摘要: 珊瑚礁区水深反演对于珊瑚礁区域工程建设与珊瑚礁保护具有重要意义。遥感影像辐亮度值与水深具有很好的相关性,据此波段比值法和线性组合算法被应用到珊瑚礁区的水深反演中,并根据复杂的珊瑚礁地形地貌对以上2种模型均做了优化。结果表明:经过改进的波段比值算法在3~5 m、10~15 m的水深反演中精度较高。而本文用到的模型在5~10 m水深范围内的精度均较差,初步得到的结论是珊瑚礁区特殊的地形地貌导致的。 关键词: 珊瑚礁; 黄岩岛; 水深反演; 波段比值算法; 线性组合算法 Abstract: Water depth inversion is of great important to coral reefs’ protection and engineering construction of the coral reef region.As the correlation between the remote sensing radiance and the water depth is a very well,so the band ratio transform and the linear combination transform were adopted to the water depth inversion around coral reefs.Based on the complex topography of coral reefs,these two algorithms were optimized for the water depth inversion.Finally,our experimental results show that the improved ratio transform was suitable for retrieving water depths among 3~5 m and 5~10 m.While none of the models that mentioned in this paper performed well in water depth of 5~10 m,the preliminary conclusion was that coral reefs’ special topographic caused it.相关资源
