Robust Initialization of VINS

T. Qin and S. Shen, “Robust initialization of monocular visual-inertial estimation on aerial robots,” in 2017 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), Vancouver, BC: IEEE, Sep. 2017, pp. 4225–4232. doi: 10.1109/IROS.2017.8206284.

这篇文章提出了一种鲁棒的视觉惯性系统初始化方法,通过松耦合的方式对齐 IMU 与视觉数据,主要解决了外参数标定、陀螺仪偏置估计、速度重力尺度和视觉惯性对齐等关键问题。

A Continuous-time VINS

S. Lovegrove, A. Patron-Perez, and G. Sibley, “Spline Fusion: A continuous-time representation for visual-inertial fusion with application to rolling shutter cameras,” in Procedings of the British Machine Vision Conference 2013, Bristol: British Machine Vision Association, 2013, p. 93.1-93.11. doi: 10.5244/C.27.93.

这篇论文主要工作是建立了卷帘相机的连续时域下的数学模型,初始化方法是利用 IMU 主动对齐视觉。

Handling Gauge Freedom in VINS

Z. Zhang, G. Gallego, and D. Scaramuzza, "On the Comparison of Gauge Freedom Handling in Optimization-Based Visual-Inertial State Estimation," IEEE Robot. Autom. Lett., vol. 3, no. 3, pp. 2710–2717, Jul. 2018, doi: 10.1109/LRA.2018.2833152.

这篇论文主要讨论了视觉惯性系统中规范自由度(Gauge Freedom)的处理方法,并对比了不同策略的效果。
