Embodiments of the invention disclose an adaptive multi-point tracking method and an adaptive multi-point tracking device based on visible-light communication, and relate to the technical field of optical communication. By using the device, terminal equipment is ensured to always obtain signals needed for stable data communication in the moving process, and the data communication effect of visible-light communication can be improved. The adaptive multi-point tracking method disclosed by the embodiment of the invention comprises the following steps: acquiring the number of terminal equipment and the position information of each piece of terminal equipment; calculating the moving trajectory of each piece of terminal equipment according to a preset moving scheme; determining the coverage area of a visible light source; and opening the visible light source and making the visible light source carry out tracking along the moving trajectory of the terminal equipment when there is one, and only one, piece of terminal equipment of which the moving trajectory falls in the coverage area of the visible light source.
