OPTICAL BASE PLATE ALIGNMENT

摘要

Alignment of two surfaces of two objects in a manufacturing process is achieved by determining a best fit orientation of the two objects with respect to each other using captured images reflected from the two surfaces. An image pattern is projected on a surface of each object, and a reflected image pattern is captured from the surface of each object. A reconstructed surface is determined from the captured reflected image patterns, and the two reconstructed surfaces are superimposed to determine a best fit orientation of the two objects with respect to each other. One or more movable portions of a base are actuated to align the two surfaces to each other to achieve the determined best fit orientation.
