基于光谱相似性进行水深探测的研究

The study on water depth inversion based on spectral similarity

基于水深遥感反演方程与水面接收光谱随水深变化的特点,实验研究了水深光谱相似性与水深间的关系。结果表明,不同水深一阶微分光谱相似性与水深值近似满足指数变化规律。利用拟合公式进行误差分析,测量水深与实际值最大误差为16%,反演效果良好。

Based on inversion equation of the water-depth remote, and the relationship between received spectra of water surface and the water depth, the similarity of water depth spectrum was studied experimentally. The results show that the similarity of the first derivative spectra of different water depth approximately changes exponentially with depth value. Error analysis using the fitting formula indicates that the maximum error of measured water depth is 16%, which was good.
