YIELD DISTRIBUTION CALCULATION DEVICE AND YIELD DISTRIBUTION CALCULATION METHOD

摘要

This yield distribution calculation device is provided with an acquisition unit and a calculation unit. The acquisition unit acquires a detection value of a GNSS receiver which detects the position of a combine, a detection value of a straw amount sensor which detects the amount of straw transported by the combine, and a detection value of a grain sensor which detects the amount of grain harvested by the combine. The calculation unit calculates the yield distribution, which indicates the amount of grain according to position, on the basis of the grain amount detection value acquired by the acquisition unit and of the straw amount distribution, which is the change in the amount of straw according to position and time, obtained on the basis of the detection value of the amount of straw and position of the combine acquired by the acquisition unit.
