摘　　要：传统的光学能见度仪分别存在各自的观测缺陷.数字摄像能见度观测系统是采用先进的数字摄像技术,完全仿照人眼观测能见度的原理,根据能见度的定义研制的新型能见度自动观测仪.本文重点介绍了它的基本原理、系统组成、硬件结构以及软件流程.最后给出了数字能见度仪与传统光学能见度仪及人工观测的比对结果.结果显示三者具有相同的变化趋势,但存在一定的观测差异.在降雨等复杂天气条件下,会有较大差异.
The traditional optical visibility instruments bear their respectine in observation defects. Digital photography visiometer system（ DPVS） is one new type of visibility automation observation instrument,has been developed by adophing advanced digital photography technologe and imitating manual Visibi Lity observation by human ege based on the definition of visibi Lity visibility＇s theory and according to the definition of meteorological visibility. This thesis introduced the work theory of system、compose of system、structure of hardware and software flow,in the end some contrasted experiment results between DPVS and traditional optical visibility as well as manual visibility observation were given. The results show that the three ways share the same change trend with kind of differences. And in complicated weather conditions,like rainful the differences are more obvious.
