Paper Abstract

Owing to the effect of the high temperature, complex illumination and bad-imaging environment, there are a lot of difficulties in the target of character detection algorithm in complex background. For the requirement of identification and trace of steel billet in the procedure of manufacture and management, the ends of steel billets are all printed a series of digital characters before they are transported to furnace. Owing to the high temperature and the complicated-imaging background, the character detection of digital characters at ends of steel billets is more difficult than general character detection. For the former methods dissatisfied with practical demands, a method using an improved OTSU algorithm and extracted the target character by projection in this paper.
