摘　　要：提出了一种利用相空间重构、空间聚类分析方法综合完成LED颜色检测的方法.利用HSL颜色模型的特性,分离出采集到图像的色度信息;利用相空间重构方法,将二维的色度矩阵重构为三维空间内的色度信息点;利用空间聚类分析方法,进一步剔除相空间重构结果中的干扰像素点,得到有效的LED色度信息.实验结果证明,该方法能准确检测LED颜色信息,结果稳定.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.
