CCD Camera Scanner의 스캐닝 왜곡 보정기법 연구
Correction for Scanning Errors of a CCD Camera Scanner
초록
촬영된 사진이나 음화 또는 양화필름을 스캐닝할 때에는 스캐닝에 따르는 기하왜곡이 발생하게 된다. 스캐닝 기하왜곡을 보정하기 위하여는 스캐닝 대상물상에 평면위치를 정확하게(수
One can see more and more photograrmmetric applications dealing with the extraction of information from images obtained with CCD (Charge Coupled Device) camera scanners. In order for this information to be useful, the scanning errors of scanners must be known through a calibration. Investigation of this study is given to the detailed procedure of the correction for scanning errors created during the scanning of photographs with CCD camera scanner using the three kinds of high resolution reseal plates prepared. The geometric corrected digital images for scanning errors were generated and the accuracy of the resulting new images for each types of plates were checked comparing its image coordinates with there corresponding ground coordinates for the check points.
