Abstract

The embodiment of the present application discloses a visible light communication method, device and storage medium, which are applied to a visible light emission device, and the emission device includes a first lens module; the method includes: encoding the original data stream to be transmitted to obtain a transmission data packet, and converting the transmitted data packet into at least one frame of image; obtaining control information of at least one frame of image; wherein, the control information is used to instruct the receiving device to receive at least one frame of image; converting at least one frame of image and the control information into a visible light signal; based on The preset emission strategy controls the visible light signal to pass through the first lens module and emit parallel light into the target space. In this way, through the first lens module set in the transmitting device, the visible light is emitted parallel to the target space, and the multiple camera modules on the receiving device do not need to cooperate to focus when receiving the visible light signal of the target space, which simplifies the focusing process of the receiving device .

Description

technical field [0001] The present application relates to communication technology, and in particular to a visible light communication method, device and storage medium. Background technique [0002] As the radio frequency spectrum becomes increasingly tight, visible light communication (Visible Light Communication, VLC) becomes an important supplement. Visible light communication uses visible light to carry information, which is transmitted through space, and is received by an optical sensor to calculate the original information and complete the communication. [0003] Depending on the type of light sensor, VLC can be divided into several subfields. Among them, a system using a charge coupled device (Charge Coupled Device, CCD) / complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS) image sensor is called an optical camera communication system (Optical Camera Communication, OCC). Optical camera communication systems mostly use liquid crysta...
