Spectral Detector Design for Nitrogen and Moisture of Rape

Abstract:

Article Preview

For the four spectral bands of rape canopy leaf which is sensitive to nitrogen and moisture contents, a reflection spectral detector was designed to measure nitrogen and moisture of rape, constituted by the adjustable light, filter module, passive detection array, signal conditioning and acquisition modules. Further, a test was carried on to verify performance by several different reflectivity of the plates and four levels of nitrogen and moisture rape. The result shows that correlation coefficient between the contents of nitrogen, moisture and output of detector was 0.78, relative error of the detector was 9.5%, accuracy of sample classification was 65%.
