Abstract
A system, apparatus, method, and computer program product for evaluating an object disposed on an upper surface of an object holder. At least one first frame representing a captured portion of the object is acquired, while the object holder is positioned at each of multiple locations. At least one second frame representing a captured portion of at least one other surface of the object holder is acquired, while the object holder is positioned at each of the locations. At least one spatial characteristic associated with the captured portion of the object is determined based on at least one of the acquired frames. Values of multiple optical markers captured in each second frame are determined, where at least two of the optical markers have different characteristics. At least one of coordinates associated with the values and an orientation of the captured portion of the at least one other surface are determined.
