Continuous-Time Spatiotemporal Calibration of a Rolling Shutter Camera---IMU System

1 code implementation16 Aug 2021 Jianzhu Huai, Yuan Zhuang, Qicheng Yuan, Yukai Lin

To this end, we develop a calibration method for a RS-camera-IMU system with continuous-time B-splines by using a calibration target.

Segway DRIVE Benchmark: Place Recognition and SLAM Data Collected by A Fleet of Delivery Robots

no code implementations8 Jul 2019 Jianzhu Huai, Yusen Qin, Fumin Pang, Zichong Chen

Visual place recognition and simultaneous localization and mapping (SLAM) have recently begun to be used in real-world autonomous navigation tasks like food delivery.

Marginal Covariance of Parameters in New Observations

no code implementations9 May 2020 Jianzhu Huai

We have observed a common problem of solving for the marginal covariance of parameters introduced in new observations.

NOCT: Nonlinear Observability with Constraints and Time Offset

no code implementations16 Jul 2022 Jianzhu Huai, Yukai Lin, Yujia Zhang

To this end, we propose procedures to convert a system model of affine control inputs with linear constraints into a constraint-free standard model which is apt to be analyzed by the classic observability analysis procedure.

Geometric Wide-Angle Camera Calibration: A Review and Comparative Study

no code implementations15 Jun 2023 Jianzhu Huai, Yuan Zhuang, Yuxin Shao, Grzegorz Jozkow, Binliang Wang, Yijia He, Alper Yilmaz

These tests reveal the strengths and weaknesses of these camera models, as well as the repeatability of these GCC tools.

A Quick Guide for the Iterated Extended Kalman Filter on Manifolds

no code implementations18 Jul 2023 Jianzhu Huai, Xiang Gao

In contrast, the iterated EKF (IEKF) refines the state in the update step by iteratively solving a least squares problem.
