| 摘 要： | 本文从图像处理的角度,基于统计方法对地基全天空类型识别进行了研究。通过对2007年1月的397组观测数据进行统计分析,确定了5种天空类型识别的判别阈值,实现了地基全天空类型的有效识别。结果表明,样本试验的分类结果为81.36％,普适性检验的结果为79.51％。

| Abstract: | The recognition of ground-based whole-sky condition types has been studied by the statistical method from the viewpoint of digital image processing.Based on the statistical analysis of the data during January 2007,this paper gives the thresholds of five sky condition types separately,and then the statistical method of the recognition of whole-sky condition types has been established.The results of the experimentation show that the average index of agreement is about 81.36% for the sample cloud maps and 79.8... |
