Abstract

This paper aims to detect Speed Bump by using Omni-directional Camera and to suggest Real-time update scheme of Speed Bump through Vision Based Approach. In order to detect Speed Bump from sequence of camera images, noise should be removed as well as spot estimated as shape and pattern for speed bump should be detected first. Now that speed bump has a regular form of white and yellow area, we extracted speed bump on the road by applying erosion and dilation morphological operations and by using the HSV color model. By collecting huge panoramic images from the camera, we are able to detect the target object and to calculate the distance through GPS log data. Last but not least, we evaluated accuracy of obtained result and detection algorithm by implementing SLAMS (Simultaneous Localization and Mapping system).

본 연구에서는 전방위 카메라(Omni-directional Camera)를 이용하여 과속방지턱(Speed Bump)을 탐지하고 Vision Based Approach 통한 실시간 과속 방지턱 데이터의 갱신 방안을 제시하는 것을 목적으로 한다. 카메라 영상정보에서 과속 방지턱을 검출하기 위해 잡음을 제거하고 이를 구성하는 형상과 패턴으로 여겨지는 점들을 우선적으로 탐지하여야 한다. 과속방지턱은 일정한 폭과 규칙적인 형태를 유지하며 흰색과 노란색의 영역을 가지고 있음에 착안하여 침식과 팽창을 이용한 형태학적 연산과 HSV칼라 모델을 적용하여 도로상의 과속방지턱을 추출하였다. 카메라에서 거대한 이미지 데이터를 수집하여 대상 객체를 검출하고 GPS 위치 정보를 이용하였다. 마지막으로 동시적 위치추정 및 지도작성 (SLAMs :Simultaneous Localization And Mapping) 시스템을 구현하여 탐지알고리즘과 취득결과의 정확성을 평가하였다.
