Positioning system, positioning method, and program thereof
First Claim
1. A positioning system for detecting the position of a terminal, comprising:
- an illumination device configured to transmit unique information from a given installation position;
a terminal configured to receive the unique information transmitted from the illumination device; and
position estimation means configured to estimate the position of the terminal based on illumination installation position information and the unique information received by the terminal, said installation position information including the unique information and position information indicating the installation position of the illumination device in association with each other, wherein the position estimation means is configured to;
read out from the illumination installation position information the position information corresponding to the unique information based on one or more unique information received by the terminal within a past predetermined time period; and
estimate the position of the terminal based on the read out position information.

Abstract
A positioning system includes an illumination device, a terminal, and a positioning server. The illumination device transmits identification information. The terminal transmits the identification information received from the illumination device, to the positioning server. The positioning server uses the identification information received from the terminal, thereby searching an illumination installation position database registered in advance so as to identify the terminal position. This eliminates power supply for positioning infrastructure and facilitates attachment to a ceiling, thereby realizing the positioning infrastructure at a low cost.
