Abstract
A study of the Image Quality Effects on Image Measurement in an aerial mapping camera (Zeiss RMK reseau) is reported. A laboratory experiment was designed and conducted to investigate the effects of of resolution, contrast transfer and edge sharpness (acutance) on image measurement in various locations of the photographic format. Glass plate targets containing multiple contrast three bar patterns and a standard resolution target were photographed through a light source collimator-camera system. A microanalyzer (microdensitometer combined with a precise comparator integrated with analog and digital recording capabilities) was used for the studies. Over two thousand edge measurements were made. The results indicate that, among other things, certain image quality parameters may be the controlling ones over image measurement capabilities in a given area of the photographic format.
