Abstract
A method and system for manipulating a target item supported on a substantially horizontal support surface supporting a configuration of substantially identical items are provided. The system includes at least one light source configured to illuminate at least one surface including a top surface of the items to obtain backscattered illumination. A volumetric sensor such as a 2-D/3-D sensor is configured to sense the backscattered illumination to obtain at least one depth image and at least one appearance image. At least one processor is configured to determine geometric information and appearance information from the images. The at least one processor is also configured to generate a plurality of hypotheses and surprisals of the information and to rank the hypotheses based on their surprisals. In one embodiment, the best hypothesis is selected and the item is manipulated or picked from a pallet by a vision-guided robot based on the best hypothesis.
