Augmented crop loss sensing
A crop loss correction system receives one or more crop loss sensor signals that are indicative of crop lost by a harvesting machine. A correction component receives context information from a set of context sensing components to identify a context of the harvesting machine. The correction component corrects the crop loss sensor signals, based upon the context information, to obtain a corrected loss signal indicative of the sensed crop loss, corrected based on the mobile machine context. The corrected loss signal is output to an output device.
