SYSTEM AND METHOD FOR COMMUNICATION OVER COLOR ENCODED LIGHT PATTERNS

摘要

The present invention includes a light communication method and system wherein messages are transmitted via color code flashes. The light communication may be transmitted using multiple elements restricted to a particular function, including calibration transmission and data transmission.

1. A light-based communication method for the color-coded transmission of a message, said method comprising the steps of:
initializing a light-emission transmitter, with a transmitter arithmetic logic unit (“ALU”) and a transmitter nontransitory computer-readable storage medium, for transmitting from a data transmission element a color stream transmission comprising data converted into original code color triplets selected from stock code color triplets within a predefined color gamut, and transmitting from a calibration transmission element a calibration array comprising at least one original calibration color triplet representative of volumetric extents of code color triplet channels, wherein said data transmission element and said calibration transmission element occupy spatially distinct positions; transmitting with said transmitter both said color stream transmission from said data transmission element and said calibration array from said calibration transmission element; receiving both said color stream transmission and said calibration array on a distinct receiver, with a receiver ALU and a receiver nontransitory computer-readable storage medium, positioned proximate to said transmitter with a sensor adapted to interpret color flashes as received color triplets, wherein said receiver has a priori environmental knowledge of said calibration array; calculating a correction calibration by discerning: a gamut calibration, derived from normalizing said calibration color triplets based on a multidimensional difference between said received color triplets and said original color triplets of said calibration array; approximating said original code color triplets by plotting received code color triplets, after application of said correction calibration, as multidimensional plot points to locate a nearest neighbor from a multidimensional plot of stock code color triplet points representative of a binary string; and extracting said data from said color stream transmission by translating said binary string to a translated data bit sequence.
