The Impact of Processing Parameters on High-Accuracy Measurements in UAV Photogrammetry
Paweł Ćwiąkała, Edyta Puniach, Elżbieta Pastucha & 1 other
What they foundProcessing settings alone moved drone survey accuracy from 16 mm to 303 mm RMSE; the number of ground control points mattered most.
Why it mattersHow you process the photos matters as much as how you fly.
What they studied
768 processing variants on ten drone datasets over a 220-hectare site.

Uncertainty Quantification Framework for Aerial and UAV Photogrammetry through Error Propagation
Debao Huang & Rongjun Qin
What they foundA framework gives per-point accuracy estimates for photogrammetry point clouds, including the hard multi-view stereo step.
Why it mattersSurveyors need to know how accurate each point is, not just the average.
What they studied
Error-propagation methods for aerial and drone photogrammetry.

A volumetric change detection framework using UAV oblique photogrammetry - A case study of ultra-high-resolution monitoring of progressive building collapse
Ningli Xu, Debao Huang, Shuang Song & 5 others
What they foundDrone images tracked a building's collapse during demolition, with point clouds within 12–16 cm of LiDAR.
Why it mattersIt shows drones can monitor 3D change without ground control points.
What they studied
A case study with multi-temporal oblique drone photogrammetry.

Integrating BIM and UAV-based photogrammetry for Automated 3D Structure Model Segmentation
Siqi Chen & Shanyue Guan
What they foundMachine learning trained on drone scans plus BIM data automatically picks out rails and crossties in 3D models.
Why it mattersIt cuts the manual labelling that slows infrastructure inspection.
What they studied
Validation on a railroad track dataset.
