Overview: A feasible solution to the problem of measuring and aligning automatically video color monitors in industrial manufacturing process is considered in this paper. The system is comprised of an integrated mechanical and software environment, and a digital video system is used as a feedback sensing for acquiring "In front of screen" image. Digital image processing techniques are used to pre-process the acquired image and digital image computational methods are employed to analyze screen geometric patterns, such as geometric distortion, rotation, vertical and horizontal centralization, and dimension (height and width). For monitors with total digital control the system can check and adjust automatically the circuits that determine screen geometry by using IC bus.
