Control system of agricultural vehicle with goods carrier, agricultural vehicle, and method of controlling goods carrier of agricultural vehicle

A control system controlling a goods carrier of an agricultural vehicle for conveying goods to a target area, has a 3D imaging device providing frames imaging the target area, a data processor and a memory. The control system derives information from the frames and operates to obtain a reference frame comprising 3D information about the pose of the target area, identify a plurality of characteristic points of the target area in the reference frame, obtain a new frame, analyze the new frame to identify a plurality of characteristic points, search and match characteristic points in the reference frame and the new frame, analyze pairs of matched characteristic points to establish a group of pairs showing a common change of pose between the reference frame and the new frame, and provide a signal taking into account results of the latter analysis.
