Problems solved by technology

[0003] GPS positioning technology is based on satellite navigation to determine the geographical location. Outdoors, because the satellite signal is better, it can achieve more accurate outdoor positioning. However, it cannot be applied indoors where the satellite signal is poor. As a supplement to GPS positioning technology, the existing Technology exists based on WiFi (Wireless Fidelity) indoor positioning technology
[0004] The indoor positioning technology based on WiFi mainly realizes positioning through the wireless local area network composed of wireless access points. However, the WiFi signal is easily interfered by other signals, and the energy consumption brought by WiFi is also high

Abstract

The embodiment of the invention provides a positioning method, a terminal, LED (Light-Emitting Diode) control equipment and a system. The method comprises the following steps: receiving an optical signal transmitted by an LED light source, wherein the optical signal carries identification information relevant to a position at which the LED light source is positioned; resolving the optical signal, and determining the identification information; determining a geographic position relevant to the identification information according to preset geographic positions relevant to the identification information; and taking the determined geographic position as a positioning result. The positioning method provided by the embodiment of the invention is suitable for indoor positioning, has relatively high interference resistance, and is relatively low in power consumption.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a positioning method, a terminal, LED control equipment and a system. Background technique [0002] Positioning refers to a process of obtaining geographic location information (such as latitude and longitude coordinates) of a terminal. Currently, a commonly used positioning technology mainly includes a GPS (Global Positioning System, Global Positioning System) positioning technology. [0003] GPS positioning technology is based on satellite navigation to determine the geographical location. Outdoors, because the satellite signal is better, it can achieve more accurate outdoor positioning. However, it cannot be applied indoors where the satellite signal is poor. As a supplement to GPS positioning technology, the existing Technology exists based on WiFi (Wireless Fidelity) indoor positioning technology. [0004] The indoor positioning technology based on WiFi mainly reali...
