APPROACHES FOR MAPPING GEOGRAPHIC REGIONS

Abstract:

Systems, methods, and non-transitory computer-readable media can determine sensor data collected by a fleet of vehicles while navigating a geographic region, the sensor data including sensor readings generated at least in part by a surface interaction between one or more tires of each of the fleet of vehicles and a road surface of the geographic region. A sensor map representing the geographic region can be determined. The map can segment the geographic region into a grid of cells. Instances of the collected sensor data can be associated with cells in the grid of cells. A corresponding fingerprint can be determined for one or more cells in the grid of cells based at least in part on a plurality of instances of sensor data associated with the cell.
