摘要

A method and system for crop health change monitoring is provided. The method includes acquiring a companion image of a crop growing within a field at a first point in time, acquiring a master image of the crop growing within the field at a second point in time, and computing, using a processor, vegetation indices using the master image and the companion image, determining, using the processor, regions of change within the master image using the vegetation indices and generating an alert indicative of a change in crop condition of the crop growing within the field, and communicating the alert indicative of the change in crop condition over a network to a computing device configured to receive the alert.

說(shuō)明書(shū)

If recent previous alerts were compared in step 350, a second threshold may also be applied. This threshold is a minimum percentage growth threshold, which requires the cumulative new alert area to be greater than a specified percentage of the cumulative area of the recent previously generated change regions compared in step 350. This percentage growth is computed as follows:

Change ? ? Area ? ? Percent ? ? Growth = New ? ? Change ? ? Area - Previous ? ? Change ?
