Threshing control system

An agricultural harvester comprising:

• a threshing system including at least one threshing rotor or threshing drum, cooperatively arranged in parallel to an opposing threshing concave, wherein the threshing rotor or the threshing drum in combination with the opposing threshing concave together configured to thresh crop material received from a feeder housing of the agricultural harvester causing smaller elements of the crop material to be discharged through perforations in the threshing concave while larger elements of the crop material are transferred by the threshing rotor towards a chopper for chopping the larger elements into smaller pieces,
• a camera positioned at a location that faces a rear end of the threshing rotor or the threshing drum for obtaining images of a crop flow at that location,
• a controller operatively coupled to the camera and configured that:
• receives the obtained images from the camera,
• processes the images to detect grain ears therein, and derives therefrom at least one physical property of the detected grain ears, and
• controls an operational setting of the threshing system based on the derived at least one physical property, wherein the controlled operational setting is a concave clearance between an outer radius of the threshing rotor or threshing drum and an inner surface of the threshing concave, a concave opening of the threshing concave, and a rotational speed of the threshing rotor or threshing drum.

• a residue chopper positioned at the rear end, wherein in a chopper mode of the agricultural harvester the larger elements of the crop material are delivered to the chopper for chopping the larger elements of the crop material into smaller pieces, and wherein in a thresher mode of the agricultural harvester the larger elements of the crop material are guided along a bypass route that bypasses the residue chopper;
• a camera assembly for obtaining images of a crop flow at a first location residing at an outlet of the chopper and a second location residing along said bypass route,
• a controller operatively coupled to the camera assembly that:
• receives the obtained images from the camera assembly,
• processes the images to detect grain ears therein, and derives therefrom at least one physical property of the detected grain ears, and
• controls an operational setting of the threshing system based on the derived at least one physical property.
