A new computation procedure for calculation od both the interior and exterior orientation elements from a single non-metric photograph based on the collinearity equation and ''an algorithm for a least-squares estimation of nonlinear parameters'' (Marquardt, 1963) has been investigated in detail. In this procedure, the traditional intermediate step of transforming image coordinates from a comparator system to a photo-coordinate system is by-passed. An experimental verification of the proposed technique has been carried out. The experimental results support the conclusion that the developed calculation procedure offers a theoretical and practical alternative to the existing models for the on-the-job calibration of non-metric cameras.
