| 中文摘要: |
| 介绍了利用数码成像器件测量不均匀面光源亮度的有效方法,分析了它与传统点式亮度计的差别.对影响数码成像亮度测量精度的成像定标、非线性校正、多重曝光等几种方法进行了模拟和讨论,为数码成像亮度仪的设计提供了理论依据. |
| 英文摘要: |
| This paper proposes a novel and practical method of measuring nonuniform light source by using digital imaging device.The differences between it and that by the conventional spot sighting luminance meter have been analyzed.The factors that influence the accuracy of digital imaging luminance measurement,such as imaging scaling,nonlinearity correction,multiple exposure,are numerically simulated and discussed.The results can be used for the design of digital imaging luminance meter. |
