Metric Calibration of the Aerial Photographic System by the Method of Mixed Ranges

Abstract

A new procedure for the calibration of the aerial photographic system is described and the results of a live data demonstration are reported. The procedure, termed the Method of Mixed Ranges (MMR), utilizes a three-dimensional targeted control range simultaneously with a conventional level range in an adjustment in which the elements of interior orientation are carried as common parameters for all exposures. The use of the three-dimensional range for suppressing high correlations between certain elements of interior and exterior orientation is though to be unique for the normal aerial case. The report describes the theory and results of the application of the MMR procedure to the Casa Grande and Mt. Graham ranges located in Arizona. Ten photographs were simultaneously adjusted. The rms error of photo coordinate-residuals after adjustment was 5.1 micrometers determined from 250 coordinate observations.
