Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039] Such as Figure 1-5 As shown, the present invention discloses a multi-receiving point geometric center positioning method for visible light communication. For an indoor visible light communication system, several LED lights and a terminal carrying several receiving devices are arranged to locate the terminal target. A multi-receiving point geometric center positioning system and method in an indoor visible light communication system, comprising the following steps:

[0040] 1) Arrange several LED lamps with the same signal transmission power on the indoor ceiling as the optical signal transmitting end; configure several light receiving devices on the terminal that needs to be positioned as the signal receiving end, and the several light receiving devices are based on the geometry of the terminal. The center point is arranged as a regular polygon on the terminal...

Abstract

It discloses a precise locating method of utilizing indoor visible light communication system, which belongs to the field of visible light communication; arranging any number of light emitting diode (LED) lamps indoors, setting the signal transmission power of each LED lamp to be the same and fixing the absolute location of each LED lamp, the terminal required for locating is equipped with several receiving devices, whose relative positions are known, then a position coordinate of the terminal can be obtained by determining the geometric center position of this set of receiving devices through calculating the measured light signal power of the receiving devices on the terminal.

Description

technical field [0001] The invention relates to a multi-receiving point geometric center positioning method for visible light communication, which belongs to the field of visible light communication. Background technique [0002] With the development of outdoor positioning, indoor positioning has recently received extensive attention and has become an increasingly hot research field. Indoor positioning mainly refers to positioning people or objects indoors and providing some positioning-based services, such as private services, automated robot control, mobile commerce, tracking services, and navigation assistance. So far, many positioning-based researches have been proposed, and some technologies and products have been used for indoor positioning, such as radio frequency signal, wireless local area network (Wifi), infrared, laser (laser), ultrasonic (ultrasound) and so on. Generally speaking, radio frequency signals are the main way of indoor positioning today, but the accu...
