Abstract

A smart factory is a key industrial application introduced by the 4th industrial revolution. The automatic guided vehicle (AGV) is one of the technology realizing smart factory, but the development cost is high due to its early stage of technology. Although developing a low-cost AGV requires a lot of data, it has limited data acquisition capability because of the limited storage and the AGV movement. Hence, we propose a development environment using Bluetooth to collect data and design a lane detector. The proposed lane detector shows a high lane detection ratio regardless of light variation and a shade.

스마트공장은 4차 산업혁명으로 잉태되는 핵심산업 중 하나이다. 스마트공장을 실현하기 위한 기술 중 무인운반차 기술은 초기 단계로 이를 구현하기 위해선 높은 비용이 필요하다. 저비용 AGV를 개발하기 위해선 많은 데이터가 요구되지만, 저장공간이 부족하고 AGV가 이동하므로 데이터 수집 방법이 제한된다. 따라서 본 논문에서는 블루투스를 이용한 무선통신 기반 개발환경을 구축하고 이를 통해 수집한 데이터를 이용하여 차선 검출기를 개발하고자 한다. 이렇게 개발된 차선 검출기는 조명 환경의 변화나 그림자 유무와 관계없이 높은 차선 인식률을 보인다.
