Photogrammetry – 3D models
Photogrammetry is a cocktail of photographical skills, use of the appropriate soft- and hardware and patience.
Drones are used to capture the needed images.
1. Photo capturing,
2. Point cloud production, Aero triangulation, 3D models,
3. Measurement of distance, surface and volumes,
4. Integration in google earth, CAD software for construction projects.
GPS accuracy is in worst cases 7 meters, so the integration of the pictures on a map may be not perfect. However, if the pictures have embedded GPS date of the same day, accuracy is high. We manage to give up to 1 cm accuracy!
The ultimate synergy between photography, drone-operations and engineering.
