基于高光谱数据的赤潮检测方法

在讨论海水高光谱数据波形波峰和波谷产生机理的基础上,通过对高光谱数据波形结构形态的分析,提出了一组描述吸收峰和反射峰的特征参数,并且设计了一种计算这组特征参数的算法,然后基于其中的中心波长、强度和对应中心波长的值提出了3种赤潮识别的方法。试验证明这种方法可以成功地提取出吸收峰和反射峰的特征参数,3种赤潮识别方法可以进行赤潮的识别与预测。

Methods for detecting red tides based on hyperspectral data

Based on the discussion on the formative mechanism of wave crest and wave trough of seawater hyperspectral data,this paper presents a set of characteristic parameters by analyzing wave structure and configuration of the hyperspectral data. An algorithm,used for calculating the parameters,is devised,and then three red tide recognition methods are put forward based on three of the parameters including the center wavelength,the intensity and the value corresponding to the center wavelength.Experiments prove that the algorithm can successfully compute the parameters of the absorb apex and the echo apex,and the three red tide recognition methods can recognize and forecast red tides.
