Exact preintegration formulas that account for rotating Earth, that is, centrifugal force and Coriolis force, are derived as a byproduct, and the factors are shown to be more accurate.

WebThe preintegration theory is introduced by Lupton [1] and is lifted to the manifold SO(3) by Forster et al. [2]. However, they assume that the linear acceleration is constant in the world frame which is problematic if the agent is moving fast. The accurate IMU preintegration model is proposed by Henawy et al. [3] where the linear WebTherefore, this article refines the process on the manifold model and utilizes the equivalent rotation vector to accumulate IMU measurements.
