The UltraMap/Essentials module is responsible for converting the raw images taken by the UltraCam into standard file formats that can be used by further processing steps in UltraMap and/or third party software systems. The UltraMap/Essentials module is divided into two processing steps:
The UltraMap/RawDataCenter step is responsible for processing the UltraCam imagery from level-0 to level-2. By exploiting the distributed UltraMap Framework, processing tasks can be handled in parallel.
UltraMap/Radiometry is the optimal solution to color balance level-2 input data and to generate level-3 imagery. The UltraMap radiometry adjustment is fully automated and at the same time provides a rich parameter set to adjust the color and visual appearance of a single image as well as of an entire image block. It is the single most-efficient software module to radiometrically align nadir and oblique imagery.
UltraMap/AT is used to accurately geo-position each UltraCam image. For the special case of the UltraCam Osprey, both, oblique and nadir imagery are adjusted in the aerial triangulation process to maximize geo-positioning accuracy. This is especially important for creating advanced down-stream products like textured 3D city models. The integrated Visual Analytics tools allow UltraMap users to intuitively understand the spatial layout of even the largest project and to quickly detect and correct any data issues.
The UltraMap/DenseMatcher module creates high-density point clouds, DSMs and DTMs from level-2 images by extrapolating precise exterior orientation data to generate per-pixel height values. The 3D point cloud and the DSM data can be exported in standard file formats for further 3rd party processing. The DSM Editor provides a sophisticated 3D interface for quick DSM inspection and modification.
UltraMap/OrthoPipeline module generates the final ortho mosaic from all
available inputs such as level-2 imagery, AT results, radiometric settings, and
the DSM/DTM. Two different ortho images can be generated: DSMOrthos and
