Image-Based Indoor Position Determination |
| 摘要 |
In one implementation, a method may comprise: determining a topological representation of an indoor portion of a building based, at least in part, on positions or number of lines in an image of the indoor portion of the building; and comparing the topological representation to one or more stored topological representations, for example in a digital map of the building, to determine a potential position of the indoor portion of the building. |

1. A method comprising:
extracting linear features from an image of an indoor portion of a building, said image captured by a camera at a mobile station; determining a topological representation of said indoor portion based, at least in part, on positions or quantity of said linear features in said image; and comparing said topological representation to stored topological representations of said building to determine a candidate position of said mobile station.
