Abstract

Research on high dynamic range (HDR) color management imposes critical requirements on calibration methods between imaging systems and standard radiation. This paper proposes a colorimetric calibration method based on digital chain measurement for imaging systems. First, a HDR colorimetric calibration process model for imaging systems is constructed based on an imaging chain. It includes a light source, target reflectance, optical system parameters, spectral sensitivities, and color matching functions. Subsequently, visual tristimulus values and three-channel response values of an imaging system are obtained using the proposed model in response to the same target, and the target characteristic parameters are adjusted to simulate different HDR imaging scenarios. Following that, various regression algorithms can be employed for HDR colorimetric calibration of imaging systems. The experimental findings demonstrate that the method proposed in this paper boasts a broader dynamic range and denser sampling, thereby enhancing the accuracy of colorimetric characterization models and achieving superior resolution in color measurement.

基于数字链的成像系统高动态范围比色标定方法。
高动态范围(HDR)色彩管理的研究对成像系统与标准辐射之间的校准方法提出了至关重要的要求。提出了一种基于数字链测量的成像系统比色校正方法。首先,构建了基于成像链的成像系统HDR比色校准过程模型;它包括光源、目标反射率、光学系统参数、光谱灵敏度和颜色匹配功能。随后,利用所提出的模型得到成像系统对同一目标的视觉三刺激值和三通道响应值,并调整目标特征参数以模拟不同的HDR成像场景。然后,各种回归算法可用于成像系统的HDR比色校准。实验结果表明,本文提出的方法具有更宽的动态范围和更密集的采样,从而提高了比色表征模型的准确性,并在颜色测量中获得了较好的分辨率。
