SYSTEM AND METHOD FOR PROVIDING INDOOR NAVIGATION SERVICES

摘要

Aspects of a system and method for providing indoor navigation services are described herein. Aspects of the disclosure provide an efficient method for identifying a location of a client device using accelerometers, gyroscopes, cameras, and/or position markers. Elements of the system relate to the determination of particular user locations by receiving location information pertaining to position markers from a remote server. A client device may identify a position marker using a camera, a Radio Frequency Identification (RFID) chip, or other method. An identifier describing the position marker may be sent to a remote server, and the remote server may provide a precise location to the client device.

主权项

1. A computer-implemented method for providing indoor navigation services, the method comprising:
estimating, using one or more processors, a position of a client device using a summation of detected movement of the client device; identifying a fixed position marker using the client device, wherein the fixed position marker comprises a marker identifier that uniquely identifies the position marker from a plurality of position markers; receiving at the one or more processors a set of marker information associated with the marker identifier, wherein the set of fixed marker information comprises a marker location of the position marker and environmental constraints for an area around the position marker; and updating, using the one or more processors, the estimated position of the client device using the marker location and the environmental constraints.
