초록
최근 물체를 인식하기 위해 많은 데이터를 기반으로 학습하여 인식하는 연구가 활성화 되고 있다. 본 논문에서는 도로주행 영상에서 장애물이라고 생각되는 객체를 추출하여 자동차, 사람, 오토바이로 구분하여 인식하는 시스템을 제안한다. 이동한 방향과 크기를 고려한 상태에서 광류 추정 알고리즘을 이용하여 객체를 추출하였으며, 추출한객체를 CNN(Convolutional Neural Network) 인식 모델 중 하나인 AlexNet을 이용하여 인식하였다. 실험을 위해도로 위의 다양한 영상을 블랙박스로 수집하여 실험하였고, 실험 결과 객체 추출 정확도는 92%, 객체 인식 정확도는96%의 결과를 보였다.
Abstract
In recent years, research has been actively carried out to recognize and recognize objects based on a large amount of data. In this paper, we propose a system that extracts objects that are thought to be obstacles in road driving images and recognizes them by car, man, and motorcycle. The objects were extracted using Optical Flow in consideration of the direction and size of the moving objects. The extracted objects were recognized using Alexnet, one of CNN (Convolutional Neural Network) recognition models. For the experiment, various images on the road were collected and experimented with black box. The result of the experiment showed that the object extraction accuracy was 92% and the object recognition accuracy was 96%.
