Vexcel Imaging announced the release of its UltraMap photogrammetric workflow software version 4.5.
With the introduction of oblique AT, a new camera modeling procedure and a custom-developed earth curvature correction, the UltraMap team realizes its vision of optimal aerial geometry.
The new enhancements are multiple. First, the new release includes substantially improved tie points for obliques and a full photogrammetric bundle adjustment for all viewing directions through targeted use of selected nadir and oblique images for AT.
This also allows for a more robust treatment of specific cases such as missing tie points in nadir.
Secondly, the newly introduced Accurate Camera Modeling (ACM), based upon the Temperature Dependent Modeling (TDM), further improves the geometry for all 3rd generation UltraCam systems.
The third step leading to optimal geometry is the implementation of a refined process for earth curvature corrections with a significantly positive effect on oblique image accuracy.
Finally, UltraMap 4.5 comes with a new option for tie point thinning allowing for the reduction of tie points.
“Vexcel is consistently working to improve our UltraMap software workflow to deliver more value to our customers,” said Alexander Wiechert, Vexcel Imaging CEO.” UltraMap users are sure to appreciate this new version for its improved overall georeferencing which augments the precision of building textures, the enhanced accuracy of 3D models, and the precise measurements in nadir and oblique imagery.”
