iNavFIter-M: Matrix Formulation of Functional Iteration for Inertial Navigation Computation

no code implementations17 Nov 2022 Hongyan Jiang, Maoran Zhu, Yanyan Fu, Yuanxin Wu

This paper proposes a computationally efficient matrix formulation of the functional iteration approach, named the iNavFIter-M.

A Pose-only Solution to Visual Reconstruction and Navigation

no code implementations2 Mar 2021 Qi Cai, Lilian Zhang, Yuanxin Wu, Wenxian Yu, Dewen Hu

Visual navigation and three-dimensional (3D) scene reconstruction are essential for robotics to interact with the surrounding environment.

A Trident Quaternion Framework for Inertial-based Navigation Part I: Rigid Motion Representation and Computation

no code implementations24 Feb 2021 Wei Ouyang, Yuanxin Wu

This paper proposes a compact and elegant representation of the body's attitude, velocity and position, with the aid of a devised trident quaternion tool in which the position is accounted for by adding a second imaginary part to the dual quaternion.

A Trident Quaternion Framework for Inertial-based Navigation Part II: Error Models and Application to Initial Alignment

no code implementations24 Feb 2021 Wei Ouyang, Yuanxin Wu

This work deals with error models for trident quaternion framework proposed in the companion paper (Part I) and further uses them to investigate the odometer-aided static/in-motion inertial navigation attitude alignment for land vehicles.

Identifying feature correspondence between two images is a fundamental procedure in three-dimensional computer vision.

General Method for Prime-point Cyclic Convolution over the Real Field

no code implementations9 May 2019 Qi Cai, Tsung-Ching Lin, Yuanxin Wu, Wenxian Yu, Trieu-Kien Truong

A general and fast method is conceived for computing the cyclic convolution of n points, where n is a prime number.

StructVIO : Visual-inertial Odometry with Structural Regularity of Man-made Environments

no code implementations16 Oct 2018 Danping Zou, Yuanxin Wu, Ling Pei, Haibin Ling, Wenxian Yu

Instead of using Manhattan world assumption, we use Atlanta world model to describe such regularity.


Equivalent Constraints for Two-View Geometry: Pose Solution/Pure Rotation Identification and 3D Reconstruction

no code implementations13 Oct 2018 Qi Cai, Yuanxin Wu, Lilian Zhang, Peike Zhang

The PPO constraints are simplified and formulated in the form of inequalities to directly identify the right pose solution with no need of 3D reconstruction and the 3D reconstruction can be analytically achieved from the identified right pose.
