Abstract
Geo-localization is the process by which an entity, such as an autonomous vehicle, can determine its precise location. In an example, a vehicle may include sensors, such as 4D radar sensors, that can capture a point cloud representing an environment within which the vehicle is positioned. An efficient representation of the point cloud is generated, which may be preceded by filtering the point cloud by removing points associated with transient elements. The efficient representation may be based on applying dimensionality reduction techniques to the point cloud or the filtered point cloud. The efficient representation may be compared with previously-generated representations which include geo-location, and were generated by the same dimensionality reduction techniques. Based on determining a match, the geo-location associated with the matched previously-generated representation may be assigned as a current geo-location of the vehicle.
