초록
최근에, 효율적인 상호작용을 지원하는 시스템 인 휴먼 머신 인터페이스(HMI)가 인기를 끌고있다. 본 논문에서는 차량 상호작용방법 중하나로 새로운 실시간 저비용 손동작 제어 시스템을 제안한다. 계산 시간을 줄이기 위해 RGB 카메라를 사용하여 손 영역을 감지할 때 많은계산이 필요하므로 TOF (Time-of-Flight) 카메라를 사용하여 깊이 정보를 취득한다. 또한, 푸리에 기술자를 사용하여 학습 모델을 줄였다. 푸리에 디스크립터는 전체 이미지에서 적은 수의 포인트만 사용하므로 학습 모델을 소형화 할 수 있다. 제안 된 기법의 성능을 평가하기 위해 데스크탑과 라즈베리 pi 2의 속도를 비교했다. 실험 결과에 따르면 소형 임베디드와 데스크탑의 성능 차이는 크지 않다. 제스처 인식 실험에서 95.16 %의 인식률이 확인되었다.
Abstract
Recently, a system that supports efficient interaction, a human machine interface (HMI), has become a hot topic. Inthis paper, we propose a new real time low-cost hand gesture control system as one of vehicle interaction methods. In order to reduce computation time, depth information was acquired using a time-of-flight (TOF) camera because itrequires a large amount of computation when detecting hand regions using an RGB camera. In addition, fourierdescriptor were used to reduce the learning model. Since the Fourier descriptor uses only a small number of points inthe whole image, it is possible to miniaturize the learning model. In order to evaluate the performance of the proposedtechnique, we compared the speeds of desktop and raspberry pi2. Experimental results show that performancedifference between small embedded and desktop is not significant. In the gesture recognition experiment, therecognition rate of 95.16% is confirmed.
