Abstract
Provided is an apparatus and method associated with a location based service, and an apparatus for integrated positioning that may sense positioning-associated information that is in proximity to a user. The apparatus may hierarchically classify the sensed positioning-associated information into multiple categories of accuracy based on a predetermined criterion, and estimate the location of the user in order of low accuracy information to more precise accuracy information.
Claims17
An apparatus, the apparatus comprising:
- a memory configured to store computer-readable instructions;
- and
- a processor configured to execute the computer-readable instructions to acquire an initial location estimate of the apparatus based on first positioning information according to a first coverage area,
- acquire second positioning information within the first coverage area based on the initial location estimate, and
- estimate a present location of the within the second coverage area based on the second positioning information,
- wherein the first coverage area is broader than the second coverage area, and the first positioning information is acquired by a first sensing technology and the second positioning information is acquired by a second sensing technology.
A method of estimating a location of an apparatus, the method comprising:
- acquiring an initial location estimate of the apparatus based on first positioning information according to a first coverage area;
- acquiring second positioning information according to a second coverage area within the first coverage area based on the initial location estimate;
- and
- estimating a present location of the apparatus within the second coverage area based on the second positioning information,
- wherein the first coverage area is broader than the second coverage area, and
- wherein the first positioning information is acquired by a first sensing technology and the second positioning information is acquired by a second sensing technology.
A non-transitory computer-readable medium instructions that, when executed by a processor cause the processor to:
- acquire an initial location estimate of the apparatus based on first positioning information according to a first coverage area;
- acquire second positioning information according to a second coverage area within the first coverage area based on the initial location estimate;
- and
- estimate a present location of the apparatus within the second coverage area based on the second positioning information,
- wherein the first coverage area is broader than the second coverage area, and
- wherein the first positioning information is acquired by a first sensing technology and the second positioning information is acquired by a second sensing technology.
