daily operations, Riebo’s technical team frequently receives customer inquiries about speckle artifacts appearing in 3D photogrammetry models. The issue has become so common that it is even included as an internal technical assessment question: under what c…

drone-based oblique photogrammetry and 3D reality modeling, vegetation—especially trees—has long been considered one of the most difficult elements to reconstruct accurately. Unlike buildings and infrastructure with clear geometric structures, trees present…

oblique photogrammetry projects, holes appearing in water surfaces, walls, or other structures are very common. This issue is often considered a persistent challenge in aerial mapping data processing. This article explains the five common types of model hol…

Project Background In highway planning and design, acquiring high-precision topographic data and realistic 3D models is essential for route selection, engineering analysis, and construction planning. Traditional surveying methods often struggle in mountaino…

Project Background Creating digital archives for historic buildings plays a crucial role in cultural heritage preservation. High-precision 3D models generated through oblique photogrammetry provide reliable baseline data for future conservation work while e…
