Digitization of Metric Camera and Large Format Camera space photographs
Abstract
Black and white images of the space shuttle experiments Metric Camera and Large Format Camera were digitized. Investigations show that it is possible to digitize space photographs at an accuracy which corresponds to the resolution of the film. It is demonstrated that the choice of a too small pixel size leads to a loss in the detectability of details within the images because of the apparent film grain. The reseau-scanner Rollei RS1 can cope with the high requirements in terms of geometric accuracy and resolution necessary for photogrammetric applications.
