Abstract: An agricultural work machine, such as a self-propelled harvester, is provided. The agricultural work machine includes a crop gathering machine which has a crop cutting device, a crop collecting device and/or a crop feeding device, and at least one crop conveyor, and comprising an image processing system, a data output unit, and at least one sensor system assigned to the crop gathering machine for recording a crop flow in the crop gathering machine. The sensor system is coupled to the image processing system for transferring images. The image processing system processes a selection of available images, such as by pre-processing the images to be transferred in a first step, in a further step determining an optical flow and corresponding vector fields from the pre-processed images, and in a subsequent step deriving and assessing speed trends of the crop flow from the corresponding vector fields.

Abstract: A method for detecting interferences in a crop collecting system of an agricultural harvesting machine includes optically detecting a crop stream at the crop collection system. The method includes that the movement of an object over time in the crop stream is determined in the optically detected crop stream and, based on the determined movement of the object, an interference of the crop collection system is detected.
