| 摘 要： | 以黄河口典型滨海湿地为实验区,采用主客观评价相结合的方法,在与SPOT-6卫星影像对比的基础上进行了GF-2卫星全色影像、多光谱影像以及融合影像的质量评价。目视主观评价表明,GF-2影像在滨海湿地地区整体表现能力上与SPOT-6影像相近,地物边界、纹理等细节信息方面优于SPOT-6影像;基于统计指标的客观评价结果显示,GF-2影像受噪声干扰的程度小于SPOT-6影像,承载的信息量与SPOT-6影像接近,多光谱影像以及融合影像各波段间的独立性也与SPOT-6影像相当,但在灰度、离散程度和地物可分性上与SPOT-6影像还存在一定的差距。

| Abstract: | In order to analyze the imaging quality and application potential of GF-2 in coastal wetland areas,the subjective and objective evaluation methods are used to evaluate the imaging quality of the panchromatic,multi-spectral,and fusion images of GF-2 satellite in comparison with SPOT-6 satellite images.The subjective evaluation shows that the overall performance ability of GF-2 images is close to that of SPOT-6 in coastal wetland areas,while the detail information like object boundary and texture is better.The objective evaluation results show that the dagree of the noise interference of GF-2 images is less than that of SPOT-6 images,the amount of information carried by GF-2 images is close to that of SPOT-6 images,and the independence between the various bands of GF-2 images is basically equivalent to SPOT-6 images,but the band gray distribution of SPOT-6 images is more dispersed,and has higher separability. |
