The invention provides a multi-fusion seaweed field
ecosystem observation method,
system, device and medium, and belongs to the technical field of
ecological monitoring, the method comprises the following steps: obtaining
chlorophyll a concentration, seaweed
canopy spectrum and three-dimensional
biomass point cloud; aligning the
chlorophyll a concentration of the target sea area with the seaweed
canopy spectrum, and fusing the three-dimensional
biomass point cloud to generate a three-dimensional
biomass model; constructing an in-situ sampling network to monitor
water quality parameters, benthic
organism video streams and eDNA metagenome
sequencing data, calibrating a three-dimensional biomass model, executing
anomaly detection through a lightweight LSTM model, and identifying benthic
organism species in real time through an improved YOLOv5 model; constructing a graph neural network, outputting a
carbon sink prediction value, generating a brown tide early warning
signal when the
carbon sink prediction value is lower than a dynamic threshold value, optimizing a patrol path of the unmanned aerial vehicle based on
reinforcement learning, and improving the sampling frequency of the
water quality sensor. According to the invention, multi-fusion monitoring of the seaweed field is realized, the ecological condition is accurately evaluated, and abnormity is warned in advance.
