APPROACHES FOR MAPPING GEOGRAPHIC REGIONS

Abstract:

Systems, methods, and non-transitory computer-readable media can determine one or more sensor measurements captured by one or more sensors of a vehicle while navigating a geographic region. A sensor map representing the geographic region can be determined. The map can segment the geographic region into a grid of cells. A plurality of cells in the grid are associated with one or more corresponding sensor fingerprints. A threshold level of correlation can be determined between a captured sensor measurement and at least one sensor fingerprint associated with a cell in the grid. The vehicle can be localized within the geographic region based at least in part on the threshold level of correlation between the captured sensor measurement and the at least one sensor fingerprint of the cell.
