굴뚝연기의 혼탁도 측정하는 DOM(: Digital Optical Method)은 쉽게 구할 수 있는 저렴한 비용의 디지털 카메라를 이용해 측정하고자하는 구역과 그 대조 구역을 설정하여 혼탁도를 계산하는 방법이다. 그러나 흐린 하늘에서는 구름과 백색 굴뚝연기가 구분되지 않아 측정이 어려운 문제점 있다. 본 논문에서는 이러한 문제를 해결하기 위하여 배경하늘을 주기적으로 디지털 카메라로 촬영하고 유형을 분류하여 대표할 수 있는 배경하늘 유형 모델을 개발한다. 또한 개발된 배경하늘 유형 모델을 기반으로 백연 이미지 보정을 최적화하기 위한 필터를 개발하고 실험을 통하여 우수성을 입증한다.

The DOM (: Digital Optical Method), which measures the turbidity of chimney smoke, is a method of calculating the turbidity by setting the area to be measured and the contrast area using a low-cost digital camera that can be easily obtained. However, it is difficult to measure clouds and white smoke in a cloudy sky. In this paper, we develop a background sky type model that can represent the background sky and classify the type by periodically photographing it with a digital camera to solve this problem. In addition, based on the model, we develop a filter to optimize white smoke image and prove its excellence through experiments.
