Abstract: The purpose of the project was to develop a high speed, high accuracy measuring device
to aid the engineering technology department at Western Carolina University. When
something requires measurement with a high degree of accuracy a coordinate measuring
machine is used. This process can be very time consuming especially when multiple
iterations are required. A machine vision system is capable of making the same type of
measurements in a matter of seconds rather than minutes.
This study covers the development and testing of a machine vision system. Several tests
were conducted to help develop and improve the system through changes to the test
fixture, lighting, programming, and test object. The results of these tests are only valid for
the specific set-up and equipment used, and cannot be transferred to any other system.
Even slight changes to the equipment during testing showed significant changes in the
data being gathered. This contributed to the final conclusion that the measurements
gathered by the machine vision system are not comparable to those of the coordinate
measuring machine at any level of accuracy. Improvements to the machine vision system
setup must be made to improve accuracy.
