地物偏振反射数据的获取与数据库的建立

典型地物偏振反射数据库系统是一个建于微机上的系统，该系统利用地物偏振反射测量装置与微机接口自动采集数据，目前，已建立单叶植被、土壤、岩矿、水体４个类型的偏振反射数据库，共采集数据４０多万个，不仅实现了偏振光数据与参数的快速查询，而且可以将调用查到有关数据进行屏幕上的实时绘图和多种分析，该系统的建立可为偏振光遥感技术的研究和应用提供信息服务，同时也为遥感信息的目标获取提供了一个新的手段。

Data capturing of surface object polarization reflection and establishing of polarization databases system

The system of typical surface feature polarization reflection databases was set up in a computer in order to give service to the study of polarization remote sensing information. Making use of the surface feature polarization reflection meter connected with the computer, the system can automatically collect data. At present, in the system, it has already established four types of polarization reflection data- bases including single leaf vegetation, soil, rockmine and water body databases. Meanwhile, it has already collected 400 000 data. The system can not only realize the inquiry of polarized light data and parameters, but also use the data that have been inquired to implement real-time drawing on the screen and various analyses. Establishing the system can provide information for the study and application of polarization remote sensing technology. Moreover it also provided a new means to acquire remote sensing information.
