Soil determination device, soil determination method, and recording medium for storing soil determination program

摘要

Provided is a soil quality determination device that can estimate soil type and density for various soil types. The soil determination device according to one aspect of the present invention is characterized by the frequency characteristics of the vibration of the target soil based on vibration data in which the vibration of the target soil that is the soil of the measurement target is measured by a vibration sensor that measures vibration. A frequency feature calculating means for calculating a frequency feature to be expressed, a moisture amount that is the amount of moisture contained in the target soil measured by a moisture meter that measures the amount of moisture contained in the soil, and the calculated frequency feature. In addition, the soil type of the target soil is stored using a soil model that represents the relationship between the moisture content and the frequency characteristics of a plurality of densities of soil types stored in the soil storage means. And soil quality determination means for estimating the density.
