Logo detection for indoor positioning

摘要

Example methods, apparatuses, or articles of manufacture are disclosed herein that may be utilized, in whole or in part, to facilitate or support one or more operations or techniques for logo detection for indoor positioning for use in or with a mobile device. Briefly, in accordance with one implementation, a method may include extracting, at a mobile device, visual features from one or more images captured via a camera sensor of the mobile device; and estimating a location of the mobile device based, at least in part, on a match between extracted visual features and one or more brand-specific visual signatures associated with one or more points of interest of one or more known locations. In some instances, an estimated location of a mobile device may be refined based, at least in part, on at least one additional POI of one or more POIs of one or more known locations.

主权项

1. A mobile-based method for estimating a location of a mobile device, comprising:
receiving, at said mobile device, one or more brand-specific visual signatures associated with one or more points of interest (POIs) of one or more known locations; extracting visual features from one or more images captured via a camera sensor of said mobile device; matching said extracted visual features and said one or more received brand-specific visual signatures; and estimating a location of said mobile device based, at least in part, on:
a match between said extracted visual features and said one or more brand-specific visual signatures associated with said one or more POIs of one or more known locations, andan estimation of a pose of said mobile device while said one or more images are captured via said camera sensor; wherein said pose is estimated based, at least in part, on a line of sight angle of said mobile device relative to two or more POIs, and said line of sight angle comprises an angle formed between an optical axis extending axially from a camera lens of said mobile device to a logo observation line along which at least a portion of a logo is presented.
