基于最小二乘法的油菜叶片叶绿素含量检测系统的设计

Design of Chlorophyll Content Detection System Based on Least-square Algorithm

提出了一种通过检测光谱强度来确定油菜叶叶绿素含量信息的系统.根据光谱吸光度与油菜叶片叶绿素含量具有显著相关性的原理,利用AT89C51单片机对透射后的光谱强度进行转换、用最小二乘法进行数据分析,进而判断叶绿素的含量.该系统价格便宜、结构简单,并能够保存结果.

This paper proposes a kind of non-contact detection system for chlorophyll level of rape leaf through the detecting of spectral intensity.According to the spectra was found significant for predictive modeling of chlorophyll level of rape leaf.The system transformed the spectra to electricity by AT89C51,then judged chlorophyll level and analyzed data based on least-square algorithm.The system is cheap,simple and can save the results.
