Consistent and Optimal Solution to Camera Motion Estimation
Guangyang Zeng, Qingcheng Zeng, Xinghan Li +4
Given 2D point correspondences between an image pair, inferring the camera motion is a fundamental issue in the computer vision community. The existing works generally set out from…
SCORE: Saturated Consensus Relocalization in Semantic Line Maps
Haodong Jiang, Xiang Zheng, Yanglin Zhang +4
We present SCORE, a visual relocalization system that achieves unprecedented map compactness by adopting semantically labeled 3D line maps. SCORE requires only 0.01\%-0.1\% of the…
Distributed Invariant Kalman Filter for Object-level Multi-robot Pose SLAM
Haoying Li, Qingcheng Zeng, Haoran Li +2
Cooperative localization and target tracking are essential for multi-robot systems to implement high-level tasks. To this end, we propose a distributed invariant Kalman filter base…
Optimal camera-robot pose estimation in linear time from points and lines
Guangyang Zeng, Biqiang Mu, Qingcheng Zeng +4
Camera pose estimation is a fundamental problem in robotics. This paper focuses on two issues of interest: First, point and line features have complementary advantages, and it is o…
