Image-based inspection system including positioning compensation for non-planar targets

摘要

A image-based system for inspecting objects utilizes an imaging chain that defines a focal plane, a manipulator for translating and rotating either the object under inspection or the imaging chain, a surface mapping system that generates a representation of the surface of the object under inspection, and a controller that uses the representation of the surface of the object to control the manipulator so that a portion of the object under inspection lies within the focal plane of the imaging chain.
