RTK-Ob Oblique Photogrammetry UAV

Oblique 5-Camera Realistic 3D Modeling with RTK

The RTK-Ob Oblique Photogrammetry UAV delivers realistic, true-to-life 3D city and site models by capturing five viewing angles in a single pass. An oblique camera rig with a combined high-resolution sensor set records front, back, left, right and nadir views simultaneously, giving 3D modelling software everything it needs to reconstruct buildings, bridges and terrain with photorealistic texture. Centimetre-level RTK positioning georeferences every image, and PPK support adds accuracy where RTK coverage is weak. Automated block planning and control-point integration streamline the workflow from capture to model. Applications range from smart-city digital twins and heritage documentation to construction progress and real-estate visualisation.
