Abstract
An agricultural vehicle has a steering system providing steering signals and including an imaging device for imaging surroundings of the vehicle and an image processing device, the steering system operates to provide by the imaging device an image of the field, analyze the image to obtain texture information, assign to a plurality of areas of the image probability-values reflecting the likelihood that the respective area relates to a specific structure, assume at least one geometric property of the specific structure, and establish a most possible position parameter of the specific structure taking into account the probability-values and the assumed geometric property; and to provide a steering signal in accordance with the position parameter thus established.
