초록

안전하고 쾌적한 도시 환경을 조성하기 위해 폐기물 매립 시설은 필요하며 폐기물 부피 관리의 신뢰성 및 용량 정보의 정확성을 파악하는 것이 필요하다. 이 논문에서는 쓰레기 매립의 표준화를 위한 일환으로 쓰레기 체적을 주기적으로 계산하는 알고리즘을 제시하였다. 스테레오 카메라 캘리브레이션 이후에 대상체의 표면에 대한 포인트 클라우드(point cloud)를 얻을 수 있었으며 이것을 물체의 체적 계산 알고리즘의 입력으로 선택하였다, 비균일 삼각 격자 기반 메싱(non-uniform triangular meshing) 방법에 기초한 두 개의 체적 계산 알고리즘을 제안하였으며 알고리즘의 타당성을 시뮬레이션과 실제 실험을 통해 입증하였다. 제시된 알고리즘은 쓰레기 매립의 체적 계산 뿐 만이 아니라 삼차원 객체의 일반적인 체적 계산을 위한 알고리즘으로도 사용될 수 있다.

For the construction of safe and clear urban environment, it is necessary that we identify the rubbish waste volume and we know the accuracy volume. In this paper, we proposed the algorithm computes the waste volume periodically for the way of waste repository standard. After stereo camera calibration, we obtained the point cloud on the surface of the object and took this as the input of the calculation algorithm of the object volume. We proposed the volume calculation algorithms based on the non-uniform triangular meshing methods and verified the validity of the algorithm through simulation and real experiments. The proposed algorithm can be used not only as the volume calculation of the waste repository but also as the general volume calculation of a three dimensional object.
