AbstractAbstract
Combines are used in fields to perform the complex operations necessary to effectively harvest crops. The swath width detection system would assist in providing maximum combine-head fill by capturing images of the field and using image processing techniques to extract valuable swath width measurements. As a result, farmers will be able to analyze their crop yields more precisely and potentially harvest at a faster rate.
