Crop quality sensor based on specular reflectance

A crop quality sensor, comprising an illumination source, an imaging device, and a processor executing application software. The illumination source is shone onto a crop sample, and an image is taken with the imaging device of the illuminated crop sample.

CONTROLLER FOR AN AGRICULTURAL HARVESTER

A controller for controlling a harvesting performance of an agricultural harvester. The controller receives automation settings, selected by an operator via a human-machine interface. The controller also receives data from on-board harvester sensors. The controller defines a target value for quality parameters based on the automation settings, and determines a current value of each of the quality parameters in dependence on the crop sensor data. The controller determines an actuator setting for actuators of the agricultural harvester when the current value of one or more of the plurality of quality parameters differs by greater than an acceptable amount from the associated target value. The actuator setting is determined in dependence on the automation settings and the target value. The controller controls the actuators to achieve the determined actuator setting.
