【摘要】：通过对现有高光谱数据图像质量评价方法的研究,选取辐射精度、信息熵、信噪比、清晰度等图像质量评价指标对THEMIS-T-FPS2500地面高光谱成像仪采集的数据进行了数据质量评价。结果表明,THEMIS-T-FPS2500地面高光谱成像仪数据256个波段中从第200波段开始,图像的信噪比较低,图像清晰度较差;第1个~10个波段的信噪比虽然较高,但图像清晰度较差,剩余的190个波段的数据成像质量较好,目标物清晰,信息量丰富。
[Abstract]:Based on the research of the existing methods of image quality evaluation of hyperspectral data, the data quality of THEMIS-T-FPS2500 ground hyperspectral imager is evaluated by selecting the image quality evaluation indexes such as radiation accuracy, information entropy, signal-to-noise ratio, clarity and so on.The results show that in 256 bands of THEMIS-T-FPS2500 data, the signal-to-noise ratio (SNR) of the image is low and the resolution of the image is poor from the 200th band, and the SNR of the first ~ 10th band is relatively high, but the definition of the image is poor.The remaining 190 bands have good imaging quality, clear object and abundant information.
