Abstract
A cotton harvester estimates the mass of cotton as it is harvested using sensor devices and compares the mass of each module against the estimated mass of the module as determined by the sensors so that a calibration factor may be determined and actively updated for more accurate crop yield determination. The mass flow for a specific module is accumulated and processed during harvesting using a base calibration factor and the module is weighed and compared against the expected mass using the base calibration factor to develop a candidate updated calibration factor. The base calibration factor is selectively replaced by the candidate updated calibration factor for processing a subsequent module based on machine feedback information relating to the operation of the harvester. Harvested crop data determined using the calibration factor is used to generate highly accurate yield maps.
