LiODOM - Adaptive Local Mapping for Robust LiDAR-Only Odometry

LiODOM is an open source C++ library for LiDAR-Only pose estimation and map building. It is based on minimizing a loss function derived from a set of weighted edge-to-line correspondences with a local map. The (unoptimized) global map is represented by a fast and efficient hash-based grid structure that speeds up searches and updates. The local map is obtained from the global map according to the current position of the vehicle.
