What It Solves
Reconstruct 3D structure and camera poses from 2D drone imagery where no prior metrics are available, enabling photogrammetry and radiance-field initialization.
Primary use cases
- Structure-from-motion from overlapping drone images
- Multi-view stereo dense reconstruction
- Initialization of photogrammetry and radiance-field workflows
Secondary use cases
- Creation of sparse/dense point clouds for inspection
- Camera calibration and pose estimation
When to Use
Consider when
- You have overlapping UAV imagery and need metric 3D models
- Pre-processing step before radiance-field training
