METHOD AND A SERVER FOR UPDATING A MAP REPRESENTATION

Methods and server for updating a map representation of a geographical region is disclosed. For a given timestamp along a past trajectory of the SDC when the SDC has been located at a given location in the geographical region, the method includes: generating, using a localization algorithm, a set of...

Zusammenfassung:	Methods and server for updating a map representation of a geographical region is disclosed. For a given timestamp along a past trajectory of the SDC when the SDC has been located at a given location in the geographical region, the method includes: generating, using a localization algorithm, a set of candidate locations using a set of point clouds and the map representation, determining, using a convergence metric, a parameter for evaluating quality of localization of the localization algorithm when the SDC is located in the candidate portion of the map representation, identifying, using the parameter, the candidate portion of the map representation as an outdated portion of the map representation, and updating the outdated portion of the map representation using point cloud data captured by the LIDAR system.
