| Research Abstract |
I developed how can to measure rapidly the canopy leaf color of rice plant according to the leaf color-scale.
The precision of the leaf color sensor which I manufactured as an experimentwas superior to the human decision precision.
This leaf color sensor could estimate the leaf color even at not only order light but also oblique light and the backlight.
As for the experiment system that carried this leaf color sensor on the measurringvehicle, the leaf color of canopy rice plant, could be measured at on-line continuesly.
I propose the probavility that the development of the system which is the automatic on-the-go fertiliser spreader without over manure.
