railway engineering, survey and design represent a critical early stage that directly impacts construction quality, safety, and cost control. With the rise of 3D visualization technologies, oblique photogrammetry has emerged as a breakthrough tool, transfor…

“Smart 3D China” driving the market, user demand for oblique photogrammetry models has shifted from pure accuracy toward a more critical need—realistic visual representation. As a manufacturer that has always prioritized modeling quality in R&D, Riebo…

today’s rapid development of oblique photogrammetry technology, the optical performance of lenses often draws the most attention. However, the true core that supports precise modeling—synchronization control technology—often exists as a “hidden parameter.” …

oblique aerial photogrammetry, surveyors employ various measures to improve model accuracy. Among these, the layout of ground control points (GCPs) is one of the most fundamental methods. The selection of GCP locations and the accuracy of their coordinates …

underground pipelines are often referred to as the “lifelines of a city.” Their efficient management is critical to ensuring smooth urban operations and improving living environments. In the eastern part of Jinan’s main urban area, a 3D underground pipel…
