SemLoc: Accurate and Robust Visual Localization with Semantic and Structural Constraints from Prior Maps

ICRA 2022poster

Semantic information and geometrical structures of a prior map can be leveraged in visual localization to bound drift errors and improve accuracy. In this paper, we propose SemLoc, a pure visual localization system, for accurate localization in a prior semantic map. To tightly couple semantic and st…

Accurate and Robust Scale Recovery for Monocular Visual Odometry Based on Plane Geometry

ICRA 2021poster

Scale ambiguity is a fundamental problem in monocular visual odometry. Typical solutions include loop closure detection and environment information mining. For applications like self-driving cars, loop closure is not always available, hence mining prior knowledge from the environment becomes a more…
