ABSTRACT:
Methods and arrangements are provided to efficiently use 3-D vision systems to measure selected features of objects that are semi-constrained in compartmented trays having a uniform geometric arrangement. The methods are particularly well suited for optimizing the 3-D measurement of leads on integrated circuit devices which are packaged in trays.
