| 摘 要： | 本文利用图像数字化处理系统对天空亮度分布进行了定量实测,提出了除下雨等天空特别阴暗的、一般需要人工照明的特殊天气现象外,根据天空亮度分布规律,将天空划分为CIE晴天空、似晴天空、似阴天空和CIE全阴天空,并由模糊数学证明这种天空分类是合理的。

| Abstract: | This paper presents the quantitative measurement to thesky luminance distribution with the help of the figure and numericalsystem of disposal,and suggests that the actual sky,with exception ofa few particular weather conditions,such as rain in which artificiallighting is needed,may be divided into CIE clear sky,pseudo-clearsky,pseudo-overcast sky and CIE overcast sky according to the skyluminance distribution,and verify the sky classification is reasonablewith fuzzy mathematics. |
