Apparatus and processes for corn moisture analysis and prediction of optimum harvest date

摘要

Methods and apparatus are provided for determining moisture content of corn. In one example, a method includes processing a captured image of an ear of corn using a threshold value to create a segmented binary image comprising a first plurality of blobs, determining at least one characteristic of a plurality of corn kernels represented by the first plurality of blobs, and estimating a moisture value for the ear of corn based on the at least one characteristic of the plurality of corn kernels. In some embodiments, the method includes generating a luminance intensity profile across a region of the captured image containing at least one corn kernel in the plurality of corn kernels, computing a derivative of the luminance intensity profile; an determining, with reference to the derivative of the luminance intensity profile, a location of a boundary of the at least one corn kernel.
