1. A method of controlling a load wrapping apparatus of the type configured to wrap a load on a load support with packaging material dispensed from a packaging material dispenser through relative rotation between the packaging material dispenser and the load support, the method comprising:
sensing a plurality of points on a plurality of surfaces of the load using one or more sensors directed at the load, wherein at least a subset of the plurality of points are sensed by a first sensor positioned to sense one or more upwardly-facing surfaces of the load;
generating a surface model of at least a portion of the load based upon the sensed plurality of points, wherein the generated surface model identifies a top surface topography comprising a plurality of elevations for the load defined by the subset of points sensed on the one or more upwardly-facing surfaces of the load; and
controlling one or more control parameters for the load wrapping apparatus when wrapping the load based upon the generated surface model.
