Abstract:
Combined with the Commission International de l’Eclairage (CIE) color system, the hue angle information acquisition method based on satellite multispectral remote sensing reflectance was used to obtain the hue angle information data set. Then the hue angle data set was matched with the survey dataset to establish a inversion model of total chlorophyll and suspended particulate matter concentration based on the hue angle information. Lastly, the high-definition digital image of the Dalian sea area was used for verification. The results show that the inversion model of chlorophyll
a concentration and suspended particulate matter concentration based on the hue angle information has high accuracy, and the correlation coefficients
R2 between the two parameters and the hue angle are 0.73 and 0.81, respectively, and both of them are negatively correlated with the hue angle. The proposed model can be integrated with drones, digital cameras and other systems, and combined with satellite remote sensing to create a three-dimensional monitoring system for providing a new method for marine water quality environmental monitoring.
