Abstract: A method may include obtaining a set of events, of a set of pixels of a dynamic vision sensor, associated with an object; determining a set of voltages of the set of pixels, based on the set of events; generating a set of images, based on the set of voltages of the set of pixels; inputting the set of images into a first neural network configured to output a visual motion estimation of the object; inputting the set of images into a second neural network configured to output a confidence score of the visual motion estimation output by the first neural network; obtaining the visual motion estimation of the object and the confidence score of the visual motion estimation of the object, based on inputting the set of images into the first neural network and the second neural network; and providing the visual motion estimation of the object and the confidence score.

Abstract: An apparatus for filling a grain drill with grain includes a grain hopper and a manifold assembly. The hopper includes an open upper portion and a lower portion, and a conveying conduit communicates with an outlet in the lower portion of the hopper such that grain exits the outlet into the conduit. An air blower device is positioned at an end of the conveying conduit and forces pressurized air through the conduit and beneath the hopper outlet. The air in the conveying conduit entrains grain exiting the outlet and carries the grain along the conduit to the manifold assembly mounted on the planting apparatus. The grain and air pass into a manifold tube having a delivery slot and air exhaust apertures, with the grain passing through the slot into the grain drill and the air exiting through the exhaust apertures. The hopper, blower device and conduit may be formed as a stand alone unit which, during filling, is connected to the manifold assembly that is secured to the grain drill.
