RA-L 2022

Distribution-to-distribution-based lidar odometry is known for its good accuracy, while it cannot run in real-time when the number of points is large. To alleviate this problem, Faster Generalized Iterative Closest Point (FasterGICP) is proposed in this letter, in which an acceptance-rejection sampl

Regression Forest Based RGB-D Visual Relocalization Using Coarse-to-Fine Strategy

Ji-kai Wang, Peng Wang, Deyun Dai, Meng Xu, Zonghai Chen

RA-L 2020

Visual relocalization plays an important role in computer vision and robotics. However, feature ambiguities have made it remain challenging. In this work, we propose a novel regression forest based visual relocalization method that is performed in a coarse-to-fine manner. A topological regression tr
