Abstract
Aerotriangulation by independent model (AIM) was
performed on Wild A-7 Autograph using wide angle photographs
of average scale of 1,8000. In performing the
Aerotriangulation, the relative orientation was carried
out by numerical method and the model coordinates of
the perspective - centre; employed for the model
connections was measured.
The research seeks to establish the accuracy of
AIM by using different densities and distributions of
points for numerical relative orientation and twenty
perspective - center determinations.
Practical investigation reveals that cases of the
same density will produce similar results irrespective
of differences in distribution.
The accuracy of strip formation was found to be
dependent on the distribution and density of points
used for numerical relative orientation of the first
model. For instance case 1 with only six points has
accuracies of ± 0.1612 mm in planimetry and ± 0.163 mm
in height, case 25 with fifteen relative orientation
points has accuracies of ± 2.933 mm in planimetry and
± 0.505 mm in height.
