the combined bundle block adjustment is highest when the
two periods of imageries are at the same scale. Comparing
table 3 with table 2, we can learn that the exterior
orientation elements of new imageries obtained in this
paper are close to the ones calculated by the conventional
bundle block adjustment with GCPs. And the accuracy of
3D coordinates of all photogrammcetric points is identical
between the two methods.
accuracy will decrease apparently when small-scale fixed
imageries are used to calculate the exterior orientation
elements of large-scale imageries in the same area. The
planimetric accuracy of densification points doesn't
change much, but the height accuracy decreases terribly.
In spite of the fact that the adjusted results still meet the
specification for 1:1,000 topographic mapping in
mountainous area. The coordinate residuals of check
points are less than 5.0m in planimetry and 3.0m in height
