Indoor Positioning Terminal, Network, System and Method
First Claim
1. An indoor positioning terminal, comprising:
- a memory;
a camera; and
a processor, wherein the memory, the camera and the processor are coupled to each other,wherein the camera is configured to capture, with low exposure, a picture of an indoor lighting device,wherein the memory is configured to store indoor positioning map data, wherein the indoor positioning map data comprises an indoor electronic map and three-dimensional data information of the indoor lighting device that use a same frame of reference, andwherein the processor is configured to;
perform correlation matching between the three-dimensional data information of the indoor lighting device and the captured picture of the indoor lighting device; and
position a location of the indoor positioning terminal on the indoor electronic map when the picture is acquired.
