The embodiment of the invention provides an optical sensing device applied to a visible light communication system, the visible light communication system and an indoor positioning method, and the optical sensing device comprises a camera arranged on the optical sensing device; the optical sensing equipment is used for controlling the camera to shoot a visible light source fixed at the top of an indoor space to obtain a first image; and the optical sensing equipment is positioned in the indoor space by analyzing the first image shot by the camera. When the optical sensing equipment positions the optical sensing equipment in the indoor space by analyzing the first image shot by the camera, the optical sensing equipment is used for binarizing the first image to obtain a second image; a firstcoordinate of the visible light source is acquired from the second image; a second coordinate of the visible light source is determined according to the first coordinate; and the position of the optical sensing equipment in the indoor space is determined according to the second coordinates.
Description
technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an optical sensing device applied to a visible light communication system, a visible light communication system and an indoor positioning method. Background technique [0002] Visible light communication technology is a technology that uses high-speed bright and dark flashing signals invisible to the naked eye to transmit information using fluorescent lamps or light-emitting diodes. Visible light communication technology is often used in indoor positioning and data transmission. When performing indoor positioning, related technologies usually send the position information of light-emitting diodes through optical signals. algorithm for indoor positioning. However, since the optical signal not only carries the position information of the light emitting diode, but also carries other information, this information will have a certain impact on the positioning accura...
