Photogrammetry knowledge
An overview of photogrammetry knowledge, its most important terms, and techniques.
- Automatic target detection - AutoGCP algorithm
- Camera distortion
- Coordinate reference systems and 2D projections
- Tie points in photogrammetry project (GCPs, CPs, MTPs, and ATPs)
- Ground sampling distance (GSD) in photogrammetry
- How are tie points errors defined - Mean, Sigma, RMS?
- How the onboard GPS affects the project accuracy?
- Is it possible to generate the orthomosaic of water surfaces?
- Number and distribution of ground control points (GCPs) in corridor mapping
- Orthometric vs ellipsoidal height
- Photo stitching vs orthomosaic generation
- Reprojection error
- Scientific papers about UAV and drone mapping
- TOOLS - GSD calculator
- TOOLS - Vertical pixel displacement calculator
- Vertical vs oblique imagery
- What is the relative and absolute accuracy of drone mapping
- What is... (a densified point cloud? an orthomosaic? etc.)
- Which factors affect the accuracy of the automatic aerial triangulation (AAT)?
- Yaw, Pitch, Roll and Omega, Phi, Kappa angles
