MobileARLoc: On-device Robust Absolute Localisation for Pervasive Markerless Mobile AR
Changkun Liu, Yukun Zhao, Tristan Braud
Recent years have seen significant improvement in absolute camera pose estimation, paving the way for pervasive markerless Augmented Reality (AR). However, accurate absolute pose e…

HR-APR: APR-agnostic Framework with Uncertainty Estimation and Hierarchical Refinement for Camera Relocalisation
Changkun Liu, Shuai Chen, Yukun Zhao +3
Absolute Pose Regressors (APRs) directly estimate camera poses from monocular images, but their accuracy is unstable for different queries. Uncertainty-aware APRs provide uncertain…

Robust Localization with Visual-Inertial Odometry Constraints for Markerless Mobile AR
Changkun Liu, Yukun Zhao, Tristan Braud
Visual Inertial Odometry (VIO) is an essential component of modern Augmented Reality (AR) applications. However, VIO only tracks the relative pose of the device, leading to drift o…
