Using visible light-seeking authority, and the street lamp spread all over the world using in existing road administration is as the emission source of visible light signal, so that
On the premise of it need not increase extra cost, existing road administration facility is made full use of to realize visible light-seeking exactly；
Secondly as using street lamp as VISIBLE LIGHT EMISSION source to realize positioning, as long as being launched street lamp can be received
The position of light is that can complete positioning, due to generally not having intensive building near street lamp, so as to effectively keep away
Exempt from building and block influence to visible light-seeking；
Again, administration of highways center after marking on the electronic map to each street lamp position, and administration of highways center can be by
The electronic map of numbering is sent to mobile terminal, to obtain its week according to the electric signal after being handled through opto-electronic conversion by mobile terminal
The Position Number of street lamp is enclosed, and mobile terminal can be marked on the electronic map of its reception, so as to convenient shifting
Dynamic terminal user understands the accurate Position Approximate being presently in；
Finally, mobile terminal launches visible light signal strength conditions according to each street lamp, with visible light signal maximum intensity
Street lamp as the reference street lamp of mobile terminal, and be used as using reference street lamp position the second of the mobile terminal
Coordinate is put, the first position coordinate that then positions mobile terminal using gps signal and current gained second place coordinate
Average as the current particular location of mobile terminal, and by the current particular location of mobile terminal on its electronic map it is accurate
Be marked so that facilitate mobile terminal user knows the particular location being presently in exactly on the electronic map.
