초록
사회가 발전하면서 자동차의 수요도 세계적으로 급증하고 있다. 교통제어나 차량에 연관된 범죄 등을 해결하는데 자동차의 인식 기술이 중요하기 때문에 이에 관련된 번호판 인식이나 교통량 측정에 관한 연구는 오래 전부터 수행되어왔다. 본 논문에서는 주행차량의 제조회사와 차량 모델을 인식하는 방법을 제시하였다. 차종의 인식은 차량 전면부 영역의 질감을 이용하여 인식하였다. 번호판 상단의 라디에이터 영역에서 질감 특징자를 추출하여 신경망을 통한 차종별 학습을 시켜서 인식을 시도하였다. 제안 알고리즘에서 차종의 정인식은 93.7%, 이종차량의 감별은 99.7%로 양호하게 나타났다.
Abstract
The number of vehicles are rapidly increased as our society is developed. The vehicle recognition has been studied for a while because many people acknowledged it has critical functions to solve the problems of traffic control or vehicle-related crimes. In this paper a novel method is proposed to recognize vehicle models corresponding makers. Vehicles' models are recognized based on the texture parameters from segmented radiator region above a number plate. A three-layer neural network was built and trained with the texture features for recognition. The proposed method shows 93.7% of recognition rate and 99.7% of specificity for vehicles' model.
