Vadstena 3D Reality‑capture System

Melown Technologies designs, develops and operates a proprietary, fully automatic 3D natural and urban landscape reconstruction software system, codenamed Vadstena. From a single set of aerial images, Vadstena produces a geometric 3D model, orthoimagery, DEM and land cover in a single unified, automatic process.

Vadstena is based on extensive in-house R&D in the fields of structure from motion, image processing, pattern recognition, computational geometry, and convolutional neural networks.

Designed from the start for clustered, multi-node operation, Vadstena achieves near-linear scalability and is applicable to very large projects, spanning entire cities or countries. Within Melown Technologies, it is operated on an off-the-shelf server farm comprising six computational nodes, 28 CPU cores and 19 GPUs.

Vadstena can handle diverse types of input data, including UAV-based close-range imagery, datasets from oblique camera systems, and low-overlap nadir imagery. Vadstena native output formats are open and documented. By adherence to the ESRI I3S specification, the output is readily usable in the geospatial industry.

Vadstena is currently not available for commercial licensing, but is accessible through ​Melown Photogrammetry.
