are critical components of transportation infrastructure, supporting heavy traffic loads and enduring long-term environmental exposure. Among various bridge structures, pile-column bridge piers with cap beams are widely used in highway bridges, overpas…

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 Establishing digital archives for historic buildings plays a crucial role in cultural heritage protection. High-precision 3D models generated through oblique photogrammetry provide reliable baseline data for conservation planning and stru…

UAV oblique photogrammetry solution supported large-scale rural cadastral surveying and 3D modeling in Salt Lake District, enabling accurate 1:500 mapping and property registration.

Project Overview Urban 3D reality modeling based on oblique photogrammetry is increasingly used in city construction, planning, and renovation. In this case, a detailed large-scale 3D model was created to support the urban renovation of an old residential a…
