Music-Based Positioning Aided By Dead Reckoning

摘要

Music-based positioning (MP) provides positioning service only sporadically. To continuously provide positioning service, the present invention discloses music-based positioning aided by dead reckoning (MP-DR). At each signature burst (i.e., a highly unique short musical segment suitable for positioning), sounds of a music piece or a human speech are used for positioning. Between signature bursts, dead reckoning (DR) is used.

主权项

1. An apparatus for continuously determining a geographic area thereof using sounds of a music piece comprising first and second signature bursts separated by a non-signature interval, comprising:
acoustic-positioning (AP) module for determining a position of said apparatus at said first and second signature bursts; a dead-reckoning (DR) module for determining a location of said apparatus by using said position as an initial location for dead reckoning during said non-signature interval.
