Ship false positioning identification method based on big data

The identification method of false ship positioning information proposed in this paper divides the voyage from the starting point to the destination into multiple sub-voyages, obtains the historical positioning information of each sub-voyage from the starting point to the destination, and averages the historical positioning information of each sub-voyage to obtain the averaged historical positioning information. By obtaining the positioning information of the ship to be identified for each sub-voyage from the starting point to the destination, a false positioning information identification model is set, and the position change curve of the ship to be identified is obtained based on the averaged historical positioning information and the positioning information of the ship to be identified. The monitoring point of the ship to be identified is obtained on the position change curve, and the curve change angle of all two adjacent monitoring points in the entire voyage is obtained. By setting the identification strategy of the positioning information of the ship to be identified, the positioning information of the ship to be identified is identified according to the identification strategy and combined with the curve change angle.
