Abstract
Methods and systems for analyzing a field. The methods and systems acquire a thermal image indicative of thermal energy emitted by the soil and/or plants in the field and process the thermal image to assess variations in certain characteristics of the soil and/or plants.
Claims8
A method of analyzing a field, the method comprising:
- positioning an imaging system in an aircraft, the imaging system comprising a long-wave thermal imaging camera operable to collect thermal energy emitted by plants in a long-wave infrared spectrum of about 7 to about 14 micrometers;
- acquiring with the long-wave thermal imaging camera a first aerial thermal image of at least a portion of the field that contains plants while the aircraft is in flight over the field, wherein the first aerial thermal image comprises thermal energy emitted by the plants in the long-wave infrared spectrum and pixels indicating different levels of thermal energy emitted in the long-wave infrared spectrum by the plants within the portion of the field while the aircraft is in flight over the field;
- processing the first aerial thermal image to assess relative variations in temperatures among the plants within the portion of the field by assessing variations in the pixels of the first aerial thermal image;
- acquiring with the long-wave thermal imaging camera a second aerial thermal image of the portion of the field that is indicative of the thermal energy emitted in the long-wave infrared spectrum by the plants within the portion of the field while the aircraft is in flight over the field at a time after the first aerial thermal image is acquired;
- processing the second aerial thermal image to assess variations in temperatures among the plants within the portion of the field by assessing variations in the pixels of the second aerial thermal image;
- and
- comparing the first aerial thermal image with the second aerial thermal image to assess the health or growth of the plants over a time period between when the first aerial thermal image was acquired and the time when the second aerial thermal image was acquired.

A system for analyzing a field, the system comprising:
- an imaging system in an aircraft, the imaging system comprising a long-wave thermal imaging camera operable to collect thermal energy emitted by plants in a long-wave infrared spectrum of about 7 to about 14 micrometers and acquire a first aerial thermal image and a later second aerial thermal image of at least a portion of the field that contains plants while the aircraft is in flight over the field, wherein each of the first and second aerial thermal images comprises thermal energy emitted by the plants in the long-wave infrared spectrum and pixels indicating different levels of thermal energy emitted in the long-wave infrared spectrum by the plants within the portion of the field while the aircraft is in flight over the field;
- means for processing the first and second aerial thermal images to assess variations in temperatures among the plants within the portion of the field by assessing variations in the pixels of the first and second aerial thermal images;
- and
- means for comparing the first aerial thermal image with the second aerial thermal image to assess the health or growth of the plants over a time period between when the first aerial thermal image was acquired and the time when the second aerial thermal image was acquired.
