Multispectral Imaging system for Nutritional Stressing

本课题拟设计一种低成本的多光谱成像系统，用于识别作物叶片和冠层微营养胁迫的早期症状。虽然系统最初将针对一种特定的植物物种，但这可以扩展到估计不同类型植物的总氮含量，镁，钾，磷酸盐和其他微量营养素。研究将包括设计一个低成本的基于cmos传感器的多光谱相机，合适的照明系统，基于SoC的嵌入式系统，一个适合营养压力分析的显示单元。

The research proposal is to design a lowcost multispectral imaging system, which can be used to identify early symptoms ofmicro nutritional stressing of crops at leaf level as well as canopy level. Thoughsystem will initially target one specific plant species, this could then be extended toestimate total nitrogen content, Magnesium, Potassium, Phosphate and other micronutrients of different types of plants. Research will include the design of a low costCMOS sensor based multispectral camera, suitable illumination system SoC basedembedded system, a display unit suitable for nutritional stressing analysis.
