Abstract

Robot-assisted illuminating equipment based on image-processing technology was developed and then its accuracy was measured. The current system was designed to detect facial appearance using a camera and to illuminate it using a robot-assisted system. It was composed of a motion control component, a light control component and an image-processing component. Images were captured with a camera and following their acquisition the images that showed motion change were extracted in accordance with the Adaboost algorithm. Following the detection experiment for the oral cavity of patients based on image-processing technology, a higher degree of the facial recognition was obtained from the frontal view and the light robot arm was stably controlled.

본 연구에서는 영상처리 기술을 활용한 치과용 로봇 조명장치를 개발하여 그 정확도를 측정하여 보고자 한다. 본 연구를 통해 개발된 치과용 로봇 조명장치는 환자의 얼굴을 카메라로 인식을 하여 구강의 위치를 찾아 로봇이 움직여 라이트를 비추게 하는 것으로서 모션 제어 부, 라이트 제어 부, 영상 처리부로 구성되어 있다. 카메라로 영상을 획득 후 동작변화 영상을 추출 한 다음 아다부스트 알고리즘(Adaboost algorithm)을 통해, 얼굴 검출에 필요한 특징을 추출하여 실시간으로 얼굴 영역을 검출하도록 하였다. 영상처리를 통한 환자 구강의 추출 실험 시 정면영상에서 높은 얼굴인식률을 나타냈고 얼굴영역이 인식이 되면, 안정적인 라이트 로봇 암(Light robot arm)의 제어가 가능했다.
