Research output: Contribution to journalArticlepeer-review


An automated kernel positioning device for a computer vision system was developed. A vibratory bowl feeder metered kernels to a conveyor which was equipped with a positioning device to place kernels under a computer vision camera on an image platform near the center of the lighting chamber. A controller was developed to position and remove kernels. The controller was interfaced to the image processing computer to coordinate image processing functions with handling processes. The system used photosensors to identify the position of kernels throughout the path of the handling equipment. The arrangement of the sensors provided status information which allowed self-diagnosis and correction of extra kernels within the path. The controller provided corrective measures for failures of the handling equipment. The controller and kernel positioning device provided error-free mechanical operation 99% of the time.
