  • Publication number: 20240126269
    Abstract: An upper point cloud estimator is configured to estimate a three-dimensional representation of the crop canopy based on collected stereo vision image data. A lower point cloud estimator is configured to estimate a ground three-dimensional representation or lower point of the ground based on the determined average. The electronic data processor is configured to determine one or more differences between the upper point cloud (or upper surface) of the crop canopy and a lower point cloud of the ground, where each difference is associated with a cell within a grid defined by the front region. The electronic data processor is capable of providing the differences to a data processing system to estimate a yield or differential yield for the front region, among other things.

  • Publication number: 20190353483
    Abstract: A method for planning a turn path of a vehicle includes monitoring coverage by the vehicle and/or a second vehicle, determining a turn start intersection point defined by an intersection of a first track path of a plurality of track paths and an inner headland pass at its corresponding edge, determining a turn end intersection point defined by an intersection of a second track path of the plurality of track paths and the inner headland pass at its corresponding edge, and creating a curved turn path from the turn start intersection point to the turn end intersection point based on coverage by the at least one of the vehicle and a second vehicle.
