Claim 10:
11. A self-propelled harvester comprising:
at least one of a threshing units, a separating device, or a cleaning device;
a display; and
a device configured to determine a portion of one or both of broken grain or non-grain components in a stream of harvested material, the device include:
a camera configured to generate images of the stream of harvested material; and
an evaluation unit configured to estimate the portion in an image generated by the camera;
wherein the evaluation unit comprises a first-order classifier configured to estimate a first parameter of the stream of harvested material, and a plurality of second-order classifiers assigned to various values of the first parameter to estimate the portion in a stream of harvested material that has the assigned parameter value;
wherein the evaluation unit is configured to:
estimate, using the first-order classifier, at least one value of the first parameter using one or more images of the camera; and
select the second-order classifier assigned to the at least one value of the first parameter;
estimate, using the selected second-order classifier, the portion of one or both of broken grain or non-grain components; and
perform at least one of:
cause modification of at least one aspect of the self-propelled harvester thereby modifying a process of the self-propelled harvester with respect to at least one of throughput, grain loss or the broken grain portion; or
cause display of the determined broken grain portions in order to allow a driver of the self-propelled harvester to make adaptations or modifications to operating parameters of the process of the self-propelled harvester.
