In this paper,an improved spatio-temporal alignment measurement method is presented to address the inertial match-ing measurement of hull deformation under the coexistence of time delay and large misalignment angle.Large misalignment angle and time delay often occur simultaneously and bring great challenges to the accurate measurement of hull deformation in space and time.The proposed method utilizes coarse alignment with large misalignment angle and time delay estimation of iner-tial measurement unit modeling to establish a brand-new spatio-temporal aligned hull deformation measurement model.In addi-tion,two-step loop control is designed to ensure the accurate description of dynamic deformation angle and static deforma-tion angle by the time-space alignment method of hull deforma-tion.The experiments illustrate that the proposed method can effectively measure the hull deformation angle when time delay and large misalignment angle coexist.
