摘　　要：提出一种图像的色彩标定与补偿的方法,主要通过计算模型函数来判定不同颜色图像上的正确颜色定位。不同于常规的色彩定位途径,该方法并不需要空间上统一的色彩板,不需知道图像上的具体形状和大量的曝光图像集。此方法可应对非线性、非参数失真及因不同相机本身的色彩动态范围不一而带来的色彩失真。实验与结果分析表明,该方法能够有效地对光强的变化给予补偿,对图片的色彩起到均衡与标定的作用。In this paper we present a colour calibration and compensation method for digital image, it mainly uses model function computation to judge the correct colour positioning for different colour images. Unlike conventional eolour positioning ways, this method does not require a spatial uniform colour plates, and does not need to know the specific shape of the object in image and the large quantity of exposed image set. It can deal with the nonlinear and non-parametric distortions, as well as the colour distortion caused by different colour dynamic ranges of the cameras. Experiment and results analyses show that this method can effectively compensate for the variation of light intensity, and play a role of balance and calibration on colours of tl^e image.
