Abstract

In this paper, we propose a stereo image recognition-based method for measuring the volume of the rectangular parallelepiped. The method measures the volume from two images captured with two CCD (charge coupled device) cameras by sequential processes such as ROI (region of interest) extraction, feature extraction, and stereo matching-based vortex recognition. The proposed method makes it possible to measure the volume of the 3D object at high speed because only a few features are used in the process of stereo matching. From experimental results, it is demonstrated that this method is very effective for measuring the volume of the rectangular parallelepiped at high speed.

본 논문에서는 스테레오 영상 인식에 기반한 직육면체형 물체의 부피를 계측하는 한 방법이 제안된다. 제안된 방범은 두 대의 CCD(charge coupled device)카메라로부터 획득된 영상에 대하여 관심영역추출, 특징 추출, 그리고 스테레오 정합에 기반한 꼭지점 인식의 과정을 통하여 3D 물체의 부피를 계측한다. 제안된 방법은 3D 물체의 특징을 나타내는 꼭지점 후보들을 영상처리과정을 통해 추출한 후, 이들 꼭지점들에 대해서만 스테레오 정합을 수행함으로써 고속의 부피 계측이 가능한 이점이 있다. 실험을 통하여, 본 논문에서 제안한 방법이 직육면체형 물체의 고속 부피계측에 효과적으로 사용될 수 있음이 보여진다.
