초록
This study introduces an automatic image matching algorithm that can be applied for the scale different imagepairs consisting of the satellite pushbroom images and the aerial frame images. The proposed method is basedon several image processing techniques such as pre-processing, filtering, edge thinning, interest point extraction,and key-descriptor matching, in order to enhance the matching accuracy and the processing speed. The proposedmethod utilizes various characteristics, such as the different geometry of image acquisition and the differentradiometric characteristics, of the multi-sensor images. In addition, the suggested method uses the sensor modelto minimize search area and eliminate false-matching points automatically.
