A COMPARATIVE ANALYSIS OF PHOTO COORDINATES MEASURED STEREOSCOPICALLY AND MONOCULARLY
Abstract
A comparison is made between the accuracies of photo coordinates measured on a monocular comparator and stereocomparator. Methods are derived based on the reseau type photograph and the method of least squares to transform from comparator coordinates to photo coordinates correcting for rotation, transverse and longitudinal film shrinkage and lens distortion. An analysis of the data based on approximately 70 independent adjustments indicates that the monocular comparator will yield adjusted coordinate accuracies slightly superior to those of the stereocomparator when working with reseau type photography. The consistently smaller standard errors of x coordinates as compared to the y coordinates leads to the recommendation for weighting of the measurements for either of the two comparators used during the investigation.
