Dual grain camera for a clean grain transporter of a combine harvester cleaning system

A combine harvester, the combine harvester comprising:

• a cleaning system that comprises:
• at least two cleaning sieves that separate grain kernels from grain chaff;
• at least two clean grain collectors arranged below respective cleaning sieves of the at least two cleaning sieves that receive the separated grain kernels therefrom;
• a clean grain transporter coupled to the at least two grain collectors and arranged to receive the separated grain kernels from the at least two grain collectors and transport the grain kernels towards a grain storage,
• the clean grain transporter simultaneously facilitates transport of a first crop stream comprising grain kernels coming from a first one of the at least two clean grain collectors and a second crop stream comprising grain kernels coming from a second one of the at least two clean grain collectors;
• and
• a camera system being arranged that alternately captures an image of a sample of the grain kernels in the first crop stream and an image of a sample of the grain kernels in the second crop stream, the camera system comprising at least one camera.

A method of operating a cleaning system of an agricultural vehicle, the method comprising:

• adapting an operational setting of a first cleaning sieve of at least two cleaning sieves of the cleaning system that separates grain kernels from grain chaff based on a first image of a sample of the grain kernels in a first crop stream being transported by a clean grain transporter that is:
• coupled to a first grain collector arranged below the first cleaning sieve, and
• arranged to receive separated grain kernels from the first grain collector and transport the grain kernels towards a grain storage;
• and
• adapting an operational setting of a second cleaning sieve of the at least two cleaning sieves based on a second image of a sample of the grain kernels in a second crop stream being transported by the clean grain transporter that is:
• coupled to a second grain collector arranged below the second cleaning sieve, and
• arranged to receive separated grain kernels from the second grain collector and transport the grain kernels towards the grain storage;
• wherein the first image and the second image are captured by a camera system being arranged that alternately captures the first image and the second image, the camera system comprising at least one camera.
