Claims23
A method of indoor navigation using a mobile device, which method comprising:
- determining an indoor specified area in which the mobile device is located using a received indoor wireless transmission;
- downloading a light sources map of indoor real light sources of said indoor specified area based on and in response to said determining an indoor specified area in which the mobile device is located using a received indoor wireless transmission;
- detecting a one or more indoor real light sources in said indoor specified area using an optical sensor of said mobile device;
- measuring a rotation orientation of said mobile device using an orientation sensor, to determine a rotation orientation of said mobile device when said detecting said one or more indoor real light sources;
- determining a spatial relationship between said one or more detected indoor real light sources and said mobile device, based on signals received by said optical sensor and said measured rotation orientation of said mobile device;
- accurately determining a position of said mobile device within said determined indoor specified area using said downloaded indoor real light sources map, said signals received by said optical sensor and said spatial relationship that was determined based on said measured rotation orientation.
