COEFFICIENT CALCULATION DEVICE, COEFFICIENT CALCULATION METHOD, AND RECORDING MEDIUM IN WHICH COEFFICIENT CALCULATION PROGRAM IS RECORDED

摘要

Provided is a coefficient calculation device, etc., with which an accurate light-absorption coefficient pertaining to a given region can be calculated in a short period of time. A coefficient calculation device 401 has: a first coefficient calculation unit 402 for calculating, according to a prescribed calculation process, a light-absorption coefficient pertaining to a portion of partial regions from among a plurality of partial regions in an agricultural field; an association information creation unit 404 for creating association information that represents an association between the light-absorption coefficient calculated in relation to the portion of the partial regions and a feature value representing a feature pertaining to the portion of the partial regions; and a second coefficient calculation unit 403 for calculating, on the basis of the feature value pertaining to partial regions that are different from the portion of partial regions from among the plurality of partial regions and on the basis of the association information created by the association information creation means, the light-absorption coefficient pertaining to the different partial regions.
