Abstract: A system for optical assessment of crop in a harvesting machine comprising: a camera configured to record an image of the crop; and an image processing system configured to receive the supplied image from the camera and a reference image and generate an output value based on a degree of similarity between the reference image and the supplied image.

Abstract: A mobile agricultural machine includes a row unit having a furrow opener mounted to the row unit and configured to engage a surface of ground over which the mobile agricultural machine travels to open a furrow in the ground. A furrow closer is mounted to the row unit behind the furrow opener relative to a direction of travel of the mobile agricultural machine and configured to engage the surface of the ground to close the furrow. A furrow sensor system is mounted to the row unit and configured to sense characteristics relative to the furrow opened by the furrow opener and generate a sensor signal indicative of the characteristics. The mobile agricultural machine can further include a control system configured to determine a furrow quality metric corresponding to the furrow sensed by the furrow sensor system based on the sensor signal and generate an action signal to control an action of the mobile agricultural machine based on the furrow quality metric.
