Fishing boat trajectory data interpolation method and device based on multi-source heterogeneity

The invention discloses a fishing boat trajectory data interpolation method and device based on multi-source heterogeneity. The method comprises the following steps: acquiring multi-source heterogeneous fishing boat trajectory data; sequentially carrying out time interval standardization analysis, missing marking and normalization processing on the multi-source heterogeneous fishing boat trajectory data with different return frequencies; carrying out missing value interpolation on the preprocessed multi-source heterogeneous fishing boat trajectory data by utilizing the improved GANs; and integrating data after missing value interpolation processing of all fishing boat sensors on the same fishing boat. According to the method, the interpolation precision of the trajectory data of the missing fishing boats in the offshore area in the smart ocean scene can be improved by combining the multi-source heterogeneous fishing boat trajectory data, the fishing boat trajectory quality is optimized, the trajectory interpo
