Castle Ruin Donaustauf
The 3d reconstruction of this castle ruin was a very challenging task:
- Located on a steep hill, direct access is limited (i.e. for employing large lifting platforms)
- The topology has huge height deviations which prohibits the efficient use of 3d laser scanners
- We therefore used a combination of aerial (octocopter), high-mast and ground images for the 3d reconstruction
Church Tower Landshut
This is the highest church brick-tower in the world (130m).
We documented the entire tower with 2.200 images using UAVs in order to pin-point building damages.
The deliverables were 8 high-res (27.000px height / 0.5cm resolution) geo-referenced orthoimages together with an online image database (with all source images meta-tagged for efficient classification).
Detailed photogrammetric 3d-reconstructions based on dense stereo-matching / structure from motion, i.e. for renderings and Virtual / Augmented Reality.
