Abstract

In today's rapidly growing contemporary society, there is a tendency for demand to automate production processes by utilizing the vision system. In general, image recognition is mainly concerned with embossed characters such as license plates, and research on recognition of intaglio characters is very limited. Especially, intaglio characters, which are marked on rubber related products such as tire surfaces, have difficulty in recognizing characters or numbers through image because the difference in brightness with surrounding is not so large. In this paper, we propose a system to improve the recognition rate of characters marked on intaglio rubber products such as tire surfaces. Also, it can be applied flexibly according to the lighting environment. Through the proposed system, production and inventory management and defect detection can be processed quickly by applying to the production process of tire and rubber products.

빠르게 성장하고 있는 현대 사회에서 생산 공정에 비전 시스템을 활용하여 자동화 하고자 하는 수요가 급증하고 있는 추세이다. 일반적으로 영상 인식은 주로 자동차 번호판과 같은 양각 문자에 대한 연구가 대부분으로, 음각 문자 인식에 대한 연구가 매우 미미한 상황이다. 특히 타이어 표면과 같은 고무 관련 제품에 마킹 되어 있는 음각 문자들은 주변과의 명도 차이가 크지 않기에 문자나 숫자를 영상을 통하여 인식하기에 매우 어려움을 가지고 있다. 이에 본 논문에서는 타이어 표면과 같은 고무 제품에 음각으로 마킹 되어 있는 문자의 인식률을 향상시키기 위한 시스템을 제안한 것으로, 조명의 환경에 따라 유연하게 적용할 수 있다. 제안 시스템을 통하여 타이어 및 고무 제품들의 생산 공정에 적용하면 생산 및 재고 관리와 불량 검출을 신속하게 처리할 수 있어 생산 효율성이 향상될 것으로 기대된다.
