摘　　要：为了研究GOG模型是否适用于平板电脑的特征化,对ipad、ipad pro、Huawei matepad和Huawei matepad pro进行了呈色性能测试,然后用GOG模型对4个平板电脑进行特征化,并使用多项式模型对预测结果进行修正,测试了模型对纯色色块以及纯色纺织品图像三刺激值的预测精度。结果表明:不同的平板电脑的呈色性能存在差异,对于通道独立性与色品恒定性较好的平板电脑,用GOG模型进行特征化可以获得较高的预测精度;对于通道独立性与色品恒定性较差的平板电脑,用GOG模型进行特征化获得的预测精度较低,即使经过多项式模型对预测结果进行修正,其预测精度也不够理想。该结果为平板电脑的特征化模型的选择提供了参考。In order to study whether the GOG model was suitable for the characterization of tablets, the chromogenic properties of ipad, ipad pro, Huawei matepad and Huawei matepad pro were tested. Then, the GOG model was used to characterize four tablets, and a polynomial model was used to modify the prediction results. The prediction accuracy of the model for the tristimulus values of pure colors and pure color textile images was tested. The results implied that different tablets had different chromogenic properties. For tablets with better channel independence and chroma consistency, the GOG model can obtain higher prediction accuracy. For tablets with poor channel independence and chroma constancy, the prediction accuracy obtained by GOG model was low. Even if the prediction results were modified by the polynomial model, the prediction accuracy was not ideal. These results provide a reference for the selection of characteristic model of tablets.
