An automatic vision guidance system for an agricultural vehicle is disclosed and described. The vision guidance system uses a K-means clustering algorithm in image processing to distinguish between crop and non-crop features. The vision guidance system utilizes moment algorithms to determine the location and orientation of crop rows, from which desired wheel angles are determined and steering is commanded. The vision guidance system may adjust the location and orientation of visually determined crop rows according to a predetermined distance between crop rows. Further, the vision guidance system may utilize a redundant number of regions of interest in determining crop row locations and orientations.

1. An automatic guidance system for an agricultural vehicle, the guidance system comprising:an electromagnetic sensor for gathering information about field characteristics, the electromagnetic sensor configured to provide a signal representative of the field characteristics, the signal representative of pixels of an image; a controller configured to receive the digital signal representative of the field characteristics; and a trajectory planner configured to plan a trajectory and to determine a steering angle correction for the vehicle based on the digital signal representative of the field characteristics, wherein the trajectory planner estimates path points between a location in the image and a reference point on the vehicle.
