This paper analyzes the effect of exterior orientation elements on vertical parallax, especially using the orientation
parameters of aerial images obtained by a POS (Positioning and Orientation System) after calibration. Firstly, based on
the theory of analytical relative orientation of consecutive photo connection, the exterior orientation elements can be
easily translated to relative orientation elements. Then, the formula of vertical parallax can be deduced. The results of
vertical parallax in left image space coordinate system are compared with the results calculated in the image coordinate
system which are parallel to those of the object coordinate system. The validity and feasibility of the mathematical model
are tested using two sets of actual data at different images scales. Finally, the differences between the effects of exterior
orientation parameters on vertical parallax are compared using exterior orientation parameters obtained by traditional
bundle block adjustment and by a POS after calibrated. And how the single element of exterior orientation effected on
vertical parallax and how they worked together are analyzed. The empirical results indicate that the effects of different
elements of exterior orientation on vertical parallax are different, all exterior orientation parameters can be affected by
each other, so the overall effect of vertical parallax accuracy can be restricted by all exterior orientation parameters.
