There is concern when orienting push broom type data
using an iterative solution that correlations between the
unknowns may cause instability in the solution. Tests
were carried out to determine the effect of weighting on
the solution. Weighting the quality of the conjugate
points was thus tested with only a small improvement in
the final relative orientation.
It is expected that three-line stereo systems will
overcome most of the problems with convergence. A
larger number of equations per point identified in the
images will contribute toward a more stable solution.
In general, the polynomial model has more problems of
convergence with conjugate points than the physical
model.
