Image-based inspection system for printed circuit boards, has controller to control operation of position-altering unit using representation of object that is generated by mapping unit

摘要

The system has an imaging unit connected to a position- altering unit that alters the position of an imaged object. A mapping unit (330) maps a surface of the object to generate a corresponding representation of the surface of the object. A controller (340) controls the operation of the position-altering unit using the representation of the object surface to ensure that the object lies within the focal plane. An Independent claim is also included for a method of an image-based inspection of an object.
