摘要： This application provides an information transmission method and a communication apparatus. In the technical solution of this application, a transmit end determines that a to-be-sent data packet includes a first information sequence and a second information sequence, the first information sequence includes source information, the second information sequence includes partial source information of the source information, and the second information sequence is used to perform luminance control on a light source. The partial source information is used for luminance control. This can ensure to implement luminance adjustability of the VLC system. A transmit end additionally transmits the partial source information to a receive end, so that the receive end can obtain more information for restoring the original source information. This is conducive to decoding of the data packet, thereby improving communication reliability of the VLC system.

摘要： Embodiments of the present invention disclose a positioning system and a positioning method. The positioning system includes at least one projection device, at least one camera, and a positioning engine. In a positioning process, the projection device projects a first optical pattern onto a target region, where the first optical pattern is used to mark a second picture; and the positioning engine may determine a location of a to-be-positioned object in the first optical pattern by using the second picture collected by the camera, so that the positioning engine can position the to-be-positioned object in the target region based on the location of the to-be-positioned object in the first optical pattern. It can be learned that huge manpower input is not required in the positioning process, thereby saving a lot of manpower costs.
