DETERMINING LOCALIZATION FROM IMAGES OF A VICINITY

摘要

A method and system for determining a user's location in a pre-mapped environment from one or more images of the user's vicinity is provided. The method includes providing a probabilistic data structure derived from a second data structure, querying the second data structure for corresponding feature characteristics stored in the second data structure that respectively correspond to each feature characteristic from a plurality of feature characteristics, which may be a subset of an initial plurality of feature characteristics extracted from the one or more images from the user's vicinity, and identifying the user's location from the corresponding feature characteristics. The plurality of feature characteristics is determined by querying the probabilistic data structure.

1. A method for determining a user's location in a pre-mapped environment from one or more images of the user's vicinity, the method comprising:
providing a first data structure, wherein the first data structure is a probabilistic data structure derived from a second data structure; querying the second data structure for corresponding feature characteristics stored in the second data structure that respectively correspond to each feature characteristic from a plurality of feature characteristics,
wherein the plurality of feature characteristics is a subset of an initial plurality of feature characteristics extracted from the one or more images of the user's vicinity, andwherein the plurality of feature characteristics is determined by queries to the first data structure; and identifying the user's location in the pre-mapped environment from the corresponding feature characteristics.
