A method and apparatus for calibrating a measurement system are provided. The
method
and apparatus compensate not only for lamp variations, but also for camera and
optics variations. The system can be readily implemented and can be ported from
one measurement system to another. One embodiment of the improved calibration system
addresses the issue of variations between light sources by employing an automated
lamp calibration system. One method calibrates existing or new lamps to match an
established standard. In a preferred embodiment, the method will generate a reference
table, for a measurement system defined as the standard, to act as the reference
for all measurement systems. The reference table may be in the form of a data file
that may be subsequently copied to other measurement systems. The reference table
can then act as a global standard for other measurement systems, including future
systems not yet made.
