ABSTRACT:
A motion detection system, and more particularly, a non-contact, movement-measurement and position-tracking device, and a method of applying the device on long, non-textured or regularly textured metal objects at an elevated temperature are invented. The invention takes advantage of the oxidation marks, also known as scale, on the surface of the metal object to track the motion. The oxidation marks are typically random and irregular, providing a means for pattern tracking using imaging technologies.
