RGB-based Category-level Object Pose Estimation via Decoupled Metric Scale Recovery
Jiaxin Wei, Xibin Song, Weizhe Liu +3
While showing promising results, recent RGB-D camera-based category-level object pose estimation methods have restricted applications due to the heavy reliance on depth sensors. RG…
AEPP: A Less-constrained EPP Solver for Pose Estimation with Anisotropic Scaling
Jiaxin Wei, Stefan Leutenegger, Laurent Kneip
Perspective--Point (PP) stands as a fundamental algorithm for pose estimation in various applications. In this paper, we present a new approach to the PP problem with rela…
Cross-modal Place Recognition in Image Databases using Event-based Sensors
Xiang Ji, Jiaxin Wei, Yifu Wang +2
Visual place recognition is an important problem towards global localization in many robotics tasks. One of the biggest challenges is that it may suffer from illumination or appear…
Incremental Semantic Localization using Hierarchical Clustering of Object Association Sets
Lan Hu, Zhongwei Luo, Runze Yuan +3
We present a novel approach for relocalization or place recognition, a fundamental problem to be solved in many robotics, automation, and AR applications. Rather than relying on of…
Accurate Instance-Level CAD Model Retrieval in a Large-Scale Database
Jiaxin Wei, Lan Hu, Chenyu Wang +1
We present a new solution to the fine-grained retrieval of clean CAD models from a large-scale database in order to recover detailed object shape geometries for RGBD scans. Unlike…
