Objects can be digitalized in 3 dimensions by photographing them from different camera angles (3D polygonal models).
Applications
- Object documentation in museums and archaeology
- 3D scans and views
- Documentation of constructions and renovations
- Damage assessment
- Advertisement medium in the web advertising industry
- Archives
- Illustrations in museums
- Historical documentations
Depending on the resolution of the camera and the distance of the multicopter to the scanned object, specific levels of detail can be obtained in the images.
[A] Medium to coarse resolution - flight distance of 10-50m: this example shows some limitations of this method (see details like railings) - real image on the left, photogrammetric 3D scan on the right.
[B] Fine resolution - flight distance of 3-15m: good scanning capability because of few filigree elements - real image on the left, photogrammetric 3D scan on the right.
[C] Fine resolution - flight distance 0.5-2m: very good level of detail to detect cracks. Higher line accuracy can be achieved using advanced software settings but only with enormous computer performances - real image on the left, photogrammetric 3D scan on the right.
