A comprehensive detection method of LED color is proposed based on phase space reconstruction and cluster analysis. According to the characteristic of HSL color model, chrominance information can be separated from the collected images. By using the method of phase space reconstruction, the chrominance matrix is converted into the chrominance information points in three-dimensional space. The noise pixels in the phase space reconstruction results are further eliminated through the cluster analysis to obtain the effective chrominance information of LED. The experimental results show that the proposed method can accurately detect the LED color information and the results are stable.
