摘要：
PROBLEM TO BE SOLVED: To accurately determine the discrimination of diseased trees (infected trees) from sound trees (uninfected trees) in a whole farm without requiring any special experience or skill. ! SOLUTION: A contraction determination method includes: an image acquisition step of acquiring a first satellite image as a monochrome satellite image obtained by imaging the whole region or partial region of a farm of para rubber trees and a second satellite image as a satellite image whose imaging range is the same as that of the first satellite image and which has sensitivity in at least a near-infrared region; a branch end specification step of specifying the position of a branch end of a para rubber tree from the first satellite image acquired in the image acquisition step; and a determination step of comparing the reflection intensity of the near-infrared region at the position of the second satellite image corresponding to the position of the branch end in the first satellite image specified by the branch end specification step with a predetermined threshold, and determining that the para rubber tree at the branch end is not diseased when the reflection intensity is less than the predetermined threshold, and determining that the para rubber tree at the branch end is diseased when the reflection intensity is equal to or more than the predetermined threshold. !
