Measurement of growth parameters used for crop lodging risk diagnosis Recommended spot presentation method, lodging risk diagnosis method, and information providing device

摘要

PROBLEM TO BE SOLVED: To prompt a user to measure a minimum necessary growth parameter by presenting a region suitable for measuring a growth parameter, and to accurately perform a lodging risk diagnosis based on an actually measured value. Improve the accuracy of lodging risk diagnosis by presenting recommended measurement spots with stable growth. SOLUTION: The recommended spot presentation method for measuring growth parameters used for diagnosing the lodging risk of crops cultivated in a field is to determine the growth degree of the crop based on the data of the field image obtained by photographing the field from the sky. A growth index calculation step of obtaining the growth index to be shown for each pixel of the field image, and a standard region identification step of specifying a plurality of standard regions in which the growth index is within the standard range based on the growth index of each pixel. A measurement recommended spot specifying step for specifying any of the plurality of standard regions as measurement recommended spots based on the respective areas of at least a plurality of standard regions, and an information output step for outputting information indicating the specified measurement recommended spots.
