Measuring the Geometrical Parameters of Steel Billets during Molding Process Using Image Processing

This paper presents a designed system for measuring three dimensions (height, width and length) of steel billets during molding process. The system has been equipped with a Giga-Ethernet camera and an industrial computer (IPC). The billet is moved in front of the inspection system with an external moving mechanism. Image processing techniques and calibration are used to measure dimensions from the succeeding single view images
