SUITABILITY OF THE SHARP JX-600 DESKTOP SCANNER FOR THE DIGITIZATION OF AERIAL COLOR PHOTOGRAPHS

摘要

Digitization of aerial photographs is one of the bottlenecks in the current transition phase in the introduction of fully digital photogrammetric systems. Owing to their low cost, desktop scanners offer an interesting alternative. This paper examines as a case study the suitability of the Sharp JX-600 desktop scanner for the digitization of aerial color photographs. The structure of the scanner is reviewed. A method for calibrating the scanner geometrically is given and the calibration results are presented. The image quality of the scanned images is analyzed. Finally, a method is introduced for calibrating the scanner individually for each scanned image.
