  LiDAR sensors are becoming one of the most essential sensors in achieving
full autonomy for self driving cars. LiDARs are able to produce rich, dense and
precise spatial data, which can tremendously help in localizing and tracking a
moving vehicle. In this paper, we review the latest finding in 3D LiDAR
localization for autonomous driving cars, and analyse the results obtained by
each method, in an effort to guide the research community towards the path that
seems to be the most promising.
