System and method for crop health monitoring

摘要

A method for monitoring crop health of a geographic region includes receiving an image comprising a set of image elements, the image corresponding to a time unit, mapping an image element of the set of image elements to a geographic sub-region of the geographic region, determining a geographic region performance value for the image element, determining a geographic region performance value change, and identifying a crop health anomaly based on the geographic region performance change and an expected geographic region performance value change. Determining the geographic region performance value for the image element can include determining a vegetative performance value for the image element, mapping the image element to a crop type, and normalizing the vegetative performance value.

1. A method for monitoring crop health of a geographic region, the method comprising:
receiving a first image comprising a set of image elements, the first image corresponding to a first instance of a first recurrent time unit; mapping a first image element of the set of image elements to a geographic sub-region of the geographic region; generating a vegetative performance value for the first image element; mapping the first image element to a crop type; normalizing the vegetative performance value with respect to remaining vegetative performance values associated with a subset of the set of image elements, wherein the subset of image elements is mapped to the crop type; generating a first geographic region performance value for the first image element based on the normalization of the vegetative performance value; calculating an actual geographic region performance value change between the first geographic region performance value and a second geographic region performance value, the second geographic region performance value associated with a second image element of a second image, the second image corresponding to a first instance of a second recurrent time unit, wherein the second image element is mapped to the geographic sub-region; determining an expected geographic region performance value change based on a third and a fourth geographic region performance value, wherein the third geographic performance value is associated with a third image corresponding to a second instance of the first recurrent time unit, and wherein the fourth geographic region is associated with a fourth image corresponding to a second instance of the second recurrent time unit; defining the geographic sub-region as an anomalous geographic sub-region of a set of anomalous geographic sub-regions, in response to the actual geographic region performance value change differing beyond a predetermined threshold from the expected geographic region performance value change for the geographic sub-region; and identifying a crop health anomaly based on the set of anomalous geographic sub-regions.
