At the same time the processed
images were of lower resolution, which also degrades results in
terms of point density. Results on the comparison table 1 verify
that proposed method is more accurate than the traditional
process or the hybrid process. The small difference between the
photogrammetric and hybrid method may be attributed on the
fact that the hybrid method uses a full 3D model instead of a
2.5D for rectification, hence minimizing errors on complex
geometrical forms, such as vertical walls.
