A LiDAR/Visual SLAM Backend with Loop Closure Detection and Graph Optimization
LiDAR (light detection and ranging), as an active sensor, is investigated in the simultaneous localization and mapping (SLAM) system. Typically, a LiDAR SLAM system consists of front-end odometry and back-end optimization modules.

Loop Closure Detection Using Local 3D Deep Descriptors [PDF]
We present a simple yet effective method to address loop closure detection in simultaneous localisation and mapping using local 3D deep descriptors (L3Ds). L3Ds are emerging compact representations of patches extracted from point clouds that are learnt from data using a deep learning algorithm.

SVG-Loop: Semantic–Visual–Geometric Information-Based Loop Closure Detection
Loop closure detection is an important component of visual simultaneous localization and mapping (SLAM). However, most existing loop closure detection methods are vulnerable to complex environments and use limited information from images. As higher-level
