利用偏振信息进行作物营养水平检测的初步研究

Primary Research of Crops Nutrition Detective Based on Polarization Information

利用Duncan MS3100 3CCD多光谱成像系统配肯高圆偏振镜片构成偏振信息采集系统,以大棚黄瓜叶为对象,初步研究反射光偏振信息中的偏振度与入射光角度、光的波长特性及叶片叶绿素含量之间的关系。实验表明,在RGB颜色系统中偏振现象对红光更加敏感,同时偏振度随叶绿素含量的增大而减小,当入射角为45°时偏振度最大。

We build a polarization information collection system used Duncan MS3100 3CCD camera with Kenko circular polarization glass.Using the system on cucumber leaf cultivated in green house, we study the relationship between Polarization level and the angle of incidence,light wavelength ,chlorophyll quantity of leaf and so on.The experiment statistics show that Polarization phenomenon is more active when the incidence light is red light; decreased with chlorophyll quantity of leaf increased and is biggest when the angle of incidence is forty-five degree.
