Disclosed is a stereoscopic optical inspection system. A computer uses the stereoscopic information to compute and correct for angular and distance misalignments between the unit-under-test and the inspection system. A feature of the optical system is the use of multiple high-resolution inspection cameras, in conjunction with a single stereoscopic reference camera. One example of a preferred embodiment is presented as an electro-optical inspection system for inspection and/or alignment of cathode-ray-tube displays and other video displays on a production assembly line.

A three-dimensional optical inspection and alignment system for electronically adjustable visual displays on a production assembly line comprising a rigid support, two cameras mounted on said support, said cameras oriented to have an overlapping field of view with each camera being calibrated to define two-dimensional locations in said overlapping field of view, computer means for identifying calibrated two-dimensional locations of said visual displays in said overlapping field of view from said cameras, determining three-dimensional coordinates of said visual displays in said field of view, and transforming three-dimensional coordinates to two-dimensional coordinates in an ideal viewpoint, and means for electronically adjusting said visual displays based on said two dimensional coordinates.
