PLV-IEKF: Consistent Visual-Inertial Odometry using Points, Lines, and Vanishing Points
Tong Hua, Tao Li, Liang Pang +4
In this paper, we propose an Invariant Extended Kalman Filter (IEKF) based Visual-Inertial Odometry (VIO) using multiple features in man-made environments. Conventional EKF-based V…

TextSLAM: Visual SLAM with Semantic Planar Text Features
Boying Li, Danping Zou, Yuan Huang +3
We propose a novel visual SLAM method that integrates text objects tightly by treating them as semantic features via fully exploring their geometric and semantic prior. The text ob…
