A Geometric Framework for Absolute Pose and Velocity Estimation with Event Cameras

Zibin Liu, Shunkun Liang, Banglei Guan +3

Despite the rapid advancements in event-based motion estimation, current geometric methods primarily focus on velocity estimation. However, absolute pose estimation, which is equal…

Six-Point Method for Multi-Camera Systems with Reduced Solution Space

Banglei Guan, Ji Zhao, Laurent Kneip

Relative pose estimation using point correspondences (PC) is a widely used technique. A minimal configuration of six PCs is required for two views of generalized cameras. In this p…

Affine Correspondences between Multi-Camera Systems for Relative Pose Estimation

Banglei Guan, Ji Zhao

We present a novel method to compute the relative pose of multi-camera systems using two affine correspondences (ACs). Existing solutions to the multi-camera relative pose estimati…

On Relative Pose Recovery for Multi-Camera Systems

Ji Zhao, Banglei Guan

The point correspondence (PC) and affine correspondence (AC) are widely used for relative pose estimation. An AC consists of a PC across two views and an affine transformation betw…

Hybrid Rotation Averaging: A Fast and Robust Rotation Averaging Approach

Yu Chen, Ji Zhao, Laurent Kneip

We address rotation averaging (RA) and its application to real-world 3D reconstruction. Local optimisation based approaches are the de facto choice, though they only guarantee a lo…

Minimal Cases for Computing the Generalized Relative Pose using Affine Correspondences

Banglei Guan, Ji Zhao, Daniel Barath +1

We propose three novel solvers for estimating the relative pose of a multi-camera system from affine correspondences (ACs). A new constraint is derived interpreting the relationshi…

Minimal Solutions for Relative Pose with a Single Affine Correspondence

Banglei Guan, Ji Zhao, Zhang Li +2

In this paper we present four cases of minimal solutions for two-view relative pose estimation by exploiting the affine transformation between feature points and we demonstrate eff…

An Efficient Solution to Non-Minimal Case Essential Matrix Estimation

Ji Zhao

Finding relative pose between two calibrated images is a fundamental task in computer vision. Given five point correspondences, the classical five-point methods can be used to calc…

Density-Based Region Search with Arbitrary Shape for Object Localization

Ji Zhao, Deyu Meng, Jiayi Ma

Region search is widely used for object localization. Typically, the region search methods project the score of a classifier into an image plane, and then search the region with th…
