Abstract

This study was carried out to effectively perform relative color correction for high-resolution aerial ortho image. For this study, relative geometrical error between adjacent images was analyzed. The block sum method is proposed to reduce the relative geometrical error. We used the regression coefficients determined based on the block sum size to perform the color correction. As a result, it was confirmed that the relative color correction was visually performed well. Quantitative analysis was performed through histogram similarity analysis. It is proved that block sum method is useful for relative color correction. Particularly, the block sum size was very important to correct color based on the amount of relative geometrical error.

본 연구는 동일 촬영시기 정사영상에 대한 색상보정을 효과적으로 수행하기 위하여 실시되었다. 이를 위하여, 인접 영상 간 상대적인 지상좌표 위치오차를 분석하였다. 위치오차를 저감시키기 위한 방법으로 block sum 방법을 제시하였다. 각각 block sum 크기에 따라 결정된 회귀계수를 이용하여 상대색상보정을 수행하였다. 그 결과 시각적으로 상대색상보정이 잘 수행되었음을 확인하였다. 정량적인 분석은 히스토그램 유사성 분석을 통해 수행되었다. 이로부터 block sum 방법이 상대색상보정에 유용함이 증명되었다. 특히 상대적인 지상좌표 위치오차의 양에 따라 block sum 크기의 선정이 매우 중요한 것으로 나타났다. 위치오차가 클수록 높은 크기에서의 block sum 적용이 유용한 것으로 확인되었다.
