摘要
叶片水分对一定波长的红外辐射具有强烈的吸收作用。叶片含水率不同,对辐射的吸收能量也不同。为此,根据该原理设计叶片水分传感器,通过测量反射和透射的红外辐射能量的大小,并将BP神经网络技术融入计算过程中,实现方便快捷的作物叶片含水量检测。
Leaves moisture has a strong absorption to a certain wavelength of infrared radiation.The content of moisture in leaf is different,energy absorption to the radiation is different,According to this principle,this paper design a sort of optical leaf moisture sensor,by measuring the infrared light intensity of transmission and reflection and integrating BP neural network technology into this design,to achieve fast and convenient measurement of moisture content in plant leaves.
