US Patent 9648807 Agricultural harvesting machine

An agricultural harvesting machine has a control arrangement including an optical sensor device for recording image series of a continuous main crop stream, an evaluation device for ascertaining a portion of damaged grain, a portion of non-grain in the main crop stream or both, on the basis of an image analysis of the recorded image series and a visualization device for displaying the portion of damaged grain and/or the portion of non-grain. The control arrangement cyclically records image series of the continuous main crop stream and, within a predetermined processing time after an image series has been recorded, displays a current portion of damaged grain, a current portion of non-grain or both, based on the image series.
