Abstract

In this paper, a blind person using a white cane as an adjunct of the things available sensing technology has been implemented. Sensing technology to implement things ultrasonic sensors and a webcam was used to process the data from the server computer. Ultrasonic sensors detect objects within 4meter people distinguish between those things that if the results based on the results will sound off. In this study, ultrasonic sensors, object recognition and human perception with the introduction of techniques and technologies developed for detecting objects in the lives of the visually impaired is expected to be greater usability.

본 논문에서는 초음파센서와 버튼들로 구성된 초음파 단말기와 카메라 센서를 융합한 시각 장애인들을 위한 사물 감지 기술을 소개한다. 초음파 단말기의 초음파센서로 4m 이내의 사물을 감지하면 웹캠으로 사물을 촬영하고 얼굴검출과정을 통해 그 사물이 장애물인지 사람인지 구별한다. 검출결과를 음성으로 사용자에게 이어폰을 통하여 알려준다. 본 논문에서 개발된 기술을 통하여 시각장애인이 흰 지팡이와 같이 보조적으로 사용이 가능하며, 좀 더 보완한다면 흰 지팡이의 대체품으로 사용이 가능할 것이다. 검출 범위는 사용자가 착용 시 3m내에서 사람이나 사물인식 실험 결과 약 88%이상의 인식률을 나타내었다.
