摘要
基于Hedley等的方法对WorldView-2遥感影像反演岛礁水深时的太阳耀斑进行去除,在技术实现过程中根据WorldView-2波段设置的特殊性做一定的改进,将8波段分为两组,其中蓝、绿、红波段依据近红外1波段来去耀斑,海岸、黄、红边波段依据近红外2波段来去耀斑,在具体应用中完整实现该理论方法。结果表明,去耀斑后无论是对水深反演结果的精度上还是从影像直观视觉上都有提高,该方法有利于WorldView-2影像处理中耀斑去除的常规化应用。
The method of Hedley et al. was applied in the World View-2 remote sensing image inversion reef water depth. Certain improvement was made according to the particularity of World View-2 band set in the process of technical implementation, and 8 bands were divided into two groups. For sun-glint removal, the NIR1 band was used to estimate water surface properties in the blue, green, and red bands, and the NIR2 band similarly was used for the coastal, yellow, and red-edge bands. The theory method was implemented completely at some specific applications. Result shows that there are a substantial visual improvement and the improvement of water depth retrieval precision. The practical approach described here will hopefully expedite the routine adoption.
