| Research Abstract |
We have proposed new close-range observation methods for field crops to assess yield components, nutrient condition and canopy productive structure using spectral radiometry and image engineering. Previously unexplored methods : nighttime measurement, middle infrared wavelength range, polarization image and continuous fixed-point spectral band image observations, and texture analysis, were discretely tested in field experiments. These methods had potential to non-destructively estimate, for example, plant height, leaf area, nitrogen density, biomass, growth stage, grain yield, leaf color and leaf inclination angle with high degrees of accuracy.
