Paper Abstract

The effects of the graininess of the photographic emulsion on the radiometric noise of the digital data are investigated, particu- larly the degradation of the precision of point matching in stereo pairs. For small pixel sizes, e.g. 7.5 pm in the new Zeiss digiti- zer, the radiometric noise due to graininess can amount to more than 20 per cent of signal. In contrast to that the radiometric noise of a directly rasterizing CCD-camera usually is only a few thousands of the signal.
