Claim 8:
9. A crop growth stage determination method, comprising:
inputting first images obtained by image capturing crops in a manner such that crop shapes are extractable are input based on satisfying preset image-capturing conditions;
inputting growth stages each indicating a level of physiological growth of the crops is input for each of the first images;
constructing a learned model by performing deep learning to associate images of the crops and growth stages of the crops based on the input first images and the input growth stage;
inputting a second image obtained by image capturing crops a growth stage of which is unknown, in a manner such that crop-shapes are extractable based on satisfying the preset image-capturing conditions:
determining the growth stage for the input second image based on the learned model; and
outputting the determined growth stag;
wherein the crops are paddy rice, and
the method includes performing deep learning to associate images, from which shapes of the paddy rice are extractable, with growth stages including panicle initiation, the panicle initiation being a time point at which differentiation of a young panicle wrapped in a leaf sheath starts.
