초록
모바일 기반의 스마트 기기의 보급이 확대됨에 따라 교육 현장에서 이를 활용하는 사례가 증가하고 있는 추세이며, 가까운 장내에는 매우 중요한 교육용 기자재로서의 위치를 차지할 것으로 예측된다. 이러한 추세에 맞춰 교육과학기술부는 스마트 교육에 대한 중장기 추진 계획을 발표하였고 현재 추진을 준비 중에 있으며, 다양한 산업계 학계 연구 기관에서 관련 연구 결과물과 시제품들을 활발히 발표하고 있는 현실이다. 본 논문에서는 모바일 스마트 기기에 장착된 비디오카메라를 이용하여 촬영된 영상 내부에 포함된 문자를 인식하는 모듈을 구현하고 이를 응용하여, 교육환경에서 현실적으로 적용 가능한 학습용 시각 정보 인식 시스템에 관련한 설계 및 구현 방안을 제안하였다. 본 논문에서 제안한 학습용 시각 정보 인식 시스템은 비디오 영상취득, 영상 처리, 정보 추출, 지식 표현 등 4개의 모듈로 구성되었으며, 실제적인 예제를 통해 각 모듈을 설명 하였다.
Abstract
As propagation of mobile smart devices is widespread, it is an observable trend that the cases of utilizing them are increasing in the school programs, and it is also anticipated that they will be very important part of the educational equipment in near future. For this reason the department of education and science technology has announced a medium and long term project on the education with smart device, which is undergoing the preparation stage, and the various academic and industrial institutes have actively produced the related research results and the application prototypes. In this paper we propose a framework on design and implementation of a visual context recognition system for educational purpose usable in the school program by utilizing a module for recognition of the texts embedded in the image captured by video camera from mobile smart device. The system proposed in this paper is consisted of the four modules, such as, image acquisition, image processing, information extraction, and knowledge representation, which are explained in details with the practical examples.
