Abstract
A system to use submaps to control operation of a vehicle is disclosed. A storage system may be provided with a vehicle to store a collection of submaps that represent a geographic area where the vehicle may be driven. A programmatic interface may be provided to receive submaps and submap updates independently of other submaps.
Claims21
A method for performing localization for a vehicle in motion, the method being implemented by one or more processors and comprising:
- obtaining a set of sensor data captured by the vehicle at a given instance as the vehicle traverses a given area of a road network, the sensor data including passive image data;
- matching an image subset of the passive image data to a feature from a known feature set for the given area of the road network;
- and
- determining the location of the vehicle within the given area based on reference location information previously associated with the known feature set.
1 more element
A computer system comprising:
- a memory to store a set of instructions;
- one or more processors to use the set of instructions to:
- obtain a set of sensor data captured by the vehicle at a given instance as the vehicle traverses a given area of a road network, the sensor data including passive image data;
- match an image subset of the passive image data to a feature from a known feature set for the given area of the road network;
- and
- determineS the location of the vehicle within the given area based on reference location information previously associated with the known feature set.
