Aiming at the three-dimensional deformation problem of the ship during navigation, this paper proposes a hull deformation measurement method. Based on the hull deformation model, the extended Kalman filter algorithm is used to measure and predict the deformation angle of the measurement points on the ship’s hull by using the angular velocity obtained by the laser gyro measurement system as the input of the filter. In this paper, a certain type of ship is taken as the research object, and the proposed method is applied to the three-dimensional deformation measurement research of the ship.The experiment results show that the proposed method is feasible and practical for the measurement of hull deformation.
