/MS)影像进行评价,并与同时相、同地域的HJ-1CCD影像进行比较,结果表明:ZY-1 02C多光谱影像辐射精度、信息量、信噪比、清晰度及部分纹理指标均优于HJ-1CCD;以图像融合方法Gram-Schmidt和Pan-sharp对ZY-1 02C全色影像与多光谱影像融合,在提高空间分辨率的同时可很好保留影像原始信息;采用ZY-1 02C多光谱及其融合影像对进行地物类型识别的总体精度较高;该影像在国土资源调查、国家重大工程等多方面具有广泛应用前景。This paper evaluated the ZY-1 02Csatellite panchromatic/multispectral(PAN/MUX,P/MS)image from four aspects,the quality of the whole image,texture feature of partial image,image fusion and land type identification effect.This is compared with HJ-1CCD image of the same area at the same time.The results show that ZY-1 02C MUX image is superior to HJ-1CCD image in radiation accuracy,information content,signal-to-noise ratio,clarity and some texture indicators.Fusion of ZY-1 02CPAN image and MUX images by Gram-Schmidt and Pan-sharp method can well retain the original image information at the same time of improving the spatial resolution.The overall identification accuracy of land type by ZY-1 02C MUX image and its fusion image is high.This image has broad application prospects in the land resource survey,major national engineering, and other fields.
