Abstract:
| 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. |
