Role of Deep Learning in Loop Closure Detection for Visual and Lidar SLAM: A Survey [PDF]
Loop closure detection is of vital importance in the process of simultaneous localization and mapping (SLAM), as it helps to reduce the cumulative error of the robot’s estimated pose and generate a consistent global map.

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.
