| 摘 要： | 高分一号(GF-1)是我国自主研制的宽幅带高空间分辨率遥感卫星,为分析其在海岸带地区的应用潜力,本文采用主观和客观相结合的评价方法,并与SOPT-5卫星影像进行比对,开展GF-1影像的成像质量评价。主观评价结果表明:GF-1影像表现能力与SPOT-5影像相当,在某些地物特征表现上与SPOT-5比较一致。客观评价表明:GF-1影像的4种统计参数与SPOT-5影像比较接近且各有高低,GF-1影像各波段的灰度分布更分散,地物间的可分性更高;GF-1影像各波段的信噪比和波段间的独立性与SPOT-5比较,基本相同,整体看来,GF-1具有较高的成像质量,在海岸带地区具有一定的应用潜力。

| Abstract: | GF-1 is a wide band of self-developed high spatial resolution remote sensing satellite. To analyze its potential applications in coastal areas and evaluate the its image quality, we used subjective and objective evaluation method and took a compared the SOPT-5 satellite images. Subjective evaluation showed that: GF-1 image and SPOT-5 image had equivalent performance capabilities, and on some land features, GF-1 and SPOT-5 images showed significant. Objective evaluation showed that: Four kinds of statistical parameters of GF-1 and SPOT-5 images were close and had high or low aspects respectively. Each band gray distribution of GF-1 image was more dispersed, and had a higher separability feature. The SNR of each band and the independence between each band in the GF-1 images were basically the same compared with the SPOT-5 images. Overall GF-1 has a high image quality and has some potential applications in coastal areas. |
