3. The influence of errors in the inner orientation
is found as the sum of a) the influence of the pseudo-values which
are introduced on the elements of outer orientation and b) the
direct influence of errors in the inner orientation.
The y-parallax in the six orientation points is derived from
(1) and (5):
pi Se (dey — der) + (di —d'n)1; i=1,.. 6 (Ba)
where
0: 2-19
B == 1]; 2-34 (8b)
„Al 150
Introducing (8) into (4), the expressions of the pseudo-values
are derived. The influence of the pseudo-values on the model
coordinates is obtained by introducing these expressions into (7).
The direct influence of errors in the inner orientation is found
by introducing (1) into (6). The total effect is:
