Abstract

In this paper, we address the problem of center lane detection algorithm for autonomous driving. Color information for center lane is gathered by analyzing a row line color distribution of road in front of a vehicle. The candidate pixels for center lane are extracted from the histogram of road colors. Morphological filtering and clustering process are applied to the candidate pixels to extract the exact center lane. We predict a expected area of center lane and search only the regions in subsequent frames, that reduces the time required for center lane detection.

본 논문에서는 지능형 운전 시스템을 위한 중앙 차선 검출 알고리즘을 제안 한다. 차량의 진행 방향에 있는 가로 한 줄의 색상 정보를 분석하여 중앙 차선에 대한 색상 정보를 얻는다. 이를 기반으로 차선 경계값을 설정하고 형태학적 연산처리와 클러스트링, 그리고 가상 직선화를 통해 중앙 차선을 검출한다. 또한 예상 차선 영역을 설정하여 다음 영상 프레임에서 전체 영상이 아니라 예상 영역에서 차선을 탐색하게 하여 차선 검출 속도를 높였다.
