1. A crop analysis system, comprising:
an imaging array configured to acquire a set of images of a crop;
a computing device having a processor executing computer-readable instructions to configure the computing device to:
identify a condition of the crop based on the set of images acquired by the imaging array, wherein the computing device is further configured to select a feature of an image of the set of images corresponding to a portion of the crop and analyze the pixels of the image associated with the portion of the crop to identify the condition of the crop, and wherein the computing device is further configured to select, as the feature of the image corresponding to the portion of the crop, at least one mature leaf with a broad surface generally directed to the imaging array, and wherein the computing device is further configured to select one or more positions on the portion of the crop selected and analyze respective sets of pixels associated with the one or more positions selected to provide respective measurements for identifying the condition of the crop; and
signal an agricultural machine to perform an action based on the condition identified,
wherein the system is coupled to an agricultural vehicle and wherein the imaging array is further configured to acquire the set of images as the agricultural vehicle traverses a field including the crop.
