Photogrammetry DRONE-LIFT-OFF

3D scanning with drones / camera multirotor

The principle of 3D model creation

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

  • Resolution of the model

    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.

    Water tower 3D scan with drone

    [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.

    Drone chapel

    [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.

    House roof 3D scan with drone

    [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.
