Abstract

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 developed the algorithm which computes the waste volume using the stereo camera for enhancing the environment of waste repository. Using the stereo vision camera, we first computed the distortion parameters of stereo camera and then we obtained the points cloud of the object surface by measuring the target object. Regarding the points cloud as the input of the volume calculation algorithm, we obtained the waste volume of the target object. For this purpose, we suggested two volume calculation algorithm based on the uniform meshing method. The difference between the measured volume such as today's one and yesterday's one gives the reposit of waste volume. Using this approach, we can get the change of the waste volume repository by reading the volume reports weekly, monthly and yearly, so we can get quantitative statistics report of waste volume.

안전하고 쾌적한 도시 환경을 조성하기 위해 폐기물 매립 시설은 필요하며 폐기물 부피 관리의 신뢰성 및 용량 정보의 정확성을 파악하는 것이 필요하다. 본 연구에서는 쓰레기 매립장 환경 개선을 위해 매립된 쓰레기의 체적을 스테레오 비전 카메라를 이용하여 계산하고 매립량을 계산하기 위한 알고리즘을 개발 하였다. 스테레오(stereo)) 카메라를 이용하여 왜곡 파라메타 교정을 한 후에 쓰레기 매립지의 대상 표면 점들의 클라우드를 얻게 되며 이를 체적 알고리즘의 입력으로 하여 제시된 두 가지 방법의 체적계산 알고리즘을 통해 대상체의 체적을 계산하게 된다. 그리고 이 부피 값과 비교하고자 하는 지난 시간의 체적 값을 감산하여 매립된 체적을 계산한다. 이를 통해 주간 매립 체적, 월간 매립 체적 및 년간 매립 체적을 계산하여 쓰레기 매립 제어를 위한 정량적인 통계값을 얻을 수 있게 된다.
