Abstract

The accuracy of OTF and MTF measurements of aerial cameras and photographs is discussed. Modulations for positions at 40° off axis have to be determined for the wide angle cameras commonly used in photogrammetry. Instead of sinusoidal test patterns, natural edges on the ground can be utilized in practical aerial photography. The particular problems concerning measurements of emulsions are dealt with. The possibility of utilizing photo interpretation results or photogrammetric measurements of ground details as an aid for establishment of a quality criterion for aerial photographs is discussed.
