Abstract

This Paper is for A study of sensor fusion using Radar sensor and Vision sensor in moving object detection. Radar sensor has some problems to detect object. When the sensor moves by wind or that kind of thing, it can happen to detect wrong object like building or tress. And vision sensor is very useful for all area. And it is also used so much. but there are some weakness that is influenced easily by the light of the area, shaking of the sensor device, and weather and so on. So in this paper I want to suggest to fuse these sensor to detect object. Each sensor can fill the other's weakness, so this kind of sensor fusion makes object detection much powerful.

본 논문은 레이더 센서, 비전 센서를 활용한 다중 센서 융합 기반 움직임 검지에 관한 연구를 다룬다. 레이더 센서는 다량의 물체를 검지함에 있어 센서 자체의 움직임이 발생할 경우 주변건물이나 주변 가로수와 같은 사물 혹은 물체를 차량으로 오인하는 경우가 생긴다. 비전 센서의 경우 저렴하고 가장 많이 쓰는 형태이지만 빛, 흔들림, 날씨, 조도 등 외부환경에 취약하다는 문제점이 있다. 각 센서 간의 문제점을 보완하고자 센서 융합을 통한 움직임 검지를 제안하게 되었고 실험환경 내에서 매우 우수한 검지율을 보이게 되었다 센서 간 융합에서 좌표 통일문제와 실시간 전송문제 등을 해결하였으며, 각 센서 간 필터링을 통한 비가공데이터(raw data)의 신뢰성을 높였다. 특히 영상에서는 가우시안 혼합모델(GMM, Gaussian Mixture Model)을 사용하여 레이더 센서의 단점을 극복하고자 했다.
