ABSTRACT:
A matrix array of objects, for example, semiconductor bars, is located on a carrier such as an XY table and the objects are successively brought into the field of view of a television camera to produce digitized video signals which are utilized in effecting precise alignment of the object with respect to a reference point. Following this alignment step, an electronic analysis is made, again on the basis of digitized video signals, to confirm the presence of an object in the aligned position, and that the object is complete. In the event a complete object is determined to be present in the aligned position, further analysis may be made, also on the basis of digitized video signals to determine whether the object has a surface identification mark indicating that the object is a reject.
