S${2}$ Loop: A Lightweight Spectral-Spatio Loop Closure Detector for Resource-Constrained Platforms
RA-L 2023
Visual loop closure detection is an essential backend task for long-term vSLAM applications. However, prior works cannot simultaneously meet the requirements of high recall and low computing and memory overhead, which prohibits their applicability to resource-constrained platforms. In this work we p
