A method of controlling a material handling device (20) and a sensor (62) to provide a profile of a work area comprising a group of a plurality of objects (28) positioned with respect to the material handling device (20). The method includes the first step of operating the material handling device (20) to move the sensor (62) to a plurality of positions defining a scanning path (64) with respect to the work area. Next, at selected positions, the sensor (62) is used to measure distances to a surface within the work area. Sets of coordinate values for the selected positions are stored in association with respective measured distances. Thereafter, the profile of the work area is determined in response to the stored distance values. The profile of the work area may include information with respect to the presence and absence of objects in the group, the location of an edge (70) of an object in the group, the location of the first object to be processed in the group, the presence of dunnage (86) in association with the objects. |
