Abstract
A new method and apparatus for fabrication or alignment of fixtures, jigs and structures is disclosed. The invention uses target points on one or more details which are referenced to the overall structure via targets on the details. These targets are monitored by a TV camera unit which is alternatively interfaced to a display for the human operator or a robot to provide position data. The interface may include input from a CAD system which allows display on robot coordinates to be offset by design data of the structure or a part to be located on it. While mainly envisioned for assistance in constructing fixtures for automobile assembly, the disclosed invention is widely useable for all types of construction including aircraft, bridges, boats, buses, houses, buildings and the like. A means for improving resolution of automatically servoed camera based systems is also disclosed.
