Abstract

The invention relates to the technical field of visible light communication, in particular to a visible light communication based navigation method and device, a computer readable medium and a wireless communication terminal. The method comprises the following steps of receiving an optical signal from a present sending terminal, and demodulating the optical signal to obtain position information and state parameter information of the present sending terminal; displaying navigation information according to the position information of the present sending terminal, and evaluating the present sending terminal according to state parameter information to obtain an evaluation result; and when the evaluation result is a first preset evaluation result, generating a first navigation switching instruction, so that terminal equipment calls a GPS assembly according to the navigation switching instruction and switches to a GPS navigation mode for auxiliary navigation. According to the scheme, when the terminal equipment cannot carry out accurate navigation in the visible light navigation mode, the GPS assembly can be switched for navigation, and the navigation stability and accuracy of the terminal equipment are ensured.

Description

technical field [0001] The present disclosure relates to the technical field of visible light communication, and in particular to a navigation method based on visible light communication, a navigation device based on visible light communication, a computer-readable medium, and a wireless communication terminal. Background technique [0002] Visible light communication (Visible Light Communication, VLC) technology is to transmit information by using high-speed bright and dark flashing signals invisible to the naked eye emitted by fluorescent lamps or light-emitting diodes. Connect the high-speed Internet wire device to the lighting device, insert the power plug be usable. The system made by using this technology can cover the range reached by indoor lighting, and the computer does not need to be connected by wires, so it has broad development prospects. [0003] At present, visible communication technology is mainly used in indoor navigation, outdoor navigation and data tran...
