Windrow width and volumetric spread measurement of mower implement

A mower implement comprising:

• a main frame;
• a cutter assembly coupled to the main frame and operable to cut a crop material and form the cut crop material into a windrow;
• a hyperspectral sensor coupled to the main frame and configured to receive reflectance from a target area disposed rearward of the cutter assembly and including the windrow, and to generate a signal indicative of light spectrums of the target area;
• a controller having a processor and a memory having a windrow distribution algorithm stored therein, wherein the processor is operable to execute the windrow distribution algorithm to:
• receive the signal indicative of the light spectrums of the target area from the hyperspectral sensor;
• calculate a normalized difference index based on the signal indicative of the light spectrums of the target area;
• estimate a volumetric spread of the windrow;
• and
• control a machine system based on the volumetric spread, the machine system includes one of a display, an actuator, and a drivetrain component;
• wherein the processor is operable to execute the windrow distribution algorithm to define, simultaneously, a row of subregions spanning across a width of the windrow or a width of the target area covering the windrow based on the signal indicative of the light spectrums of the target area, and to assign values of the normalized difference index to the respective subregions to estimate the volumetric spread of the windrow.
