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