An adaptive pattern recognition and detection technique for target image of continuous casting with length cutting

In production process of steel making and continuous casting, on-line length measurement and fixed length of continuous casting slab are very important. Starting from increasing the yield of length cutting for continuous casting products, on the base of cutting measurement about non-contact automatic cutting length. Such problems were introduced as abrasion and slippage, which existed in measure-roller of continuous casting slab length control, and a technology of digital image adaptive pattern recognition for target image was given to realize segmentation and recognition in image region of continuous casting slab and complex field interference, this paper presents preconditioning technique of image noise for billet production field. Image processing for complex production environment which provides reference for length-fixing cutting about plate and heavy rail production in practice.
