This paper describes the development of a cost-effective and reliable automated method for inspection spacers on the dielectric surface of AC Plasma display panels. The system generates 3D profiles of spacers using a light-section microscope in conjunction with a PC-based vision system. Structured lighting, a video camera and frame grabber are used to capture images for computer analysis.
