Precise Measurement of Photographic Coordinates Utilizing Edge Information.
Abstract
Information from the fields of metrology, optics, photogrammetry, psychology, opthalmology, and physiology was used to determine the significance of the quality, quantity and distribution of edge information and the precision of coordinate measurement. The basis for examining the precision of coordinate measurement is the negative-reticle concept where the objective is to provide a reticle which is as close to the negative of the target as possible. During the investigation the following factors were analyzed to determine their effect on measurement precision using the above concept: observer, target contrast, x and y coordinates, reticle density, target shape, and target size.
