Abstract

The embodiment of the invention provides a pixel communication method, which comprises the following steps: acquiring information to be sent, encoding the information to be sent and packaging the information into at least one data frame; converting the data frame into a plurality of frame image information composed of pixel points, constructing video information through the frame image information, and sending the video information to a receiving end in the form of visible light; wherein the video information is transmitted through a luminous pixel point in a screen or a projected image as anoptical signal transmitting end, and the receiving end receives the video information through a camera. The method provided by the invention, in this way, a message to be transmitted is converted intovideo message and projected onto a screen, communication in the visible band can transmit a rich variety of information, not limited and affected by the Internet signal coverage environment, can alleviate the depletion of spectrum resources of mobile communications, and based on the highly directional characteristics of the short-wave spectrum of visible light, can be applied in the electromagnetic sensitive environment.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless optical communication, and in particular, to a pixel communication method, an information sending terminal, and an information receiving terminal. Background technique [0002] Due to the increasing use of mobile digital terminals, especially the increasing user demand for video services, wireless spectrum resources are becoming increasingly scarce, and the introduction of visible light communication is a huge expansion of the communication spectrum. Among them, visible light has a huge bandwidth of 380-780nm (equivalent to 405THz), which can alleviate the imminent depletion of wireless spectrum resources. Visible light communication technology refers to a communication method that uses light in the visible light band as an information carrier, does not use optical fiber and other wired channel transmission media, and uses air as a medium to transmit optical signals. At the...
