| 摘 要： | 太阳光线被水面直接反射到传感器会造成耀斑污染的现象。高分辨率卫星影像可利用近红外波段消除太阳耀斑。在分析耀斑产生的辐射传输过程的基础上,利用World View-2卫星4波段和8波段多光谱影像设计实验,比较了3种常见的高分辨率太阳耀斑消除算法。结果表明,各种耀斑消除算法的目视效果都较为优秀,定量应用场合下Hedly算法和Goodman算法更有优势。

| Abstract: | Sun glint,the specular reflection of Sun light from water surfaces,is inevitable due to the limitation of imaging circumstance.For high resolution imagery,the near-infrared band can be used to estimate Sun glint radiance.Based on the analysis of Sun glint radiative transfer process,the different types of experiments using 4 bands and 8 bands WorldView-2 multispectral imagery are designed to test three most common high resolution Sun glint correction algorithms.Result shows that all those algorithms are excellent in term of visual effect while Hedly and Goodman are better for quantificational application. |
