1. An agricultural harvesting machine comprising:
at least one work assembly configured to harvest a crop and to transport harvested material from the crop in a harvested material flow along a harvested material transport path through the agricultural harvesting machine; and
a monitoring assembly including at least one measuring system positioned on at least a part of the harvested material transport path and an evaluation device configured to determine at least one harvested material parameter;
wherein the at least one measuring system includes:
a first sensor, the first sensor comprising a passive optical sensor and positioned in the agricultural harvesting machine in order to generate image data indicative of light from a wavelength range in a first field of vision thereby depicting the harvested material within a first section of the harvested material flow; and
a second sensor, the second sensor comprising one or both of non-passive or non-optical and positioned in the agricultural harvesting machine in order to generate sensor data depicting the harvested material within a second section of the harvested material flow, wherein the first section and the second section at least partly overlap in an overlapping section; and
at least one transparent window positioned on the at least a part of the harvested material transport path and configured to contact on at least one side at least a part of the harvested material from the crop in the harvested material flow, the first sensor is configured to receive the light from the wavelength range through the at least one transparent window, wherein at least a part of the second sensor is positioned on the at least one transparent window and configured to sense the part of the harvested material that contacts the at least one transparent window;
wherein the evaluation device is configured to:
correlate at least a part of the image data for the overlapping section from the first sensor and at least a part of the sensor data for the overlapping section from the second sensor; and
determine, based on the correlation, the at least one harvested material parameter.
