Comparative Assessment of Surface Mapping Procedures Using Images Acquired by the Digital High-Resolution UltracamD Camera
Supplementary to spaceborne sensors, digital large format cameras
- like for instance the UltracamD camera – may be operated in airborne
campaigns in order to acquire image data with
extremely high resolution. Highly redundant image material may be
achieved due to a high overlap of sequentially acquired images. This
can be favourably utilized for surface reconstruction. In
this paper a comparative assessment of approaches for surface mapping
is presented, using data sets acquired by the UltracamD camera. Comparison
is made between the results achieved when using a single image pair
with some 60 percent overlap only versus the results which are achieved
when utilizing the multi-image coverage in a simultaneous manner.
The multi-image
based mapping procedures are presented, and their benefit is high-lighted
in a comparative assessment with respect to standard stereo mapping.
