SYSTEM AND METHOD DETERMINING SPECTRUM USING FUZZY INFERENCE ALGORITHM EMPLOYING MEASUREMENT FROM LED SENSOR

摘要

PROBLEM TO BE SOLVED: To determine a spectrum based on a non-spectrum input using a reference database including a reflected spectrum and a training sample indicating an LED sensor output corresponding to the reflected spectrum. SOLUTION: The spectrophotometer of an LED base uses reconstructing algorithm based on a reference spectrophotometer and the spectrum information of light emitting source, and then converts the measurement of an integrated multiple light emitting body from a color sensor with a mounted non-full light emitting body to a fully mounted spectrum curve. A non-linear model such as a fuzzy inference system FIS is used to reconstruct the spectrum.
