Abstract
Music-based positioning (MP) provides positioning service only sporadically and therefore is not suitable for indoor positioning. The present invention discloses system and method for music-based positioning aided by dead reckoning (MP-DR). At each signature burst (i.e. a highly unique short musical segment suitable for positioning), musical sounds are used for positioning. Between signature bursts, positioning is performed by dead reckoning (DR). MP-DR is an ideal combination of MP and DR: DR extends temporal coverage for MP, while MP provides the much needed periodic calibrations for DR.
Claims20
A mobile device, comprising:
- an acoustic positioning (AP) module for positioning said mobile device using a signature burst, wherein said signature burst includes human consumable sounds suitable for positioning;
- a dead-reckoning (DR) module for localizing said mobile device during an interval without signature burst.
A mobile device, comprising:
- a memory for storing a signature-burst meta-data associated with an audio content, wherein signature bursts include human consumable sounds suitable for positioning;
- an acoustic positioning module for positioning said mobile device using a signature burst of said audio content.
