摘要
A light receiver records images of light beams originating from a neighborhood of lights, and demodulates identifiers (IDs) from them at determined image positions. The receiver retrieves a set of neighbor IDs for each demodulated ID and a real-world position of the corresponding light. The receiver cross-references the demodulated IDs against the retrieved sets of neighbor IDs to reveal errors in the demodulated IDs. The receiver corrects the errors to produce correct IDs each indexing a real-world position that is correctly matched to one of the determined light beam positions. The receiver determines a position of the receiver relative to the light transmitter based on the correctly matched real-world and determined light beam positions.
