Abstract

This paper proposes a real-time processing method to simplify the image input procedure while extracting and tracing a specified object among multiple ones. In order to extract an object in a specified area among multiple objects of indoor environment and tracing the extracted object continuously, it is verified through experiments that the information interchanged between cameras upwards and in front of it have effect on tracing a specified object continuously. The camera located upward transfers its x-axis data of the input image to the front camera so that the front camera can catch the area of object soon without computing the information of x-axis. The front camera can't resolve the problem of objects overlapping till they share information with the upward camera. The result of the experiment shows that the computation for tracing an object is simplified and the accuracy for extracting and tracing is upgraded.

본 논문에서는 다중객체 환경에서 특정한 객체를 추출과 추적을 하기 위하여 입력되는 영상의 처리과정을 간소화하여 실시간으로 수행할 수 있는 방법을 제시하였다. 실내환경의 많은 객체들 중 특정영역에 입력되는 객체를 추출하고 추출된 객체를 지속적으로 추적하기 위하여 상단의 카메라와 전면의 카메라의 상호정보교환을 통하여 특정 객체를 지속적으로 추적할 수 있음을 실험을 통하여 검증하였다. 상단의 카메라에서 입력받은 영상에서 x 축의 정보를 전면의 카메라에 전송하여 전면의 카메라는 객체의 x축 정보를 계산하지 않고 빠르게 객체영역을 획득할 수 있으며, 전면카메라에서는 객체들 간의 겹침현상을 해결할 수 없지만 상단의 카메라와 정보를 공유하므로 객체들 간의 겹침현상을 해결할 수 있었다. 실험결과 기존의 객체추적 시스템보다 객체를 추적하기위한 연산량이 줄어들었으며, 객체추출 및 추적의 정확성이 향상되었다.
