【摘要】：以中国南海东岛周边海域为研究区域,利用波段组合法开展高分辨World View-2影像的水深探测能力研究,分别建立单波段、双波段和多波段模型,进行精度评价。结果表明:多波段模型反演效果最好,双波段次之,单波段最差;各波段水深探测能力比较:绿波段㧐全色波段㧐蓝波段㧐红波段;前视影像比后视影像的水深反演精度略高,全色波段在水深探测中具有重要作用。
[Abstract]:Taking the waters around the East Island of the South China Sea as the study area, the bathymetric detection capability of high-resolution World View-2 images was studied by using the band combination method, and the single-band, two-band and multi-band models were established, respectively. The result shows that the inversion effect of multi-band model is the best, that of double band is the second, and that of single band is the worst. Panchromatic band? Blue band? The accuracy of water depth inversion of forward image is higher than that of backward image, and panchromatic band plays an important role in water depth detection.
