摘要
PROBLEM TO BE SOLVED: To provide apparatus for estimating normal stock ratio, which early predicts reduction in harvest amount due to missing stock and predicts the yield of crops with high accuracy.SOLUTION: According to the present invention, an apparatus comprises: a prediction target-cropping setting section 21-1 for setting a cropping ID of a prediction target: an image data-analyzing section 21-2 for calculating a vegetation index representative value of a field of prediction target-cropping on an image photographing date; a growth model-adapting section 21-3 for calculating a representative value of the estimated vegetation index; a growing stage-estimating section 21-4 for estimating a growing stage at every elapse of days from a cropping start date, an image data-selecting section 21-6 for selecting image data of a second resolution; an image data-analyzing section 21-7 for calculating a multidimensional vector for each pixel of the field of prediction target cropping in the image of the second resolution; and a normal stock ratio-estimating section 21-8 for specifying, from clusters obtained by classifying multidimensional vectors, a cluster in which the pixels of the normal stock portion are classified, and estimating a normal stock ratio in the field from the ratio of the pixels belonging to the specified cluster to all pixels in the field.SELECTED DRAWING: Figure 1B
