数字图像处理技术,就是通过电子藕荷器CCD感应作物冠层的光反射和光吸收性质来形成影像记录,进而通过图像处理和分析技术获取不同营养状况下的光谱差异以实现整个诊断过程,具有方便快捷、准确及时和成本低廉的特点。茎瘤芥(榨菜)生长发育过程中氮素营养状况的实时诊断,也可通过数字图像处理技术实现。本文主要阐述了茎瘤芥氮素营养数字图像诊断技术的研究进展情况。
Digital image processing technology is to record the light reflection and light absorption properties of the crop canopy by the CCD sensor, and then to obtain the spectral difference under different nutritional status through image processing and analysis technology to achieve the whole diagnosis process. It is convenient and quick , Accurate and timely and cost-effective features. The real-time diagnosis of the status of nitrogen nutrition during the growth and development of the tumorous mustard mustard can also be realized by digital image processing technology. This article mainly expounds the research progress on the digital image diagnosis technology of the nitrogenous nutrition of the stem mustard.
