摘要
在模式识别理论分析基础上，依据光源光谱、ＣＣＤ摄象元件光谱响应以及作物籽粒表面反射率光谱特性，得出籽粒黑白图象识别系统最佳光源为单色光，其波长为使两待识籽粒反射率光谱差值与ＣＣＤ光谱响应二者的串联响应最大的波长。根据测得的正常和带紫斑病大豆的反射率光谱。
On the basis of pattern recognition analysis and in the light of the spectrum of light source, the spectral response of CCD sensor as well as the spectral reflectance of kernels, it is found that for the black and white image recognition system the optimum light source is a monochromatic light,the wave length of which is that rendering the series response of the difference between the spectral reflectances of two objects and the CCD sensor spectral response maximum. The wave length of light source for the discrimination of the infected from the normal soybeans is calculated from the measurement data of their spectral reflectance.
