Abstract

Provided are a soil estimation device, a soil estimation method and a program that are capable of improving the accuracy of estimation of a state in soil without increasing the number of sensors that detect the state in the soil. The soil estimation device 100 is provided with an estimated model generation unit 10 . The estimated model generation unit 10 generates an estimated model based on at least one among geographical information that specifies a geographical feature of a field of interest and soil distribution information that specifies a soil distribution in the field. The estimated model is a model for estimating, from a measured value that indicates the state in the soil at one location within the field, the state in the soil at a location other than the one location.

First claim

The invention claimed is:

1. A soil estimation device, comprising:
at least one memory storing instructions; and
at least one processor configured to execute the instructions to:
generate an estimated model based on at least one from among geographical information that specifies a geographical feature of a field of interest and soil distribution information that specifies a soil distribution in the field;
estimate, from a measured value that indicates a state in soil at one location within the field, a state in the soil at another location different from the one location; and
predict an inflow amount and an outflow amount of moisture in the soil for each section obtained by dividing the field into a plurality of parts, and generate the estimated model indicating a relative relationship of moisture content in the soil in each section.

2. The soil estimation device according to claim 1 , wherein the at least one processor is further configured to:
acquire the measured value of the moisture in the soil of the field;
based on the measured value and the estimated model, estimate the moisture content in the soil; and
generate image data for visualizing the estimated moisture content in the soil.

3. The soil estimation device according to claim 2 ,
wherein the at least one processor is further configured to generate the image data such that, for each block obtained by dividing the field into the plurality of parts, a pattern in the block differs according to the moisture content.

4. The soil estimation device according to claim 2 ,
wherein the at least one processor is further configured to generate image data in which, for each block obtained by dividing the field into the plurality of parts, a shade of color in the block is represented according to the moisture content.

5. The soil estimation device according to claim 1 ,
wherein the geographical information is information that specifies a state of a slope of a surface of the field, and
the soil distribution information is information that specifies a distribution state of a component that constitutes the soil.

6. A soil estimation method, performed by a computer, the method comprising:
generate an estimated model based on at least one from among geographical information that specifies a geographical feature of a field of interest and soil distribution information that specifies a soil distribution in the field;
based on the estimated model, estimating, from a measured value that indicates a state in a soil at one location within the field, a state in the soil at another location different from the one location; and
predicting an inflow amount and an outflow amount of moisture in the soil for each section obtained by dividing the field into a plurality of parts, and generate the estimated model indicating a relative relationship of moisture content in the soil in each section.

7. A non-transitory computer-readable recording medium having recorded thereon a computer program including a command causing a computer to:
generate an estimated model based on at least one from among geographical information that specifies a geographical feature of a field of interest and soil distribution information that specifies a soil distribution in the field;
based on the estimated model, estimate, from a measured value that indicates a state in the soil at one location within the field, a state in the soil at another location different from the one location; and
predict an inflow amount and an outflow amount of moisture in the soil for each section obtained by dividing the field into a plurality of parts, and generate the estimated model indicating a relative relationship of moisture content in the soil in each section.
