针对电离层远紫外遥感的O/N2 反演图像质量评价应用，以GUVI网站发布的图像为参考，分别从RGB和HSV两种颜色空间对获取的远紫外O/N2 图像的反演质量进行了对比分析。利用RGB颜色空间的评价函数和HSV颜色-空间直方图相交匹配的方法评价了反演图像与参考图像间的相似程度，待评价图像与参考图像之间具有较高的一致性。结果表明，从图像的角度评价远紫外遥感热层O/N2 图像的反演质量是切实可行的。

To assess the quality of the retrieved O/N2 images from FUV remote sensing, the retrieval quality of the obtained FUV O/N2 images is analyzed in RGB and HSV color spaces respectively when the images published at the GUVI website are used as the reference images. The similarity of the retrieved images to the reference images are assessed by using the evaluation functions in the RGB color space and the HSV color-space histogram cross matching method. The images to be assessed are highly consistent with the reference images. The result shows that it is feasible to assess the retrieval quality of O/N2 images from FUV remote sensing in the view of images.
