본 논문에서는 저조도 환경(야간 등)에서 광 무선 통신 링크를 구성할 때 레이저 비콘과 비전 시스템을 이용한 가시선 광 정렬 방법을 연구하였다. 이를 위해 5종의 레이저 마커를 각 통신 터미널을 식별하기 위한 비콘으로 사용하였다. 실내외에서 실화상 레이저 마커 이미지를 수집하고, YOLOX 모델의 전이학습을 통해 식별 성능을 분석하였다. 실험 결과, 개발된 모델의 비콘 식별 성능(mAP)은 92.1%였으며, 패턴별 결함 검출 성능(AP)은 91.0~94.2% 수준이었다. 이를 통해 개발된 모델이 저조도 환경에서 광 무선 링크 확보를 위한 보조 수단으로 활용될 수 있음을 확인하였다.
