IMAGE-BASED MOTION CHARACTERIZATION SYSTEM FOR A MOBILE DEVICE

Mobile devices and methods to facilitate the motion characterization of a welding element. A mobile device is used to capture video of a rotating welding element and the video is processed by a software application residing on the mobile device to determine a rate of rotation of the rotating welding element. The software application may perform further processing to determine a linear rate of motion as derived from the determined rate of rotation. The rate of rotation and/or the linear rate of motion may be displayed to a user of the mobile device on a display screen of the mobile device. Such methods may aid a user in calibrating a piece of welding equipment.
