Fit Evaluation of the Image Segmentation Modelling for DEM Generation of Satellite Image
위성영상의 DEM 생성을 위한 영상분할 모델링 방법의 적합도 평가
Abstract
In this study, for efficient replacemen of sensor modelling of high-resolution satellite imagery, image segmentation method is applied to the test area of the SPOT-3 satellite imagery. After that, a third-order polynomial model in the sectioned area is compared with the RFM which is to the entire in the test area. As results, plane error of the third-order polynomial model is lower(approximately 0.8m) than that of RFM. On the other hand, height error of RFM is lower(approximately 1.0m).
