Continuous Preintegration Theory for Graph-based Visual-Inertial Navigation

In this paper we propose a new continuous preintegration theory for graph-based sensor fusion with an inertial measurement unit (IMU) and a camera (or other aiding sensors). Rather than using discrete sampling of the measurement dynamics as in current methods, we analytically derive the closed-form solutions to the preintegration equations, yielding improved accuracy in state estimation...
