Abstract

The invention discloses a mobile phone Android camera positioning system based on LED visible light communication and a positioning method thereof. The positioning system includes an LED visible light communication module, a signal receiving module, and a mobile phone positioning software module. The LED visible light communication module includes LED lamps. The mobile phone visible light communication signal receiving module includes a developed visible light communication camera. The visible light communication camera includes single camera heads on a mobile phone, and a camera system. The mobile phone positioning software module includes mobile phone client APP software which runs under an Android system and contains a positioning algorithm. An indoor positioning APP is loaded from a mobile phone client, and then, images can be taken using the camera system directly. Corresponding modulation information of each LED lamp is acquired by scanning the flick of the LED lamp, and the location of each lamp is determined through decoding. The exact location of the mobile phone client is calculated through the positioning algorithm, and the result is displayed on the mobile phone APP. Therefore, indoor positioning is realized.

Description

technical field [0001] The invention belongs to the technical field of positioning systems, and in particular relates to a mobile phone Android camera positioning system based on LED visible light communication and a positioning method thereof. Background technique [0002] In recent years, semiconductor LED lighting technology known as "green lighting" has developed rapidly. Compared with traditional lighting sources, white LEDs not only have low power consumption, long service life, small size, green environmental protection, but also have good modulation performance and response sensitivity. Advanced advantages. Utilizing this characteristic of LED, it can be used as lighting, and at the same time, it can modulate the signal onto the visible beam of LED for data transmission, and send information from the lamp to the client, realizing an emerging optical wireless communication technology, that is, visible light communication technology. Since visible light is closely re...
