On-manifold preintegration
Webregarding preintegration we come up with a novel first order development with respect to noise and bias based on Lie exponential coordinates that proves more accurate than the classical Taylor expansion of [17]. We derive additional “exact” preintegration formulas when IMU are either noise free, or bias free. 3 Web1 On-Manifold Preintegration Theory for Fast and Accurate Visual-Inertial Navigation Christian Forster, Luca Carlone, Frank Dellaert, Davide Scaramuzza Abstract—Current approach

Web3 de abr. de 2024 · Formula Student Driverless (FSD) requires students to design and build a driverless vehicle to race on track, which incurs great demands on the odometry solution. High accuracy odometry plays a significant role in Simultaneous Localization and Mapping (SLAM) and automatic navigation mission. This paper proposes an odometry method … WebIn addition, to avoid recalculating the reprojection matrices in de-skewing step, we use the intermediate variables in IMU preintegration to compensate for lidar motion distortion. The experimental results demonstrate that KFS-LIO can reduce half of the LOAM features and provide comparable accuracy with the state-of-the-art odometry.

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 Web13 de jun. de 2016 · $\Delta R_{ij},\Delta v_{ij},\Delta p_{ij}$即为preintegration measurements，即不考虑初值以及重力加速度项的相对测量。 注意到这些项包含有噪声$\eta$，我们也需要将它们分离出来。 在分离的过程中发现preintegration measurements是近似服从高斯分布的，即： $ \begin{aligned}\Delta\tilde{R}_{ij} & \approx\Delta …
