| 摘 要： | 针对可见光图像在受到红外光串扰的情况下产生的偏色现象，提出了一种基于多项式回归构建解串扰矩阵的四带图像（RGB三带和IR近红外带）偏色校正算法，该算法在特定的光源条件下，利用标准色卡的24个色块，采用多项式回归的思想构建解串扰矩阵.使用该解串扰矩阵对同种光源条件下拍摄的四带图像进行偏色校正，达到去除红外光串扰的目的.实验结果表明，该方法只需进行一次标定校正矩阵，就可以对同种光源条件下拍摄的不同图像进行偏色校正，恢复图像自然的色彩.

| Abstract: | The images combining visible and infrared light would produce color deviation. In response to this phenomenon, this study proposes a de-crosstalk matrix color correction algorithm based on polynomial regression to counter the crosstalk problem of four-band images (RGB three-band and IR near-infrared band). Under specific lighting conditions, the algorithm uses 24 color blocks of standard color checker to build the de-crosstalk matrix according to the idea of polynomial regression. The de-crosstalk matrix will be used for four-band images which are taken under the same lighting conditions to remove the near-infrared crosstalk and realize color correction. The experimental results indicate that the method does not only need to calibrate the correction matrix at one time, the color deviation images taken under the same lighting conditions will be corrected and restored the natural colors of themselves thereafter. |
