Image processing system for soil characterization

摘要

A system processes images of soil using image processing techniques that help to reveal soil characteristics and differences between soil characteristics. The characteristics may be indicative of soil type, and the differences between soil characteristics help to identify where soil types change in a field. The system may determine management zones for a field based on the soil characteristics, e.g., by identifying multiple regions within a field, each management zone corresponding to similar soil characteristics. The system may communicate the management zones to devices in the field, to land appraisers, or to customers who use the results to manage the soil, as just a few examples.

1. A system comprising:
a memory comprising:
source image data comprising a region of ground soil to analyze, the source image data comprising near infrared (NIR) spectral data and Green spectral data;image processing instructions configured to process the NIR spectral data and the Green spectral data according to an SMI function:SMI=NIR-GreenNIR+Green; processing logic in communication with the memory, the processing logic configured to:
transform the source image data into a soil processed image by executing the image processing instructions on the source image data;store the soil processed image in the memory; anddelineate the soil processed image into discrete management zones, each management zone corresponding to a distinction in soil type indicated in the soil processed image after application of the SMI function.
