Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0050] Such as figure 1 shown.

[0051] A method for indoor positioning based on indoor LED lights and smart phone cameras. The key is to use the smart phone camera as a terminal for receiving information to receive the identification information sent by LED lights. The technical principle is to convert the information that needs to be transmitted into a piece of code , Control the high-speed flickering of LED lights. Generally, human eyes are not sensitive to flickering above 60Hz. In order to ensure the quality of lighting, the general flickering speed will be greater than 200Hz and less than 2000Hz to ensure that the human eye will not feel uncomfortable. High-speed flickering can only be achieved with LED lighting because of its high response speed. When a tourist with a smart mobile terminal (smartphone, the same below) enters the lighting area o...

Abstract

A method for implementing indoor location based on indoor LED lamps and intelligent cellphone cameras is characterized by comprising the steps of first, arranging sufficient LED lamps indoors, configuring a fixed ID (identifier) for each LED lamp, setting, in a server, corresponding geological location coordinates for each ID, and enabling the LED lamps to transit ID-containing high-frequency identification information continuously; second, using cameras of intelligent mobile terminals to receive scenario reflected light containing the high-frequency identification information transmitted by the LED lamps, and decoding and recognizing image signals to obtain ID numbers of the LED lamps; third, allowing the intelligent mobile terminals to automatically transmit the decoded ID numbers to the server, and querying to obtain geological location coordinates of a location so as to provide basis for acquiring the location, displaying a map of periphery, and implementing navigation. The method has the advantages of high recognition speed, good location accuracy, and good anti-jamming property.

Description

technical field [0001] The invention relates to a positioning technology, in particular to an indoor positioning technology, in particular to a method for realizing indoor positioning by using indoor LED lights and a camera of a smart phone. Background technique [0002] When it comes to positioning and navigation, GPS is currently more mature, and China has also launched its own satellite positioning system, the Beidou Satellite Positioning System. However, satellite positioning can only be used in outdoor environments. Once indoors, satellite positioning cannot be used because the navigation signal attenuates too fast. However, in some larger indoor scenes, such as transportation hubs, subways, large shopping malls, supermarkets, parking lots, etc., there is a need to know your exact location, and indoor positioning technology emerges as the times require. This technology is of great significance in public services, mobile Internet applications, etc. It is an extension of...
