Digest for Localization or Fingerprinted Overlay
First Claim
1. A method for mapping an environment proximal to a vehicle, the method comprising:
- obtaining a current location of the vehicle according to a map of the environment;
detecting at least one characteristic of the environment at the current location; and
storing the at least one characteristic in a characteristic digest, the characteristic digest respectively associating one or more locations in the environment to one or more sets of previously detected characteristics in the environment; and
associating the at least one characteristic with the current location in the characteristic digest.

Abstract
A method for mapping an environment proximal to a vehicle includes obtaining a current location of the vehicle according to a map of the environment, detecting at least one characteristic of the environment at the current location, and storing the at least one characteristic in a characteristic digest. The characteristic digest respectively associates one or more locations in the environment to one or more sets of previously detected characteristics in the environment. The method also includes associating the at least one characteristic with the current location in the characteristic digest.
